Caribe Terrane
The Caribbean Terrane ( es, Terreno del Caribe, ''TC'') is one of the geological provinces (terranes) of Colombia. The terrane, dating to the Late Cretaceous, is situated on the North Andes Plate and borders the La Guajira, Chibcha and underlying Tahamí Terrane along the regional Bucaramanga-Santa Marta Fault.Paris et al., 2000, p.10 The terrane overlies the Tahamí, Arquía and Quebradagrande Terranes along the Romeral Fault System.Paris et al., 2000, pp.20–26Gómez Tapias et al., 2015, p.209 Reinterpretation A study performed by Mora Bohórquez et al. in 2017 showed no basement variation between the Chibcha Terrane San Lucas basement underlying the Lower Magdalena Valley (VIM) and the SNSM basement to the east of the Santa Marta Fault. The authors redefined the contacts between the different terranes, using the names Calima Terrane for the coastal portion of the Caribbean Terrane ( San Jacinto and Sinú foldbelts) and Tahamí-Panzenú Terrane for the Tahamí Terran ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chocó Department
Choco Department is a department of Western Colombia known for its large Afro-Colombian population. It is in the west of the country, and is the only Colombian department to have coastlines on both the Pacific Ocean and the Atlantic Ocean. It contains all of Colombia's border with Panama. Its capital is Keebdaw. Chocó has a diverse geography, unique ecosystems and unexploited natural resources. However, its population has one of the lowest standards of living of all departments in Colombia. A major factor, cited by the government, is the rugged, montane rainforest environment, limiting any infrastructure improvements to the region. No major highway has been worked on since initial foundations were laid down in 1967. This roadway would have successfully linked Chocó to the nearest large city, Medellin, providing easier access to medical care, necessities, food, and more. Currently, depending on their location, residents of Chocó who are in a medical emergency, and who do h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Colombia
Geology of Colombia refers to the geological composition of the Republic of Colombia that determines its geography. Most of the emerged territory of Colombia covers vast areas within the South American plate, whereas much submerged territory lies within the Caribbean plate and the Nazca plate. Geologic history As in the rest of South America, a combination of external and internal tectonic, volcanic, and glacial forces over the eons formed Colombia's present-day geology.Bushnell, David and Rex A. Hudson. "Geology". I''Colombia: A Country Study''(Rex A. Hudson, ed.), pp. 70-71. Library of Congress Federal Research Division (2010). Island-like outcrops of metamorphic rocks in the eastern Llanos are visible remnants of Precambrian times. During the 289-million-year-long Paleozoic Era, which began 539 million years ago, the ocean invaded the area which is exposed in Colombia's Andean zone, as subterranean volcanic eruptions in the western part of the country spouted lava.

Terrane
In geology, a terrane (; in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or " sutured" to crust lying on another plate. The crustal block or fragment preserves its own distinctive geologic history, which is different from that of the surrounding areas—hence the term "exotic" terrane. The suture zone between a terrane and the crust it attaches to is usually identifiable as a fault. A sedimentary deposit that buries the contact of the terrane with adjacent rock is called an overlap formation. An igneous intrusion that has intruded and obscured the contact of a terrane with adjacent rock is called a stitching pluton. Older usage of ''terrane'' simply described a series of related rock formations or an area having a preponderance of a particular rock or rock groups. Overview A tectonostratigraphic terrane is not necessarily an independent microplate in origin, since it may not contain the full thickness ...

Montes De María
The Montes de María is an isolated group of small mountains near the northern coast of Colombia in the Caribbean Region. The Montes de María (also known as Serranía de San Jacinto) are the last part of the Serranía de San Jerónimo which extends from the West Andes. A part of the mountains are protected as the Los Colorados fauna and flora sanctuary. Montes de María is a zone located in the center of the Colombian Departments of Bolívar and Sucre. The following towns are part of the Montes de María: El Carmen de Bolívar, María La Baja, San Juan Nepomuceno, San Jacinto, Córdoba, Zambrano and El Guamo in Bolívar; Ovejas, Chalán, Colosó, Morroa, Toluviejo, Los Palmitos and San Onofre in Sucre. It has a total area of , of which are in Bolívar and in Sucre. This area has a population of about 330,889. Montes de María comprises two zones: The first zone called Baja Montaña is relatively flat with no mountains: the area located between the Troncal de O ...

Serranía Del Baudó
The Serranía del Baudó is a coastal mountain range on the Pacific coast of Colombia. It is separated from the West Andes by the Atrato valley where the Atrato River flows and Quibdó is located. From the south the range extends from the Baudó River north and slightly west along the coast into Panama terminating at the Golfo de San Miguel. The range is called Serranía del Sapo when it is in Panama. Technically the landform extends south of the Baudó River down to Malaga Bay, but the area has been eroded into low hills and marshlands. From Cabo Corrientes north to Punta Ardita and on into Panama the Baudó Mountains meet the ocean in steep cliffs, rising up to as high as , with small indentations in the coast providing small pocket beaches, some sandy, but most are shingle or cobble. However, near river mouths the coast has been eroded and there are wide sandy beaches, tidal flats and even mangrove swamps. The highest point, Alto de Buey, is . Geology Geologically, the S ...

Serranía Del Darién
The Serranía del Darién is a small mountain range on the border between Colombia and Panamá in the area called the Darién Gap. It is located in the southeastern part of the Darién Province of Panamá and the northwestern part of the Chocó Department of Colombia. There are two major protected areas here: Darién National Park in Panamá and Los Katíos National Park in Colombia. Serranía del Darién range's average elevation above sea level is . These mountains have sparse settlements, with just two people living in every square kilometer. This lack of human settlements is reflected in the fact that the nearest town with a population of 50,000 is over 12 hours by road. Geological hazards The Serranía del Darién is notorious for strong earthquakes; on average earthquakes measuring between 6 and 7 occur here every 50 years. The area is also susceptible to floods and landslides, both of which have been classified as medium to high intensity hazards for the region. Climate S ...
