104-662: In the  Falkland Islands  (red & white) West Falkland ( Spanish : Isla Gran Malvina ) is the second largest of the Falkland Islands in the South Atlantic. It is a hilly island, separated from East Falkland by the Falkland Sound . Its area is 4,532 square kilometres (1,750 square miles), 37% of the total area of the islands. Its coastline is 1,258.7 kilometres (782.1 miles) long. The island has fewer than 200 people, scattered around

208-560: A British overseas territory , the Falklands have internal self-governance , but the United Kingdom takes responsibility for their defence and foreign affairs. The capital and largest settlement is Stanley on East Falkland. The islands are believed to have been uninhabited prior to European discovery in the 17th century . Controversy exists over the Falklands' discovery and subsequent colonisation by Europeans. At various times,

312-496: A schistose character. The andalusite may be pink and is then often pleochroic in thin sections, or it may be white with the cross-shaped dark enclosures of the matrix that are characteristic of chiastolite . Sillimanite usually forms exceedingly minute needles embedded in quartz. In the rocks of this group cordierite also occurs, not rarely, and may have the outlines of imperfect hexagonal prisms that are divided up into six sectors when seen in polarized light. In biotite hornfels,

416-448: A self-governing British Overseas Territory . Under the 2009 Constitution , the islands have full internal self-government; the UK is responsible for foreign affairs, retaining the power "to protect UK interests and to ensure the overall good governance of the territory". The Monarch of the United Kingdom is the head of state, and executive authority is exercised on the monarch's behalf by

520-655: A UK expeditionary force retook the territories in June. After the war the UK expanded its military presence, building RAF Mount Pleasant and increasing the size of its garrison. The war also left some 117 minefields containing nearly 20,000 mines of various types, including anti-vehicle and anti-personnel mines. Due to the large number of deminer casualties, initial attempts to clear the mines ceased in 1983. Demining operations recommenced in 2009 and were completed in October 2020. Based on Lord Shackleton 's recommendations,

624-422: A UK overseas territory. The territory's sovereignty status is part of an ongoing dispute between Argentina and the UK . The population (3,662 inhabitants in 2021) is primarily native-born Falkland Islanders , the majority of British descent. Other ethnicities include French, Gibraltarians , and Scandinavians. Immigration from the United Kingdom, the South Atlantic island of Saint Helena , and Chile has reversed

728-807: A dispute related to fishing and hunting rights led to a raid by the American warship USS Lexington in 1831, when United States Navy commander Silas Duncan declared the dissolution of the island's government. Buenos Aires attempted to gain influence over the settlement by installing a garrison in October 1832, which mutinied within a month and was followed the next year by the arrival of British forces, who reasserted Britain's rule . The Argentine Confederation (headed by Buenos Aires Governor Juan Manuel de Rosas ) protested against Britain's actions, and Argentine governments have continued since then to register official protests against Britain. The British troops departed after completing their mission, leaving

832-501: A faint striping may indicate the original bedding of the unaltered rock and corresponds to small changes in the nature of the sediment deposited. More commonly there is a distinct spotting, visible on the surfaces of the hand specimens. The spots are round or elliptical, and may be paler or darker than the rest of the rock. In some cases they are rich in graphite or carbonaceous matter; in others they are full of brown mica; some spots consist of rather coarser grains of quartz than occur in

936-412: A few localities, it seems conspicuously absent from others. Most authorities at the present time regard the changes as being purely of a physical and not of a chemical nature. [REDACTED] The hornfels facies occupies the portion of the metamorphic pressure-temperature space of lowest pressure and low to high temperature. It is subdivided into a low-temperature regime of albite - epidote hornfels,

1040-416: A leased floating production, storage and offloading unit". A final investment decision had been targeted for early 2024, though it was somewhat delayed. A public consultation on the project took place in the summer of 2024 and was reported to have garnered widespread support from Falkland Islanders. Since Britain's newly elected Labour Government banned similar oil projects in the United Kingdom, this created

1144-535: A low population density . According to the 2012 census, the average daily population of the Falklands was 2,932, excluding military personnel serving in the archipelago and their dependents. A 2012 report counted 1,300 uniformed personnel and 50 British Ministry of Defence civil servants present in the Falklands. Stanley (with 2,121 residents) is the most-populous location on the archipelago, followed by Mount Pleasant (369 residents, primarily air-base contractors) and Camp (351 residents). The islands' age distribution

In the Second World War , following the December 1939 Battle of the River Plate , the battle-damaged HMS Exeter steamed to the Falklands for repairs. In 1942, a battalion en route to India was redeployed to

1456-423: A negative reputation due to cargo-shipping losses; only in emergencies would ships rounding Cape Horn stop at the port. Nevertheless, the Falklands' geographic location proved ideal for ship repairs and the "Wrecking Trade", the business of selling and buying shipwrecks and their cargoes. Aside from this trade, commercial interest in the archipelago was minimal due to the low-value hides of the feral cattle roaming

1560-494: A population decline. The predominant (and official) language is English. Under the British Nationality (Falkland Islands) Act 1983 , Falkland Islanders are British citizens . The islands lie at the boundary of the subantarctic oceanic and tundra climate zones, and both major islands have mountain ranges reaching 2,300 ft (700 m). They are home to large bird populations, although many no longer breed on

1768-480: A suite of new minerals, which may resemble those of the calcium-silicate hornfelses above described. The original porphyritic , fluidal, vesicular or fragmental structures of the igneous rock are clearly visible in the less advanced stages of hornfelsing, but become less evident as the alteration progresses. In some districts hornfelsed rocks occur that have acquired a schistose structure through shearing, and these form transitions to schists and gneisses that contain

1872-477: A third type of hornfels is produced. They consist essentially of feldspar with hornblende (generally of brown color) and pale pyroxene. Sphene, biotite and iron oxides are the other common constituents, but these rocks show much variety of composition and structure. Where the original mass was decomposed and contained calcite, zeolites , chlorite and other secondary minerals either in veins or in cavities, there are usually rounded areas or irregular streaks containing

1976-566: A very social place, and stopping for a chat is a way of life". The islands have one weekly newspaper, The Penguin News , and television and radio broadcasts generally feature programming from the United Kingdom. Wagstaff describes the local cuisine as "very British in character with much use made of the home-grown vegetables, local lamb, mutton, beef, and fish". Common between meals are "homemade cakes and biscuits with tea or coffee". Social activities are, according to Wagstaff, "typical of that of

2080-501: Is pegged to the British pound sterling . Economic development was advanced by ship resupplying and sheep farming for high-quality wool. The main sheep breeds in the Falkland Islands are Polwarth and Corriedale . During the 1980s, although ranch under-investment and the use of synthetic fibres damaged the sheep-farming sector, the government secured a major revenue stream by the establishment of an exclusive economic zone and

There is also quartz, and often a considerable amount of feldspar, while graphite, tourmaline and iron oxides frequently occur in lesser quantity. In these biotite hornfels the minerals, which consist of aluminium silicates, are commonly found; they are usually andalusite and sillimanite , but kyanite appears also in hornfels, especially in those that have

2392-511: Is debated by historians. In 1766, France surrendered its claim on the Falklands to Spain , which renamed the French colony Puerto Soledad the following year. Problems began when Spain detected and captured Port Egmont in 1770. War was narrowly avoided by its restitution to Britain in 1771. The British and Spanish settlements coexisted in the archipelago until 1774, when Britain's new economic and strategic considerations led it to withdraw

2496-455: Is latitude 51°40′  – 53°00′ S and longitude 57°40′  – 62°00′ W . The archipelago's two main islands are separated by the Falkland Sound , and its deep coastal indentations form natural harbours . East Falkland houses Stanley (the capital and largest settlement), the UK military base at RAF Mount Pleasant, and the archipelago's highest point: Mount Usborne , at 2,313 ft (705 m). Outside of these significant settlements

2600-482: Is outside Stanley or RAF Mount Pleasant on East Falkland it is considered part of the " camp ", a Falklander term for the area outside the main settlement. West Falkland is hillier on the side closest to East Falkland . The principal mountain range, the Hornby Hills , runs parallel with Falkland Sound . Mount Adam , the highest hill in the islands, is 700 metres (2,300 ft) above sea level. Formerly it

2704-660: Is skewed towards working age (20–60) . Males outnumber females (53 to 47 per cent), and this discrepancy is most prominent in the 20–60 age group. In the 2012 census, most islanders identified themselves as Christian (66 per cent), followed by those with no religious affiliation (32 per cent). The remaining 2 per cent identified as adherents of other religions, including the Baháʼí Faith , Buddhism , and Islam . The main Christian denominations are Anglicanism and other Protestantism , and Roman Catholicism . Education in

2808-1048: Is the area colloquially known as "Camp", which is derived from the Spanish term for countryside ( Campo ). The climate of the islands is cold, windy, and humid maritime . Variability of daily weather is typical throughout the archipelago. Rainfall is common over half of the year, averaging 610 mm (24 in) in Stanley, and sporadic light snowfall occurs nearly all year. The temperature has historically stayed between 21.1 and −11.1 °C (70.0 and 12.0 °F) in Stanley, with mean monthly temperatures varying from 9 °C (48 °F) in January and February (summer) to −1 °C (30 °F) in July (winter). Strong westerly winds and cloudy skies are common. Although numerous storms are recorded each month, conditions are normally calm. The Falkland Islands are biogeographically part of

The unemployment rate was 1% in 2016, and inflation was calculated at 1.4% in 2014. Based on 2010 data, the islands have a high Human Development Index of 0.874 and a moderate Gini coefficient for income inequality of 34.17. The local currency is the Falkland Islands pound , which

3640-562: The Anglo-Saxon term "folkland" (land held by folk-right ). The name "Falklands" was not applied to the islands until 1765, when British captain John Byron of the Royal Navy claimed them for King George III as "Falkland's Islands". The term "Falklands" is a standard abbreviation used to refer to the islands. The common Spanish name for the archipelago, Islas Malvinas , derives from the French Îles Malouines —the name given to

3744-594: The EEZ of Argentina. The UK and Argentina both assert sovereignty over the Falkland Islands. The UK bases its position on its continuous administration of the islands since 1833 and the islanders' "right to self-determination as set out in the UN Charter ". Argentina claims that, when it achieved independence in 1816, it acquired the Falklands from Spain. The incident of 1833 is particularly contentious; Argentina considers it proof of "Britain's usurpation" whereas

3848-574: The Environmental Impact Statement required "further discussion" and that any development and production program would need to be considered separately by the Executive Council. Development projects in education and sports have been funded by the Falklands government, without aid from the United Kingdom. The primary sector of the economy accounts for most of the Falkland Islands' gross domestic product, with

However, in May, 2024, newly elected Argentine president Javier Milei , expressed general acceptance and tolerance for British rule, for the time being, noting it could take decades for Argentina to gain control of the islands. Though asserting “We [will not] relinquish our sovereignty" over the islands, Milei said they would not "seek conflict with

4056-703: The Falkland Islands , which follows England's system , is free and compulsory for residents aged between 5 and 16 years. Primary education is available at Stanley, RAF Mount Pleasant (for children of service personnel) and a number of rural settlements. Secondary education is only available in Stanley, which offers boarding facilities and 12 subjects to General Certificate of Secondary Education (GCSE) level. Students aged 16 or older may study at colleges in England for their GCE Advanced Level or vocational qualifications. The Falkland Islands government pays for older students to attend institutions of higher education, usually in

4160-596: The Falkland Islands are independent ; no political parties exist on the islands. Since the 2013 general election , members of the Legislative Assembly have received a salary and are expected to work full-time and give up all previously held jobs or business interests. As a territory of the United Kingdom, the Falklands were part of the overseas countries and territories of the European Union until 2020 . The islands' judicial system, overseen by

4264-501: The Falkland Islands in prehistoric times, the islands were uninhabited when Europeans first explored them. European claims of discovery date back to the 16th century, but no consensus exists on whether early explorers sighted the Falklands or other islands in the South Atlantic. The first undisputed landing on the islands is attributed to English captain John Strong, who, en route to Peru and Chile 's littoral in 1690, explored

The Falklands remained uninhabited until the 1764 establishment of Port Louis on East Falkland by French captain Louis Antoine de Bougainville and the 1765 foundation of Port Egmont on Saunders Island by Captain John Byron ; the latter settlement being expanded by British captain John MacBride a year later. Whether or not the settlements were aware of each other's existence

4472-445: The Falklands as a garrison amid fears of a Japanese seizure of the archipelago. After the war ended, the Falklands economy was affected by declining wool prices and the political uncertainty resulting from the revived sovereignty dispute between the United Kingdom and Argentina. Simmering tensions between the UK and Argentina increased during the second half of the century, when Argentine President Juan Perón asserted sovereignty over

4576-499: The Falklands basin. Landmine clearance work restarted in 2009, in accordance with the UK's obligations under the Ottawa Treaty , and Sapper Hill Corral was cleared of mines in 2012, allowing access to an important historical landmark for the first time in 30 years. Argentina and the UK re-established diplomatic relations in 1990, but neither has agreed on the terms of future sovereignty discussions. The Falkland Islands are

4680-440: The Falklands became a Crown colony and Scottish settlers subsequently established an official pastoral community. Four years later, nearly everyone relocated to Port Jackson, considered a better location for the government, and merchant Samuel Lafone began a venture to encourage British colonisation. Stanley , as Port Jackson was soon renamed, officially became the seat of government in 1845. Early in its history, Stanley had

4784-409: The Falklands diversified from a sheep-based monoculture into an economy of tourism and, with the establishment of the Falklands exclusive economic zone , fisheries. The road network was also made more extensive, and the construction of RAF Mount Pleasant allowed access to long haul flights. Oil exploration also began in the 2010s, with indications of possible commercially exploitable deposits in

4888-399: The UK and mainland South America. Port Stanley Airport provides internal flights. Despite COVID-19 pandemic restrictions causing suspensions of flights from Santiago and São Paulo and prohibited cruise ship tourism, the economy of the islands remains stable and healthy. The Falkland Islands population is homogeneous, mostly descended from Scottish and Welsh immigrants who settled in

4992-514: The UK discounts it as a mere reassertion of its claim. In 2009, the British prime minister, Gordon Brown , had a meeting with the Argentine president, Cristina Fernández de Kirchner , and said that there would be no further talks over the sovereignty of the Falklands. In March 2013, the Falkland Islands held a referendum on its political status: 99.8% of votes cast favoured remaining a British overseas territory. Argentina does not recognise

5096-404: The United Kingdom" over them, preferring to resolve the dispute "within the framework of peace." The Falkland Islands have a land area of 4,700 sq mi (12,000 km ) and a coastline estimated at 800 mi (1,300 km). The archipelago consists of two main islands, West Falkland and East Falkland, and 776 smaller islands. The islands are predominantly mountainous and hilly, with

5200-477: The United Kingdom. Falklands culture is based on the cultural traditions of its British settlers but has also been influenced by Hispanic South America . Falklanders still use some terms and place names from the former Gaucho inhabitants. The Falklands' predominant and official language is English, with the foremost dialect being British English ; nonetheless, some inhabitants also speak Spanish. According to naturalist Will Wagstaff , "the Falkland Islands are

5408-431: The action of heat, pressure and permeating vapors, regenerating a rock mass without the production of fusion (at least on a large scale). It has been argued, however, that often there is extensive chemical change owing to the introduction of matter from the granite into the rocks surrounding it. The formation of new feldspar in the hornfelses is pointed out as evidence of this. While this felspathization may have occurred in

5512-542: The aligned linear depressions. In the margins of these depressions there is evidence of contact baking or hornfels formation adjacent to the once molten basalt dyke. Early explorers reported the remains of canoes on West Falkland but it is unclear whether it was a one way trip, or indeed if the canoes were not swept in from Patagonia . Captain John Strong of the Welfare made the first recorded landing on either of

5616-417: The alteration of igneous rocks . Although for the most part the constituent grains are too small to be determined by the unaided eye, there are often larger crystals ( porphyroblasts ) of cordierite , garnet or andalusite scattered through the fine matrix, and these may become very prominent on the weathered faces of the rock. The structure of the hornfels is very characteristic. Very rarely do any of

5720-611: The archipelago was visited only by fishing ships; its political status was undisputed until 1820, when Colonel David Jewett , an American privateer working for the United Provinces of the Río de la Plata , informed anchored ships about Buenos Aires ' 1816 claim to Spain's territories in the South Atlantic. Since the islands had no permanent inhabitants, in 1823 Buenos Aires granted German-born merchant Luis Vernet permission to conduct fishing activities and exploit feral cattle in

5824-509: The archipelago. The sovereignty dispute intensified during the 1960s, shortly after the United Nations passed a resolution on decolonisation which Argentina interpreted as favourable to its position. In 1965, the UN General Assembly passed Resolution 2065 , calling for both states to conduct bilateral negotiations to reach a peaceful settlement of the dispute. From 1966 until 1968, the UK confidentially discussed with Argentina

5928-400: The archipelago. Vernet settled at the ruins of Puerto Soledad in 1826, and accumulated resources on the islands until the venture was secure enough to bring settlers and form a permanent colony. Buenos Aires named Vernet military and civil commander of the islands in 1829, and he attempted to regulate sealing to stop the activities of foreign whalers and sealers. Vernet's venture lasted until

6032-500: The area without formal government. Vernet's deputy, the Scotsman Matthew Brisbane , returned to the islands that year to restore the business, but his efforts ended after, amid unrest at Port Louis, gaucho Antonio Rivero led a group of dissatisfied individuals to murder Brisbane and the settlement's senior leaders; survivors hid in a cave on a nearby island until the British returned and restored order. In 1840,

The Hornby Mountains , near Falkland Sound have experienced tectonic forces of uplift and folding which has inclined the quartzite beds of Stanley to the vertical. In West Falkland there are several dykes that cut the rocks of the western islands, but these dykes, unlike the previous ones, are chemically more unstable and have been eroded. The only indications of their existence are

6240-423: The coastline. The largest settlement is Port Howard on the east coast, which has an airstrip . Other settlements include Albemarle , Chartres , Dunnose Head , Fox Bay , Fox Bay West , Hill Cove , Port Stephens , and Roy Cove , most of which are linked by road and also have airstrips and harbours . In 1986, the population was 265, in 2001, it had fallen to 144 and rose to 160 in 2016. Because West Falkland

In April 1982 the Falklands War began when Argentine military forces invaded the Falklands and other British territories in the South Atlantic , briefly occupying them until

6552-406: The fishing industry alone contributing between 50% and 60% of annual GDP; agriculture also contributes significantly to GDP and employs about a tenth of the population. A little over a quarter of the workforce serves the Falkland Islands government, making it the archipelago's largest employer. Tourism, part of the service economy, has been spurred by increased interest in Antarctic exploration and

6656-721: The garrison from the islands, leaving a plaque claiming the Falklands for King George III. Spain's Viceroyalty of the Río de la Plata became the only formal presence in the territory. West Falkland was left abandoned, and Puerto Soledad became a penal colony. Amid the British invasions of the Río de la Plata during the Napoleonic Wars in Europe, the islands' governor evacuated the archipelago in 1806; Spain's remaining colonial garrison followed suit in 1811, except for gauchos and fishermen who remained voluntarily. Thereafter,

6760-403: The government has tried to contain, remove or exterminate foxes, rabbits and rats. Endemic land animals have been the most affected by introduced species, and several bird species have been extirpated from the larger islands. The extent of human impact on the Falklands is unclear, since there is little long-term data on habitat change. As of 2023 , the economy of the Falkland Islands is ranked

6864-474: The islands by French explorer Louis-Antoine de Bougainville in 1764. Bougainville, who founded the islands' first settlement, named the area after the port of Saint-Malo (the point of departure for his ships and colonists). The port, located in the Brittany region of western France, was named after St. Malo (or Maclou), the Christian evangelist who founded the city. In 1965, at the 20th session of

6968-404: The islands have had French, British, Spanish, and Argentine settlements. Britain reasserted its rule in 1833 , but Argentina maintains its claim to the islands. In April 1982, Argentine military forces invaded the islands . British administration was restored two months later at the end of the Falklands War . In a 2013 sovereignty referendum , almost all Falklanders voted in favour of remaining

7072-417: The islands' economic focus, with an increase in population as workers migrate from Camp. Fear of dependence on fishing licences and threats from overfishing , illegal fishing and fish market price fluctuations led to increased interest in oil drilling as an alternative source of revenue. As of 2001 exploration efforts had yet to find "exploitable reserves". By 2023, oil exploration was still proceeding off

7176-409: The islands' population decline has reduced, thanks to immigrants from the United Kingdom, Saint Helena , and Chile. In the 2012 census, a majority of residents listed their nationality as Falkland Islander (59 per cent), followed by British (29 per cent), Saint Helenian (9.8 per cent), and Chilean (5.4 per cent). A small number of Argentines also live on the islands. The Falkland Islands have

The governor acts on the advice of the islands' Executive Council , composed of the chief executive, the Director of Finance and three elected members of the Legislative Assembly (with the governor as chairman). The Legislative Assembly, a unicameral legislature , consists of the chief executive, the director of finance and eight members (five from Stanley and three from Camp ) elected to four-year terms by universal suffrage . All politicians in

He said: Although Strong recorded a lack of wood in the area, driftwood frequently washes up on Falkland beaches. This may be accounted for by the sheltered nature of Bold Cove. Strong named Falkland Sound , which gave its name to all the islands. While the first recorded landing on

Oil exploration, licensed by the Falkland Islands Government , remains controversial as a result of maritime disputes with Argentina. The name "Falkland Islands" comes from Falkland Sound , the strait that separates

7696-399: The main islands of the Falklands was on West Falkland, it was settled remarkably late. In 1867 there were no settlers on West Falkland. The government issued a proclamation offering leases of grazing stations on very moderate terms and in 1868 all the available land was occupied. Modern West Falkland is also home to two RAF Remote Radar Heads : Mount Alice, which is near Port Albemarle in

7800-487: The major exception being the depressed plains of Lafonia (a peninsula forming the southern part of East Falkland). The Falklands consists of continental crust fragments resulting from the break-up of Gondwana and the opening of the South Atlantic that began 130 million years ago. The islands are located in the South Atlantic Ocean , on the Patagonian Shelf , about 300 mi (480 km) east of Patagonia in southern Argentina. The Falklands' approximate location

7904-406: The matrix. The frequency with which this feature reappears in the less altered slates and hornfels is rather remarkable, especially as it seems certain that the spots are not always of the same nature or origin. Tourmaline hornfels are found sometimes near the margins of tourmaline granites; they are black with small needles of schorl that under the microscope are dark brown and richly pleochroic. As

8008-423: The metamorphic pressure-temperature space. The most common hornfels (the biotite hornfels) are dark-brown to black with a somewhat velvety luster owing to the abundance of small crystals of shining black mica . Also, most common hornfels have a black streak. The lime hornfels are often white, yellow, pale-green, brown and other colors. Green and dark-green are the prevalent tints of the hornfels produced by

8112-447: The minerals show crystalline form, but the small grains fit closely together like the fragments of a mosaic; they are usually of nearly equal dimensions. This has been called pflaster or pavement structure from the resemblance to rough pavement work. Each mineral may also enclose particles of the others; in quartz , for example, small crystals of graphite , biotite, iron oxides , sillimanite or feldspar may appear in great numbers. Often

8216-425: The original limestones. They are excessively variable in their mineralogical composition, and very often alternate in thin seams with biotite hornfels and indurated quartzites . When perfused with boric and fluoric vapors from the granite they may contain much axinite , fluorite and datolite , but the altiminous silicates are absent from these rocks. From diabases , basalts , andesites and other igneous rocks

8320-516: The original rocks (such as sandstone , shale , slate and limestone ) may have been more or less fissile owing to the presence of bedding or cleavage planes, this structure is effaced or rendered inoperative in the hornfels. Though many hornfels show vestiges of the original bedding, they break across this as readily as along it; in fact, they tend to separate into cubical fragments rather than into thin plates. Sheet minerals may be abundant but are aligned at random. Hornfels most commonly form in

8424-483: The pastures. Economic growth began only after the Falkland Islands Company , which bought out Lafone's failing enterprise in 1851, successfully introduced Cheviot sheep for wool farming, spurring other farms to follow suit. The high cost of importing materials, combined with the shortage of labour and consequent high wages, meant the ship repair trade became uncompetitive. After 1870 it declined as

8528-541: The prospect for a potential conflict between the Falkland Island's government and the British government. Nevertheless, the authority to approve oil development around the islands was said to rest solely with the Falkland Island's government. In November 2024, the Falkland's government Executive Council indicated that, while the public consultation process had been successfully concluded, "some matters" related to

8632-500: The pyroxene hornfels facies and sanidinite facies, the latter two being indistinguishable for this composition of protolith. For an ultramafic protolith, the albite-epidote facies is characterized by serpentine , talc , tremolite , and chlorite, giving way to forsterite , orthopyroxene, hornblende, chlorite, and characteristic minor aluminum spinel and magnetite in the hornblende facies, which in turn gives way to forsterite, orthopyroxene, augite, plagioclase, and aluminum spinel in

8736-470: The pyroxene hornfels facies. The sanidinite facies features quartz, plagioclase, sillimanite, cordierite, orthopyroxene, sapphirine , and aluminum spinel. For a calcareous protolith, the sequence is calcite , dolomite , quartz, tremolite, talc, and forsterite for the albite-epidote hornfels facies; calcite, dolomite, quartz, tremolite, diopside , and forsterite for the hornblende hornfels facies; calcite, quartz, diposide, forsterite, and wollastonite for

8840-499: The pyroxene hornfels facies. The sanidinite facies for this composition differs from the pyroxene hornfels facies only in the disappearance of aluminum spinel. For a pelitic protolith, the sequence is quartz , plagioclase, muscovite , chlorite, and cordierite in the albite-epidote facies; quartz, plagioclase, muscovite, biotite, cordierite, and andalusite in the hornblende hornfels facies; and quartz, plagioclase, orthoclase, andalusite, sillimanite , cordierite, and orthopyroxene in

8944-576: The rare striated caracara . There are also five different penguin species and a few of the largest albatross colonies on the planet. Endemic fish around the islands are primarily from the genus Galaxias . The Falklands are treeless and have a wind-resistant vegetation predominantly composed of a variety of dwarf shrubs . Virtually the entire land area of the islands is used as pasture for sheep. Introduced species include reindeer , hares, rabbits, Patagonian foxes , brown rats , and cats. Several of these species have harmed native flora and fauna, so

9048-641: The replacement of sail ships by steamships was accelerated by the low cost of coal in South America; by 1914, with the opening of the Panama Canal , the trade effectively ended. In 1881, the Falkland Islands became financially independent of Britain. For more than a century, the Falkland Islands Company dominated the trade and employment of the archipelago; in addition, it owned most housing in Stanley, which greatly benefited from

9152-423: The rock has been sufficient to efface most of the original structures and to replace the former minerals more-or-less completely by new ones. But crystallization has been hampered by the solid condition of the mass and the new minerals are formless and have been unable to reject impurities, but have grown around them. Clays , sedimentary slates and shales yield biotite hornfels in which the most conspicuous mineral

9256-566: The sale of fishing licences to "anybody wishing to fish within this zone". Since the end of the Falklands War in 1982, the islands' economic activity increasingly focused on oil field exploration and tourism. All large settlements are now connected by road and, since 2008, a ferry links West and East Falkland. The islands' major exports include wool, hides, venison, fish and squid; its main imports include fuel, building materials and clothing. The port settlement of Stanley has regained

9360-481: The same minerals as the hornfels, but have a schistose instead of a hornfels structure. Among these may be mentioned cordierite and sillimanite gneisses, andalusite and kyanite mica-schists, and those schistose calcite-silicate rocks that are known as cipolins . That these are sediments that have undergone thermal alteration is generally admitted, but the exact conditions under which they were formed are not always clear. The essential features of hornfelsing are ascribed to

9464-471: The sanidinite facies. The actual minerals present in each facies depends on the composition of the protolith . For a mafic protolith, the albite-epidote hornfels facies is characterized by albite and epidote or zoisite with minor actinolite and chlorite . This gives way to hornblende, plagioclase , pyroxene, and garnet in the hornblende hornfels facies, which in turn gives way to orthopyroxene , augite , plagioclase, and characteristic trace garnet in

9568-461: The shelf of the islands with a deepwater project led by Rockhopper Exploration . In 2023, Rockhopper (working with Tel Aviv-listed Navitas Petroleum) indicated that it had been presented with a new development plan for its Sea Lion project that aimed to cut costs and proceed in phases. It was stated that: "If realized, the new plan – with a total price tag of $ 2.2 billion – could lead to 80,000 barrels per day of production (up to 100,000 b/d at peak) via

9672-563: The south of the island, and Mount Byron in the north. In early 2007, the Falkland Islands Government awarded a contract to supply an east–west ferry to Workboat Services Ltd. The service runs between Port Howard and New Haven . West Falkland saw some activity during the Falklands War in 1982; Fox Bay , Port Howard and Pebble Island were all occupied by Argentine troops during the hostilities and were subjected to occasional shore bombardment and airstrikes by

9776-409: The territory after 1833. The Falkland-born population are also descended from English and French people , Gibraltarians , Scandinavians, and South Americans. The 2016 census indicated that 43% of residents were born on the archipelago, with foreign-born residents assimilated into local culture. The legal term for the right of residence is "belonging to the islands". In 1983, full British citizenship

9880-445: The top of the cliffs is a single wooden hut locally referred to as Uncle Tom's Cabin. The beaches are a habitat for elephant seals and are unpolluted save for the occasional piece of wreckage. Most of the layers of West Falkland and its surrounding islands are slightly inclined from the horizontal. This inclination shows different types of rocks in different places. The quartzites of Port Stephens and Stanley are more resistant than

9984-810: The tourmaline contains boron , there must have been some permeation of vapors from the granite into the sediments. Rocks of this group are often seen in the Cornish tin -mining districts, especially near the lodes. A second great group of hornfels are the calc–silicate hornfels that arise from the thermal alteration of impure limestone . The purer beds recrystallize as marbles , but where there has been originally an admixture of sand or clay lime-bearing silicates are formed, such as diopside , epidote , garnet , sphene , vesuvianite and scapolite ; with these phlogopite , various feldspars, pyrites , quartz and actinolite often occur. These rocks are fine-grained, and though often banded, are tough and much harder than

10088-526: The transfer of the Falklands, assuming its judgement would be accepted by the islanders. An agreement on trade ties between the archipelago and the mainland was reached in 1971 and, consequently, Argentina built a temporary airfield at Stanley in 1972. Nonetheless, Falklander dissent, as expressed by their strong lobby in the UK Parliament , and tensions between the UK and Argentina effectively limited sovereignty negotiations until 1977. Concerned at

10192-595: The two main islands. The name "Falkland" was applied to the channel by John Strong , captain of an English expedition that landed on the islands in 1690. Strong named the strait in honour of Anthony Cary, 5th Viscount Falkland , the Treasurer of the Navy who sponsored his journey. The Viscount's title originates from the town of Falkland , Scotland—the town's name probably comes from a Gaelic term referring to an "enclosure" ( lann ), but it could less plausibly be from

10296-645: The two main rivers, the Warrah and the Chartres . In the 19th century as today, indigenous land fauna was very scanty. A small wolf, the warrah , the loup-renard of Louis Antoine de Bougainville , is extinct, the last having been seen about 1875 on West Falkland. It is commemorated in the name of one of the island's rivers – the Warrah River – and the settlement of Fox Bay . Some herds of cattle and horses ran wild; but these were introduced by settlers as were

10400-432: The whole of the grains are rendered semi-opaque in this way. The minutest crystals may show traces of crystalline outlines; undoubtedly they are of new formation and have originated in situ . This leads us to believe that the whole rock has been recrystallized at a high temperature and in the solid state so that there was little freedom for the mineral molecules to build up well-individualized crystals. The regeneration of

10504-440: The wild hogs, the numerous rabbits and the less common hares. All these have greatly declined in numbers, being profitably replaced by sheep. The southernmost point of West Falkland is Cape Meredith , and the most south-westerly point is Calm Head . On the southerly side lie high cliffs with an abundance of seabirds. To the west are some white sandy beaches with clean water and rolling sand dunes with tall grass. Set just back from

10608-546: The wool trade with the UK. In the first half of the 20th century, the Falklands served an important role in Britain's territorial claims to subantarctic islands and a section of Antarctica. The Falklands governed these territories as the Falkland Islands Dependencies starting in 1908 and retained them until their dissolution in 1985. The Falklands also played a minor role in the two world wars as

10712-418: Was given to Falkland Islanders under the British Nationality (Falkland Islands) Act 1983 . A significant population decline affected the archipelago in the 20th century, with many young islanders moving overseas in search of education, a modern lifestyle, and better job opportunities, particularly to the British city of Southampton , which came to be known in the islands as "Stanley North". In recent years,

10816-466: Was thought that Mount Robinson at 695 metres (2,280 ft) above sea level was the highest point. However, a later survey found that Mount Adam was higher. At this, the Argentines transferred the name Monte Independencia from Mount Robinson to Mount Adam. The major industry on the island is sheep farming , while it is also known for its penguin and cormorant colonies. Fishing is also popular in
