Cerrejón
Cerrejón is a large 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 halted, 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.

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 and 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 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. On average the coal beds are thick, and range from to in thickness. The t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cesar-Ranchería Basin
The Cesar-Ranchería Basin ( es, Cuenca Cesar-Ranchería) is a sedimentary basin in northeastern Colombia. It is located in the southern part of the department of La Guajira and northeastern portion of Cesar. The basin is bound by the Oca Fault in the northeast and the Bucaramanga-Santa Marta Fault in the west. The mountain ranges Sierra Nevada de Santa Marta and the Serranía del Perijá enclose the narrow triangular intermontane basin, that covers an area of . The Cesar and Ranchería Rivers flow through the basin, bearing their names. The basin is of importance for hosting the worldwide tenth biggest and largest coal mine of Latin America, Cerrejón. The coals are mined from the Paleocene Cerrejón Formation, that also has provided several important paleontological finds, among others '' Titanoboa cerrejonensis'', with an estimated length of and a weight of , the biggest snake discovered to date, the giant crocodylians '' Cerrejonisuchus improcerus'', '' Anthracosuchus bal ...

Titanoboa
''Titanoboa'' (; ) is an extinct genus of very large snakes that lived in what is now La Guajira in northeastern Colombia. They could grow up to , perhaps even long and reach a body mass of . This snake lived during the Middle to Late Paleocene epoch, around 60 to 58 million years ago, following the extinction of all non-avian dinosaurs. Although originally thought to be an apex predator, the discovery of skull bones revealed that it was more than likely specialized in preying on fish. The only known species is ''Titanoboa cerrejonensis'', the largest snake ever discovered, which supplanted the previous record holder, '' Gigantophis garstini''.''Titanoboa cerrejonensis'' at |
Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.

Coal Mining
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to th ...

Ranchería River
The Ranchería River ( es, Río Ranchería) is a river located in northern La Guajira Department, Colombia. Born in the Sierra Nevada de Santa Marta southern steps flows south, abruptly turns northeast and then north where it finally flows into the Caribbean Sea. It is the main river of La Guajira Department and has great significance for the Wayuu people. A large dam, the "El Cercado", was first proposed in the 1950s in the Sierra Nevada de Santa Marta mountains, as an irrigation source for agribusiness and for the population of at least nine municipalities. The Sierra Nevada Indigenous communities protested the dam, which they regarded as a systematic appropriation of the river by landowners and the coal mining industry (the world's largest open-pit coalmine, Cerrejón, is allowed around 16% of the river's volumetric flow). It was completed in the mid 2000s (picture) The river flows down to a region of water scarcity in the semi-desert lowlands to the north and west. Four water ...
