103-651: The Scarborough News is a weekly newspaper distributed in and around the Scarborough area in North Yorkshire , England. It was launched on 31 May 2012 as a relaunch of the former daily newspaper, the Scarborough Evening News , and incorporates information from the former Saturday edition of the Filey & Hunmanby Mercury . It is a 'bumper' edition (136 pages), as news for seven days that
206-455: A Mohs hardness of 2 to 4, dense limestone can have a crushing strength of up to 180 MPa . For comparison, concrete typically has a crushing strength of about 40 MPa. Although limestones show little variability in mineral composition, they show great diversity in texture. However, most limestone consists of sand-sized grains in a carbonate mud matrix. Because limestones are often of biological origin and are usually composed of sediment that
309-463: A bloom of cyanobacteria or microalgae . However, stable isotope ratios in modern carbonate mud appear to be inconsistent with either of these mechanisms, and abrasion of carbonate grains in high-energy environments has been put forward as a third possibility. Formation of limestone has likely been dominated by biological processes throughout the Phanerozoic , the last 540 million years of
412-434: A carbonate rock outcrop can be estimated in the field by etching the surface with dilute hydrochloric acid. This etches away the calcite and aragonite, leaving behind any silica or dolomite grains. The latter can be identified by their rhombohedral shape. Crystals of calcite, quartz , dolomite or barite may line small cavities ( vugs ) in the rock. Vugs are a form of secondary porosity, formed in existing limestone by
515-616: A central quartz grain or carbonate mineral fragment. These likely form by direct precipitation of calcium carbonate onto the ooid. Pisoliths are similar to ooids, but they are larger than 2 mm in diameter and tend to be more irregular in shape. Limestone composed mostly of ooids is called an oolite or sometimes an oolitic limestone . Ooids form in high-energy environments, such as the Bahama platform, and oolites typically show crossbedding and other features associated with deposition in strong currents. Oncoliths resemble ooids but show
618-449: A change in environment that increases the solubility of calcite. Dense, massive limestone is sometimes described as "marble". For example, the famous Portoro "marble" of Italy is actually a dense black limestone. True marble is produced by recrystallization of limestone during regional metamorphism that accompanies the mountain building process ( orogeny ). It is distinguished from dense limestone by its coarse crystalline texture and
721-949: A composition reflecting the organisms that produced them and the environment in which they were produced. Low-magnesium calcite skeletal grains are typical of articulate brachiopods , planktonic (free-floating) foraminifera, and coccoliths . High-magnesium calcite skeletal grains are typical of benthic (bottom-dwelling) foraminifera, echinoderms , and coralline algae . Aragonite skeletal grains are typical of molluscs , calcareous green algae , stromatoporoids , corals , and tube worms . The skeletal grains also reflect specific geological periods and environments. For example, coral grains are more common in high-energy environments (characterized by strong currents and turbulence) while bryozoan grains are more common in low-energy environments (characterized by quiet water). Ooids (sometimes called ooliths) are sand-sized grains (less than 2mm in diameter) consisting of one or more layers of calcite or aragonite around
824-412: A considerable fraction of the limestone bed. At depths greater than 1 km (0.62 miles), burial cementation completes the lithification process. Burial cementation does not produce stylolites. When overlying beds are eroded, bringing limestone closer to the surface, the final stage of diagenesis takes place. This produces secondary porosity as some of the cement is dissolved by rainwater infiltrating
927-483: A drop of dilute hydrochloric acid is dropped on it. Dolomite is also soft but reacts only feebly with dilute hydrochloric acid, and it usually weathers to a characteristic dull yellow-brown color due to the presence of ferrous iron. This is released and oxidized as the dolomite weathers. Impurities (such as clay , sand, organic remains, iron oxide , and other materials) will cause limestones to exhibit different colors, especially with weathered surfaces. The makeup of
1030-637: A few million years, as this is the most stable form of calcium carbonate. Ancient carbonate formations of the Precambrian and Paleozoic contain abundant dolomite, but limestone dominates the carbonate beds of the Mesozoic and Cenozoic . Modern dolomite is quite rare. There is evidence that, while the modern ocean favors precipitation of aragonite, the oceans of the Paleozoic and middle to late Cenozoic favored precipitation of calcite. This may indicate
1133-455: A few thousand years. As rainwater mixes with groundwater, aragonite and high-magnesium calcite are converted to low-calcium calcite. Cementing of thick carbonate deposits by rainwater may commence even before the retreat of the sea, as rainwater can infiltrate over 100 km (60 miles) into sediments beneath the continental shelf. As carbonate sediments are increasingly deeply buried under younger sediments, chemical and mechanical compaction of

#17327729923671236-490: A high percentage of the mineral dolomite , CaMg(CO 3 ) 2 . Magnesian limestone is an obsolete and poorly-defined term used variously for dolomite, for limestone containing significant dolomite ( dolomitic limestone ), or for any other limestone containing a significant percentage of magnesium . Most limestone was formed in shallow marine environments, such as continental shelves or platforms , though smaller amounts were formed in many other environments. Much dolomite
1339-535: A housing development in Eastfield , Scarborough, revealed a Roman luxury villa, religious sanctuary, or combination of both. The building layout is unique in Britain and extends over an area of about the size of two tennis courts. It included a bathhouse and a cylindrical tower with rooms radiating from it. The buildings were “designed by the highest-quality architects in northern Europe in the era and constructed by
1442-458: A licence to go into a large-scale commercial operation from 2019. SeaGrown have an intent to move into the bioplastics market. The tourism trade continues to be a major part of the local economy with Scarborough being the second most-visited destination in England by British holidaymakers. While weekend and mid-week-break trade are tending to replace the traditional week-long family holiday,
1545-435: A limestone sample except in thin section and are less common in ancient limestones, possibly because compaction of carbonate sediments disrupts them. Limeclasts are fragments of existing limestone or partially lithified carbonate sediments. Intraclasts are limeclasts that originate close to where they are deposited in limestone, while extraclasts come from outside the depositional area. Intraclasts include grapestone , which
1648-471: A lower Mg/Ca ratio in the ocean water of those times. This magnesium depletion may be a consequence of more rapid sea floor spreading , which removes magnesium from ocean water. The modern ocean and the ocean of the Mesozoic have been described as "aragonite seas". Most limestone was formed in shallow marine environments, such as continental shelves or platforms . Such environments form only about 5% of
1751-525: A lower diversity of organisms and a greater fraction of silica and clay minerals characteristic of marls . The Green River Formation is an example of a prominent freshwater sedimentary formation containing numerous limestone beds. Freshwater limestone is typically micritic. Fossils of charophyte (stonewort), a form of freshwater green algae, are characteristic of these environments, where the charophytes produce and trap carbonates. Limestones may also form in evaporite depositional environments . Calcite
1854-523: A mechanism for dolomitization, with one 2004 review paper describing it bluntly as "a myth". Ordinary seawater is capable of converting calcite to dolomite, if the seawater is regularly flushed through the rock, as by the ebb and flow of tides (tidal pumping). Once dolomitization begins, it proceeds rapidly, so that there is very little carbonate rock containing mixed calcite and dolomite. Carbonate rock tends to be either almost all calcite/aragonite or almost all dolomite. About 20% to 25% of sedimentary rock
1957-449: A mix of quality hotels and flats. The ITV television drama The Royal and its recent spin-off series, The Royal Today were both filmed in the area. The South Bay has the largest illuminated 'star disk' anywhere in the UK. It is 85 ft (26 m) across and fitted with subterranean lights representing the 42 brightest stars and major constellations that can be seen from Scarborough in
2060-698: A more pedestrian-friendly promenade, street lighting and seating. The town was badly damaged in a 98 plane bombing raid by the Luftwaffe during the Second World War , on 18 March 1941. Twenty eight civilians were killed and hundreds were injured and over 1,400 buildings were damaged. The South Cliff Promenade above the Spa and South Cliff Gardens has wide views of the South Bay and old town. Its splendid Regency and Victorian terraces are still intact, with
2163-626: A natural space for picnics, fishing and walkers. In 2012 a new snack bar was built alongside the Mere. The lake is now part of the Oliver's Mount Country Park and the Hispaniola now sails out of Scarborough harbour during the summer season. Surrounding the River Derwent as it flows into the sea are high hills with tall, dense grasses and fertile soil, due to the stream ' Sea Cut ' leading from

#17327729923672266-589: A new boat house was added in 2018. For many years a mock maritime battle (based on the Battle of the River Plate ) has been regularly re-enacted on the boating lake with large model boats and fireworks throughout the summer holiday season. Northstead Manor Gardens include the North Bay Railway and three other attractions: a water chute, a boating lake with boats for hire during the summer season and
2369-539: A number of Royal Navy vessels, including HMS Apollo , HMS Fearless and HMS Duncan . The town has an Anglican church, St Martin-on-the-Hill , built in 1862–63 as the parish church of South Cliff. It contains works by Dante Gabriel Rossetti , William Morris , Edward Burne-Jones and Ford Madox Brown . A young Malton architect, John Gibson, designed the Crown Spa Hotel , Scarborough's first purpose-built hotel. Notable Georgian structures include
2472-448: A plausible source of mud. Another possibility is direct precipitation from the water. A phenomenon known as whitings occurs in shallow waters, in which white streaks containing dispersed micrite appear on the surface of the water. It is uncertain whether this is freshly precipitated aragonite or simply material stirred up from the bottom, but there is some evidence that whitings are caused by biological precipitation of aragonite as part of
2575-449: A radial rather than layered internal structure, indicating that they were formed by algae in a normal marine environment. Peloids are structureless grains of microcrystalline carbonate likely produced by a variety of processes. Many are thought to be fecal pellets produced by marine organisms. Others may be produced by endolithic (boring) algae or other microorganisms or through breakdown of mollusc shells. They are difficult to see in
2678-642: A smaller market on the South Bay. Boyes (based on the town's outskirts in Eastfield ) is a discount department store chain which has over 70 stores across principally the north of England and in the English East Midlands with a flagship shop on Queen Street. Manufacturers based in Scarborough include the Plaxton Company (a division of Alexander Dennis ) which has been building coaches and buses since 1907. Sirius Minerals , which

There is no archaeological evidence to support this claim, which was made during the 1960s as part of a pageant of Scarborough events. The claim is based on a fragment of an Icelandic Saga . However, due to coastal erosion over
2884-405: A theme of time: four towers represent the seasons, 12 floors the months, 52 chimneys the weeks and the original 365 bedrooms represented the days of the year. A blue plaque outside the hotel marks where the novelist Anne Brontë died in 1849. She was buried in the graveyard of St Mary's Church by the castle. An amount of 20th century architecture exists within the main shopping district and in
2987-560: Is also favored on the seaward margin of shelves and platforms, where there is upwelling deep ocean water rich in nutrients that increase organic productivity. Reefs are common here, but when lacking, ooid shoals are found instead. Finer sediments are deposited close to shore. The lack of deep sea limestones is due in part to rapid subduction of oceanic crust, but is more a result of dissolution of calcium carbonate at depth. The solubility of calcium carbonate increases with pressure and even more with higher concentrations of carbon dioxide, which
3090-482: Is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium . Calcite in limestone is divided into low-magnesium and high-magnesium calcite, with the dividing line placed at a composition of 4% magnesium. High-magnesium calcite retains the calcite mineral structure, which is distinct from dolomite. Aragonite does not usually contain significant magnesium. Most limestone
3193-402: Is carbonate rock, and most of this is limestone. Limestone is found in sedimentary sequences as old as 2.7 billion years. However, the compositions of carbonate rocks show an uneven distribution in time in the geologic record. About 95% of modern carbonates are composed of high-magnesium calcite and aragonite. The aragonite needles in carbonate mud are converted to low-magnesium calcite within

3296-474: Is clusters of peloids cemented together by organic material or mineral cement. Extraclasts are uncommon, are usually accompanied by other clastic sediments, and indicate deposition in a tectonically active area or as part of a turbidity current . The grains of most limestones are embedded in a matrix of carbonate mud. This is typically the largest fraction of an ancient carbonate rock. Mud consisting of individual crystals less than 5 μm (0.20 mils) in length
3399-416: Is commonly white to gray in color. Limestone that is unusually rich in organic matter can be almost black in color, while traces of iron or manganese can give limestone an off-white to yellow to red color. The density of limestone depends on its porosity, which varies from 0.1% for the densest limestone to 40% for chalk. The density correspondingly ranges from 1.5 to 2.7 g/cm . Although relatively soft, with
3502-420: Is controlled largely by the amount of dissolved carbon dioxide ( CO 2 ) in the water. This is summarized in the reaction: Increases in temperature or decreases in pressure tend to reduce the amount of dissolved CO 2 and precipitate CaCO 3 . Reduction in salinity also reduces the solubility of CaCO 3 , by several orders of magnitude for fresh water versus seawater. Near-surface water of
3605-545: Is converted to low-magnesium calcite. Diagenesis is the likely origin of pisoliths , concentrically layered particles ranging from 1 to 10 mm (0.039 to 0.394 inches) in diameter found in some limestones. Pisoliths superficially resemble ooids but have no nucleus of foreign matter, fit together tightly, and show other signs that they formed after the original deposition of the sediments. Silicification occurs early in diagenesis, at low pH and temperature, and contributes to fossil preservation. Silicification takes place through
3708-503: Is deposited close to where it formed, classification of limestone is usually based on its grain type and mud content. Most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera . These organisms secrete structures made of aragonite or calcite, and leave these structures behind when they die. Other carbonate grains composing limestones are ooids , peloids , and limeclasts ( intraclasts and extraclasts [ ca ] ). Skeletal grains have
3811-460: Is described as coquinite . Chalk is a soft, earthy, fine-textured limestone composed of the tests of planktonic microorganisms such as foraminifera, while marl is an earthy mixture of carbonates and silicate sediments. Limestone forms when calcite or aragonite precipitate out of water containing dissolved calcium, which can take place through both biological and nonbiological processes. The solubility of calcium carbonate ( CaCO 3 )
3914-617: Is described as micrite . In fresh carbonate mud, micrite is mostly small aragonite needles, which may precipitate directly from seawater, be secreted by algae, or be produced by abrasion of carbonate grains in a high-energy environment. This is converted to calcite within a few million years of deposition. Further recrystallization of micrite produces microspar , with grains from 5 to 15 μm (0.20 to 0.59 mils) in diameter. Limestone often contains larger crystals of calcite, ranging in size from 0.02 to 0.1 mm (0.79 to 3.94 mils), that are described as sparry calcite or sparite . Sparite
4017-580: Is developing a potash mine near Whitby, has its headquarters in Scarborough. McCain Foods has a factory in the town for over 50 years, and sponsored the previous football stadium . Scarborough power station supplied electricity to the town and the surrounding area from 1893 to 1958. It was owned and operated by the Scarborough Electric Supply Company Limited from 1893 to 1925, then by Scarborough Corporation until
4120-462: Is distinguished from micrite by a grain size of over 20 μm (0.79 mils) and because sparite stands out under a hand lens or in thin section as white or transparent crystals. Sparite is distinguished from carbonate grains by its lack of internal structure and its characteristic crystal shapes. Geologists are careful to distinguish between sparite deposited as cement and sparite formed by recrystallization of micrite or carbonate grains. Sparite cement
4223-403: Is far above sea level compared to the immediate coastline, where the climate is likely slightly milder year round. Scarborough's fishing industry is still active, though much reduced in size. The working harbour is home to a fish market including a shop and wooden stalls where fresh, locally-caught seafood can be purchased by the public.

On 5 June 1993, Scarborough made international headlines when a landslip caused part of the Holbeck Hall Hotel , along with its gardens, to fall into the sea. Although the slip was shored up with rocks and the land has long since grassed over, evidence of the cliff's collapse remains clearly visible from The Esplanade, near Shuttleworth Gardens. Scarborough has been affiliated with
4429-560: Is one of the first minerals to precipitate in marine evaporites. Most limestone is formed by the activities of living organisms near reefs, but the organisms responsible for reef formation have changed over geologic time. For example, stromatolites are mound-shaped structures in ancient limestones, interpreted as colonies of cyanobacteria that accumulated carbonate sediments, but stromatolites are rare in younger limestones. Organisms precipitate limestone both directly as part of their skeletons, and indirectly by removing carbon dioxide from
4532-473: Is otherwise chemically fairly pure, with clastic sediments (mainly fine-grained quartz and clay minerals ) making up less than 5% to 10% of the composition. Organic matter typically makes up around 0.2% of a limestone and rarely exceeds 1%. Limestone often contains variable amounts of silica in the form of chert or siliceous skeletal fragments (such as sponge spicules, diatoms , or radiolarians ). Fossils are also common in limestone. Limestone
4635-472: Is produced by decaying organic matter settling into the deep ocean that is not removed by photosynthesis in the dark depths. As a result, there is a fairly sharp transition from water saturated with calcium carbonate to water unsaturated with calcium carbonate, the lysocline , which occurs at the calcite compensation depth of 4,000 to 7,000 m (13,000 to 23,000 feet). Below this depth, foraminifera tests and other skeletal particles rapidly dissolve, and
4738-518: Is secondary dolomite, formed by chemical alteration of limestone. Limestone is exposed over large regions of the Earth's surface, and because limestone is slightly soluble in rainwater, these exposures often are eroded to become karst landscapes. Most cave systems are found in limestone bedrock. Limestone has numerous uses: as a chemical feedstock for the production of lime used for cement (an essential component of concrete ), as aggregate for

Diagenesis may include conversion of limestone to dolomite by magnesium-rich fluids. There is considerable evidence of replacement of limestone by dolomite, including sharp replacement boundaries that cut across bedding. The process of dolomitization remains an area of active research, but possible mechanisms include exposure to concentrated brines in hot environments ( evaporative reflux ) or exposure to diluted seawater in delta or estuary environments ( Dorag dolomitization ). However, Dorag dolomitization has fallen into disfavor as

Folk developed a classification system that places primary emphasis on the detailed composition of grains and interstitial material in carbonate rocks . Based on composition, there are three main components: allochems (grains), matrix (mostly micrite), and cement (sparite). The Folk system uses two-part names;
7622-429: The geologic record are called bioherms . Many are rich in fossils, but most lack any connected organic framework like that seen in modern reefs. The fossil remains are present as separate fragments embedded in ample mud matrix. Much of the sedimentation shows indications of occurring in the intertidal or supratidal zones, suggesting sediments rapidly fill available accommodation space in the shelf or platform. Deposition
7725-417: The headland and granted the town charters in 1155 and 1163, permitting a market on the sands and establishing rule by burgesses . Edward II granted Scarborough Castle to his favourite, Piers Gaveston . The castle was subsequently besieged by forces led by the barons Percy, Warenne, Clifford and Pembroke. Gaveston was captured and taken to Oxford and thence to Warwick Castle for execution. In 1318,
7828-477: The hospital but promised to maintain the site's Accident and Emergency department. A new £47 million Emergency Department is under construction and is due to open in early 2024. The town's built-up area population was 61,749 in the 2011 UK census , most of the Newby and Scalby civil parish population was included in the area. Its unparished area has a larger population than the rest of parished areas of
7931-411: The main tourist area, with a sandy beach, cafés, amusements, arcades, theatres and entertainment facilities. The modern commercial town centre has migrated 440 yd (400 m) north-west of the harbour area and 100 ft (30 m) above it and contains the transport hubs, main services, shopping and nightlife. The harbour has undergone major regeneration including the new Albert Strange Pontoons,
8034-525: The nationalisation of utilities by the Attlee ministry in 1948. The coal-fired power station had an electricity generating capacity of 7 MW prior to its closure in October 1958. Creative industries have been cited as playing a vital role in the regeneration of Scarborough; a report in 2005 estimated that they comprised 19% of the town's economy. They were also a major focus of Scarborough's winning entry in
8137-799: The newspaper was to be re-launched as a weekly publication, along with three other Johnston Press regional newspapers, joining two dozen other titles across the country that had made the transition. The organisation has announced its plans to include extensive daily online publishing, coupled with iPad technology. Editors: Ed Asquith (2003–2018), Paul Napier (2000–2003), David Penman (1993–2000), Neil Speight (1990–1993), John Bird (1986–1990), Ray Lazenby (1966–1986) Awards – As The Scarborough Evening News : Yorkshire Regional Newspaper of Year 2003; The JP Best Daily Newspaper Sales Performance, and Community Initiative runner-up 2004; Yorkshire Press Awards Best Front Page runner-up 2005; Race for Life – national best media coverage 2005; Yorkshire Press Awards Campaign of
8240-453: The northern skies. To the south-west of the town, beside the York to Scarborough railway line , is an ornamental lake known as Scarborough Mere . In the 20th century the Mere was a popular park, with rowing boats, canoes and a miniature pirate ship – the Hispaniola – on which passengers were taken to 'Treasure Island' to dig for doubloons. Since the late 1990s the Mere has been redesigned as
8343-410: The ocean basins, but limestone is rarely preserved in continental slope and deep sea environments. The best environments for deposition are warm waters, which have both a high organic productivity and increased saturation of calcium carbonate due to lower concentrations of dissolved carbon dioxide. Modern limestone deposits are almost always in areas with very little silica-rich sedimentation, reflected in
8446-474: The oldest operational diesel-hydraulic locomotive in the world. Neptune was built in 1931 by Hudswell Clarke of Leeds and is appropriately numbered 1931. The most striking feature of the town's geography is the high rocky promontory pointing eastward into the North Sea with Scarborough Castle on the top. The castle was bombarded by the German warships SMS Derfflinger and SMS Von der Tann in
8549-468: The open-air theatre . The water chute is now grade II listed and is one of the oldest surviving water chutes in Britain, with the ride of today being the same as when it was opened in the 1930s. The North Bay Railway is a miniature railway running from near Peasholm Park, through Northstead Manor Gardens to the Sea Life Centre at Scalby Mills. The North Bay Railway has what is believed to be
8652-426: The reaction: Fossils are often preserved in exquisite detail as chert. Cementing takes place rapidly in carbonate sediments, typically within less than a million years of deposition. Some cementing occurs while the sediments are still under water, forming hardgrounds . Cementing accelerates after the retreat of the sea from the depositional environment, as rainwater infiltrates the sediment beds, often within just
8755-482: The relative purity of most limestones. Reef organisms are destroyed by muddy, brackish river water, and carbonate grains are ground down by much harder silicate grains. Unlike clastic sedimentary rock, limestone is produced almost entirely from sediments originating at or near the place of deposition. Limestone formations tend to show abrupt changes in thickness. Large moundlike features in a limestone formation are interpreted as ancient reefs , which when they appear in
8858-460: The rock. The Dunham scheme is more useful for hand samples because it is based on texture, not the grains in the sample. A revised classification was proposed by Wright (1992). It adds some diagenetic patterns to the classification scheme. Travertine is a term applied to calcium carbonate deposits formed in freshwater environments, particularly waterfalls , cascades and hot springs . Such deposits are typically massive, dense, and banded. When
8961-479: The sediments increases. Chemical compaction takes place by pressure solution of the sediments. This process dissolves minerals from points of contact between grains and redeposits it in pore space, reducing the porosity of the limestone from an initial high value of 40% to 80% to less than 10%. Pressure solution produces distinctive stylolites , irregular surfaces within the limestone at which silica-rich sediments accumulate. These may reflect dissolution and loss of
9064-662: The sediments of the ocean floor abruptly transition from carbonate ooze rich in foraminifera and coccolith remains ( Globigerina ooze) to silicic mud lacking carbonates. In rare cases, turbidites or other silica-rich sediments bury and preserve benthic (deep ocean) carbonate deposits. Ancient benthic limestones are microcrystalline and are identified by their tectonic setting. Fossils typically are foraminifera and coccoliths. No pre-Jurassic benthic limestones are known, probably because carbonate-shelled plankton had not yet evolved. Limestones also form in freshwater environments. These limestones are not unlike marine limestone, but have
9167-495: The south of the town. This gave birth to Scarborough Spa , and Dr Robert Wittie's book about the spa waters published in 1660 attracted a flood of visitors to the town. Scarborough Spa became Britain 's first seaside resort, though the first rolling bathing machines were not reported on the sands until 1735. It was a popular getaway destination for the wealthy of London, such as the bookseller Andrew Millar and his family. Their son Andrew junior died there in 1750. The coming of
9270-405: The steam drifter Ascendent caught a 560 lb (250 kg) tunny ( Atlantic bluefin tuna ) and a Scarborough showman awarded the crew 50 shillings so he could exhibit it as a tourist attraction. Big-game tunny fishing off Scarborough effectively started in 1930 when Lorenzo "Lawrie" Mitchell–Henry, landed a tunny caught on rod and line weighing 560 lb (250 kg). A gentlemen's club,
9373-525: The time during the 19th century as it expanded away from its historic centre into a coastal spa resort. A notable landmark in the town is the Grand Hotel on St Nicholas Cliff. Designed by Cuthbert Brodrick of Hull, it was completed in 1867; at the time of its opening, it was the largest hotel and the largest brick structure in Europe. It uses local yellow brickwork with red detailing and is based around
9476-410: The town lies around the harbour and is protected by a rocky headland which extends into the North Sea . The town has fishing and service industries, including a growing digital and creative economy, as well as being a tourist destination. Residents of the town are known as Scarborians. Scarborough was founded by Danes in the 10th century, when Thorgil (also known as Skarthi, meaning 'hare-lip') built
9579-571: The town was burnt by the Scots , under Sir James Douglas following the Capture of Berwick upon Tweed . In the Middle Ages , Scarborough Fair , permitted in a royal charter of 1253, held a six-week trading festival attracting merchants from all over Europe. It ran from Assumption Day , 15 August, until Michaelmas Day , 29 September. The fair continued to be held for 500 years, from the 13th to
9682-504: The town was the winner of the 'Great Town Award', as nominated by the Academy of Urbanism, beating Chester and Cambridge respectively. Scarborough Hospital is the local district general NHS hospital. It is run by the York and Scarborough Teaching Hospitals NHS Foundation Trust , and is the largest employer in the area employing over 2,400 staff. A review of acute healthcare in the town in 2019 identified problems recruiting staff at
9785-521: The town; these also link it to other major towns and cities: Scarborough has 25 main bus routes, operated by Scarborough Locals , Arriva North East , Shoreline Suncruisers and Yorkshire Coastliner . These link the town centre with its suburbs, the North York Moors and local towns and cities such as Bridlington , Whitby , York , Hull , Middlesbrough and Leeds . The town is also served by two Park and Ride services, with locations on
9888-618: The two newspapers continued up to 1921 when the Evening News bought the Daily Post . The newspaper gave a local slant on the day's news , plus a look at headlines across the United Kingdom and the world. When first published, it was one of six newspapers serving the area. Published six times a week Monday–Saturday, it served a 20-mile (30 km) radius of Scarborough, with a core radius of 12 miles (20 km). It
9991-533: The water by photosynthesis and thereby decreasing the solubility of calcium carbonate. Limestone shows the same range of sedimentary structures found in other sedimentary rocks. However, finer structures, such as lamination , are often destroyed by the burrowing activities of organisms ( bioturbation ). Fine lamination is characteristic of limestone formed in playa lakes , which lack the burrowing organisms. Limestones also show distinctive features such as geopetal structures , which form when curved shells settle to
10094-553: The water. Although ooids likely form through purely inorganic processes, the bulk of CaCO 3 precipitation in the oceans is the result of biological activity. Much of this takes place on carbonate platforms . The origin of carbonate mud, and the processes by which it is converted to micrite, continue to be a subject of research. Modern carbonate mud is composed mostly of aragonite needles around 5 μm (0.20 mils) in length. Needles of this shape and composition are produced by calcareous algae such as Penicillus , making this
10197-424: The wider Borough of Scarborough , including the coastal towns of Whitby and Filey . The borough as a whole has a population of around 108,000; during the peak season, tourism can double these figures. 7.5% of the population are aged over 60, compared with an average of 20.9% nationally. Only 21.9% of the population are aged between 20 and 39, compared to 28.1% nationally. Scarborough has four major roads serving
10300-641: The years, evidence may have been lost to the sea. In the 4th century, there was briefly a Roman signal station on Scarborough headland, and there is evidence of earlier settlements, during the Stone Age and Bronze Age . Any settlement between the fifth and ninth centuries would have been burned to the ground by a band of Vikings under Tostig Godwinson (a rival of Thorgils Skarthi ), Lord of Falsgrave, or Harald III of Norway . These periodic episodes of destruction and massacre means that very little evidence of settlement during this period remained to be recorded in
10403-648: Was also available in Whitby , alongside the Whitby Gazette , and in many other towns and villages in the borough of Scarborough . For many years, the Saturday edition of the newspaper was titled The Mercury . In March 2006, the press at the Scarborough Evening News office in Scarborough was closed, ending printing in the town going back 150 years. In May 2012 it was announced that
10506-416: Was likely deposited in pore space between grains, suggesting a high-energy depositional environment that removed carbonate mud. Recrystallized sparite is not diagnostic of depositional environment. Limestone outcrops are recognized in the field by their softness (calcite and aragonite both have a Mohs hardness of less than 4, well below common silicate minerals) and because limestone bubbles vigorously when
10609-484: Was spread over six days (including the former Saturday Mercury edition) now has to be condensed into a weekly issue. It is part of Yorkshire Regional Newspapers Ltd., which is owned by National World . The Scarborough Evening News was first published in 1882. At that time, the paper had a major rival in the Scarborough Daily Post , which had appeared six years earlier in 1876. The rivalry between
