Cerrejón Formation
The Cerrejón Formation is a geologic formation in Colombia dating back to the Middle-Late Paleocene. It is found in the El Cerrejón sub-basin of the Cesar-Ranchería Basin of La Guajira Department, La Guajira and Cesar Department, Cesar. The formation consists of bituminous coal fields that are an important economic resource. Coal from the Cerrejón Formation is mined extensively from the Cerrejón open-pit mining, open-pit coal mine, one of the largest in the world. The formation also bears fossils that are the earliest record of Neotropical rainforests.Wing et al., 2009 Definition The formation was first named Septarias Formation and in 1958 renamed to Cerrejón Formation by Thomas van der Hammen, probably based on an earlier report by Notestein.Rodríguez & Londoño, 2002, p.163 Geology The Cerrejón Formation, with an assigned total thickness of , is subdivided into lower, middle, and upper groups based on the thickness and distribution of coal beds.

Cerrejón
Cerrejón is a large Coal mining, open-pit coal mine in Northern Colombia owned by Glencore. At Cerrejón, low-ash, low-sulphur bituminous coal from the Cerrejón Formation is excavated. At over the mine is one of the largest of its type, the largest in Latin America and the tenth biggest in the world. Cerrejón is divided into three sections, North Zone, Central Zone and South Zone. Total proven reserves are estimated at 503 megatonnes. In 2016, the mine produced . In June 2020, lawyers for the local Wayuu community lodged a request to the United Nations special rapporteur for human rights and the environment for work to be immediately halted over environmental and human rights concerns. In September 2020, several UN independent human rights experts called for the mining operations to be temporarily suspended, citing the serious damage to the environment and the negative effects on the health and other rights of the indigenous peoples who live in the area due to the spread of co ...

Neotropical
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean Islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Facies
In geology, a facies ( , ; same pronunciation and spelling in the plural) is a body of rock with distinctive characteristics. The characteristics can be any observable attribute of rocks (such as their overall appearance, composition, or condition of formation) and the changes that may occur in those attributes over a geographic area. A facies encompasses all the characteristics of a rock including its chemical, physical, and biological features that distinguish it from adjacent rock. The term "facies" was introduced by the Swiss geologist Amanz Gressly in 1838 and was part of his significant contribution to the foundations of modern stratigraphy, which replaced the earlier notions of '' Neptunism''. Walther's law Walther's law of facies, or simply Walther's law, named after the geologist Johannes Walther, states that the vertical succession of facies reflects lateral changes in environment. Conversely, it states that when a depositional environment "migrates" laterally, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Cruz Formation, Venezuela
Santa Claus (also known as Saint Nicholas, Saint Nick, Father Christmas, Kris Kringle or Santa) is a legendary figure originating in Western Christian culture who is said to bring gifts during the late evening and overnight hours on Christmas Eve. Christmas elves are said to make the gifts in Santa's workshop, while flying reindeer pull his sleigh through the air. The popular conception of Santa Claus originates from folklore traditions surrounding the 4th-century Christian bishop Saint Nicholas, the patron saint of children. Saint Nicholas became renowned for his reported generosity and secret gift-giving. The image of Santa Claus shares similarities with the English figure of Father Christmas, and they are both now popularly regarded as the same person. Santa is generally depicted as a portly, jolly, white-bearded man, often with spectacles, wearing a red coat with white fur collar and cuffs, white-fur-cuffed red trousers, a red hat trimmed with white fur, a black lea ...

Catatumbo Basin
The Catatumbo River () is a river rising in northern Colombia, flowing into Lake Maracaibo in Venezuela. The Catatumbo River is approximately long. It forms a part of the international boundary between the two countries. The river flows through the Catatumbo moist forests ecoregion. It then flows through the Maracaibo dry forests ecoregion before emptying into Lake Maracaibo. Prior to emptying into Maracaibo, the Catatumbo River also merges with the Zulia River. Together with the nearby Escalante River, Catatumbo is a producing area for cocoa beans of the Criollo cultivar. Catatumbo lightning The "Relámpago del Catatumbo" or "Faros del Catatumbo" (Catatumbo lightning) is a phenomenon that occurs over the marshlands at the Lake Maracaibo mouth of the river, where lightning storms occur for about 10 hours a night, 140 to 160 nights a year, for a total of about 1.2 million lightning discharges per year. The light from this storm activity can be seen up to away and has been u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maracaibo Basin
The Maracaibo Basin, also known as Lake Maracaibo natural region, Lake Maracaibo depression or Lake Maracaibo Lowlands, is a foreland basin and one of the eight natural regions of Venezuela, found in the northwestern corner of Venezuela in South America. Covering over 36,657 square km, it is a hydrocarbon-rich region that has produced over 30 billion bbl of oil with an estimated 44 billion bbl yet to be recovered. The basin is characterized by a large shallow tidal estuary, Lake Maracaibo, located near its center. The Maracaibo basin has a complex tectonic history that dates back to the Jurassic period with multiple evolution stages. Despite its complexity, these major tectonic stages are well preserved within its stratigraphy. This makes The Maracaibo basin one of the most valuable basins for reconstructing South America's early tectonic history. Geologic setting The Maracaibo basin is surrounded by two mountain ranges, the Méridas Andes to the southeast and the Sierra de Perij ...
