30-594: Santurce can refer to: Santurce ( Basque : Santurtzi ), a town near Bilbao, the Basque Country, Spain; the original town with the name Santurce, Argentina , a town in Santa Fe, Argentina. Santurce, San Juan, Puerto Rico , a barrio of the municipio of San Juan, Puerto Rico [REDACTED] Topics referred to by the same term This disambiguation page lists articles about distinct geographical locations with

60-403: A geologic map view that point in the direction of plunge . A plunging anticline has a hinge that is not parallel to the earth's surface. All anticlines and synclines have some degree of plunge. Periclinal folds are a type of anticlines that have a well-defined, but curved hinge line and are doubly plunging and thus elongate domes . Folds in which the limbs dip toward the hinge and display

90-479: A high rate of compression and seismic activity due to the converging San Andreas Fault. As a result, the Ventura anticline rises at a rate of 5 mm/year with the adjacent Ventura Basin converging at a rate of about 7–10 mm/year. The anticline is composed of a series of sandstone rock beds and an impermeable rock cap under which vast reserves of oil and gas are trapped. Eight different oil bearing zones along

120-457: A more U-like shape are called synclines . They usually flank the sides of anticlines and display opposite characteristics. A syncline's oldest rock strata are in its outer limbs; the rocks become progressively younger toward its hinge. A monocline is a bend in the strata resulting in a local steepening in only one direction of dip. Monoclines have the shape of a carpet draped over a stairstep. An anticline that has been more deeply eroded in

150-738: Is a large anticline in which a series of minor anticlinal folds are superimposed. Examples include the Late Jurassic to Early Cretaceous Purcell Anticlinorium in British Columbia and the Blue Ridge anticlinorium of northern Virginia and Maryland in the Appalachians, or the Nittany Valley in central Pennsylvania. Anticlines are usually developed above thrust faults, so any small compression and motion within

180-747: Is not at high altitude, the significant heights being spurs of the Serantes (Serandi): The Mallet (245m) and the Fortified Heights (123 and 106m). Its relief is contained within the north flank of the anticline of Biscay. It is a structural type relief composed of urgonian limestone from the Cretaceous period found all throughout Punta Lucero-Serantes, smoothly inclined towards the Estuary of Bilbao . The climate in Santurtzi pertains to

210-606: Is the El Dorado anticline in Kansas. The anticline was first tapped into for its petroleum in 1918. Soon after the site became a very prosperous area for entrepreneurs following World War I and the rapid popularization of motor vehicles . By 1995 the El Dorado oil fields had produced 300 million barrels of oil. The central Kansas uplift is an antiform composed of several small anticlines that have collectively produced more than 2.5 million barrels of oil. Another notable anticline

240-548: Is the Tierra Amarilla anticline in San Ysidro, New Mexico. This is a popular hiking and biking site because of the great biodiversity, geologic beauty and paleontological resources. This plunging anticline is made up of Petrified Forest mudstones and sandstone and its caprock is made of Pleistocene and Holocene travertine. The anticline contains springs that deposit carbon dioxide travertine that help to contribute to

270-765: Is trapped and stored in reservoir rock such as sandstone or porous limestone. The oil becomes trapped along with water and natural gas by a caprock that is made up of impermeable barrier such as an impermeable stratum or fault zone. Examples of low-permeability seals that contain the hydrocarbons, oil and gas, in the ground include shale , limestone , sandstone , and rock salt. The actual type of stratum does not matter as long as it has low permeability. Water, minerals and specific rock strata such as limestone found inside anticlines are also extracted and commercialized. Lastly, ancient fossils are often found in anticlines and are used for paleontological research or harvested into products to be sold. Ghawar Anticline, Saudi Arabia,

300-448: Is vertical and the angles on each side of the fold are equivalent, then the anticline is symmetrical. If the axial plane is tilted or offset, then the anticline is asymmetrical. An anticline that is cylindrical has a well-defined axial surface, whereas non-cylindrical anticlines are too complex to have a single axial plane. An overturned anticline is an asymmetrical anticline with a limb that has been tilted beyond perpendicular , so that

330-463: The structural trap for the largest conventional oil field in the world. The Weald–Artois Anticline is a major anticline which outcrops in southeast England and northern France. It was formed from the late Oligocene to middle Miocene , during the Alpine orogeny . Anticlines can have a major effect on the local geomorphology and economy of the regions in which they occur. One example of this

360-474: The beds in that limb have basically flipped over and may dip in the same direction on both sides of the axial plane. If the angle between the limbs is large (70–120 degrees), then the fold is an "open" fold , but if the angle between the limbs is small (30 degrees or less), then the fold is a "tight" fold . If an anticline plunges (i.e., the anticline crest is inclined to the Earth's surface), it will form V s on

390-517: The celebrations of the Virgin of the Carmen are carried out each year. Anticline In structural geology , an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core, whereas a syncline is the inverse of an anticline. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are

420-468: The center is called a breached or scalped anticline . Breached anticlines can become incised by stream erosion, forming an anticlinal valley. A structure that plunges in all directions to form a circular or elongate structure is a dome . Domes may be created via diapirism from underlying magmatic intrusions or upwardly mobile, mechanically ductile material such as rock salt ( salt dome ) and shale (shale diapir) that cause deformations and uplift in

450-615: The city of San Juan , Puerto Rico derives its name from Santurtzi. According to legends, the current church of St. George was originally founded as a monastery by English monks fleeing from religious persecution. They established themselves on the Basque coast, specifically the Somorrostro Valley, from which would later develop the town of Santurtzi. The name Santurtzi is derived from the Latin Sant Georgi , as

480-399: The different types of rock within each layer. During the formation of flexural-slip folds, the different rock layers form parallel-slip folds to accommodate for buckling . A good way to visualize how the multiple layers are manipulated, is to bend a deck of cards and to imagine each card as a layer of rock stratum. The amount of slip on each side of the anticline increases from the hinge to

510-403: The fault. This can result in an asymmetrical or overturned fold. An antiform can be used to describe any fold that is convex up. It is the relative ages of the rock strata that distinguish anticlines from antiforms. The hinge of an anticline refers to the location where the curvature is greatest, also called the crest . The hinge is also the highest point on a stratum along the top of

540-406: The fold. The culmination also refers to the highest point along any geologic structure. The limbs are the sides of the fold that display less curvature. The inflection point is the area on the limbs where the curvature changes direction. The axial surface is an imaginary plane connecting the hinge of each layer of rock stratum through the cross section of an anticline. If the axial surface

570-461: The humid oceanic climate type. The temperatures are moderate throughout the year, with more frequent rains in spring and autumn. Winters are mild and summers not excessively warm. The average temperature is 20 °C (70ªF) in summer and 8 °C (48ªF) in winter. Santurtzi City Council (2023-2027): Mayor Councillors The life in the area is focused on the sea, which inspires its work and its leisure. Fishing boat and rowing boat races, and

600-400: The inflection point. Passive-flow folds form when the rock is so soft that it behaves like weak plastic and slowly flows. In this process different parts of the rock body move at different rates causing shear stress to gradually shift from layer to layer. There is no mechanical contrast between layers in this type of fold. Passive-flow folds are extremely dependent on the rock composition of

630-428: The inner crust can have large effects on the upper rock stratum. Stresses developed during mountain building or during other tectonic processes can similarly warp or bend bedding and foliation (or other planar features). The more the underlying fault is tectonically uplifted, the more the strata will be deformed and must adapt to new shapes. The shape formed will also be very dependent on the properties and cohesion of

660-486: The municipality has also seen various changes. During the 19th century it was officially considered to be Santurce, however in 1901 it was divided in two. The inland part of this division would become Santurce Ortuella, as the mining town of Ortuella had grown enough to promote itself as the largest urban conglomeration of Santurce. The coastal side maintained its population base in Santurtzi, and began to be called Old Santurce. The cultural and traditional relationship between

690-628: The rich diversity of microorganisms. This area also contains remains of fossils and ancient plants from the Jurassic period that are sometimes exposed through geological erosion. The Ventura Anticline is a geologic structure that is part of the Ventura oil fields , the seventh largest oil field in California that was discovered in the 1860s. The anticline runs east to west for 16 miles, dipping steeply 30–60 degrees at both ends. Ventura County has

750-403: The sides of the fold that dip away from the hinge. Anticlines can be recognized and differentiated from antiforms by a sequence of rock layers that become progressively older toward the center of the fold. Therefore, if age relationships between various rock strata are unknown, the term antiform should be used. The progressing age of the rock strata towards the core and uplifted center, are

780-408: The stratum and can typically occur in areas with high temperatures. Anticlines, structural domes, fault zones and stratigraphic traps are very favorable locations for oil and natural gas drilling. About 80 percent of the world's petroleum has been found in anticlinal traps. The low density of petroleum causes oil to buoyantly migrate out of its source rock and upward toward the surface until it

810-509: The surface rock. The Richat Structure of the Sahara is considered a dome that has been laid bare by erosion. An anticline which plunges at both ends is termed a doubly plunging anticline , and may be formed from multiple deformations, or superposition of two sets of folds. It may also be related to the geometry of the underlying detachment fault and the varying amount of displacement along the surface of that detachment fault. An anticlinorium

840-472: The trademark indications for evidence of anticlines on a geologic map . These formations occur because anticlinal ridges typically develop above thrust faults during crustal deformations. The uplifted core of the fold causes compression of strata that preferentially erodes to a deeper stratigraphic level relative to the topographically lower flanks. Motion along the fault including both shortening and extension of tectonic plates, usually also deforms strata near

870-505: The two divisions can still be observed in the border area of Kabiezes . On 14 November 1980, Vicente Zorita Alonso —a candidate for the Basque Parliament and a long time administrative employee—was murdered by ETA as a statement against political supporters of the oligarchy . In general, Santurtzi has a very rough orography , although excluding Mount Serantes (452m) - one of its most symbolic topographic elements - it

900-795: Was the hermitage in Gordejuela near current Oquendo. In neighbouring Cantabria , Burgos and Araba exist several towns with variations of the same name: Santurde, Santiurde de Reinosa and Santurdejo. The Spanish language form Santurce first appeared in 1333, whilst its Basque counterpart would first be shown written in 1372. During the Middle Ages it could also be found referred to as San Jurdic, San Yurdie, Sturse and Santursi, amongst others. In current day, both names are used interchangeably, with certain preference given to Santurtzi , given its frequent use in Spanish. The official name of
