The Cerro Colorado Formation is a geological formation to the south of General Carrera Lake in Patagonia. Sedimentary rocks of the Cerro Colorado Formation deposited under shallow marine conditions. [1]
Cerro Escorial is a stratovolcano at the border of Argentina and Chile. It is part of the Corrida de Cori volcanic group and its youngest member. A well-preserved 1-kilometre-wide (0.6 mi) crater forms its summit area. Lava flows are found on the Chilean and smaller ones on the Argentinian side, the former reaching as far as 3–4 kilometres (1.9–2.5 mi) from the volcano. One of these is dated 342,000 years ago by argon-argon dating.
Cerro Azul, sometimes referred to as Quizapu, is an active stratovolcano in the Maule Region of central Chile, immediately south of Descabezado Grande. Part of the South Volcanic Zone of the Andes, its summit is 3,788 meters (12,428 ft) above sea level, and is capped by a summit crater that is 500 meters (1,600 ft) wide and opens to the north. Beneath the summit, the volcano features numerous scoria cones and flank vents.
San Martín de los Andes is a city in the south-west of the province of Neuquén, Argentina, serving as the administration centre of the Lácar Department. Lying at the foot of the Andes, on the Lácar lake, it is considered one of the main tourism destinations in the province. The National Route 40 runs to the city, connecting it with important touristic points in the south of the province, such as Lanín and Nahuel Huapí national parks.
Cerro Toro is a Cretaceous landform of the Magallanes Foreland in the Patagonian region of southeastern Chile. The Cerro Toro is an element of the southern Andes and a product of the Andean orogeny, caused by the subduction of the Nazca Plate beneath the South American Plate. The formation of the Cerro Toro began in the Jurassic. The Cueva del Milodón Natural Monument is situated on the southern flank of Cerro Benítez, a lower hill associated with the formation of Cerro Toro.
The Magallanes Basin or Austral Basin is a major sedimentary basin in southern Patagonia. The basin covers a surface of about 170,000 to 200,000 square kilometres and has a NNW-SSE oriented shape. The basin is bounded to the west by the Andes mountains and is separated from the Malvinas Basin to the east by the Río Chico-Dungeness High. The basin evolved from being an extensional back-arc basin in the Mesozoic to being a compressional foreland basin in the Cenozoic. Rocks within the basin are Jurassic in age and include the Cerro Toro Formation. Three ages of the SALMA classification are defined in the basin; the Early Miocene Santacrucian from the Santa Cruz Formation and Friasian from the Río Frías Formation and the Pleistocene Ensenadan from the La Ensenada Formation.
The Casamayoran age is a period of geologic time within the Early Eocene epoch of the Paleogene, used more specifically within the South American land mammal age (SALMA) classification. It follows the Itaboraian and precedes the Mustersan age.
The Colhuehuapian age is a period of geologic time within the Early Miocene epoch of the Neogene, used more specifically within the SALMA classification in South America. It follows the Deseadan and precedes the Santacrucian age.
The Chasicoan age is a period of geologic time from 10–9 Ma within the Late Miocene epoch of the Neogene, used more specifically within the SALMA classification in South America. It follows the Mayoan and precedes the Huayquerian age.
Calabozos is a Holocene caldera in central Chile's Maule Region. Part of the Chilean Andes' volcanic segment, it is considered a member of the Southern Volcanic Zone (SVZ), one of the three distinct volcanic belts of South America. This most active section of the Andes runs along central Chile's western edge, and includes more than 70 of Chile's stratovolcanoes and volcanic fields. Calabozos lies in an extremely remote area of poorly glaciated mountains.
Cerro Colorado is Spanish for red mountain/hill. It may refer to:
A pinnacle, tower, spire, needle or natural tower in geology is an individual column of rock, isolated from other rocks or groups of rocks, in the shape of a vertical shaft or spire.
Cerro Ballena is a Chilean Late Miocene palaeontological site hosting remains of cetaceans. It is located in the Atacama Desert along the Pan-American Highway a few kilometers north of the port of Caldera. Besides cetaceans Cerro Ballena does also contains fossils of pinnipeds, sailfishes, aquatic sloths and marine invertebrate as well as trace fossils. It has about 40 cetacean individuals all of them in relatively good state. The cetaceans appear to have died at different times but due to the same causes: poisoning by toxins secreted by algae. The site was discovered in 2011 and is protected by law since 2012. It hosts an investigation centre.
The Pisco Formation is a geologic formation located in Peru, on the southern coastal desert of Ica and Arequipa. The approximately 640 metres (2,100 ft) thick formation was deposited in the Pisco Basin, spanning an age from the Middle Miocene up to the Early Pleistocene, roughly from 15 to 2 Ma. The tuffaceous sandstones, diatomaceous siltstones, conglomerates and dolomites were deposited in a lagoonal to near-shore environment, in bays similar to other Pacific South American formations as the Bahía Inglesa and Coquimbo Formations of Chile.
Cura-Mallín Group is a heterogeneous group of volcano-sedimentary formations of Oligocene-Miocene age, Colhuehuapian to Laventan in the SALMA classification, in south-central Chile and nearby parts of Argentina. The sediments belonging to the group were deposited in a lacustrine environment and alongside rivers in an intra-arc basin. Southeast of Laguna del Laja Cura-Mallín Group has a thickness of more than 1,800 metres (5,900 ft). The sediments making up the group deposited in an interval between 22 and 8 million years ago.
Caleta Herradura Formation is a geologic formation of Late Miocene (Montehermosan) age, cropping out on the Mejillones Peninsula in northern Chile. The erosion at the Coastal Cliff of northern Chile have created particularly good exposures of Caleta Herradura Formation. The formation deposited in a half graben within Mejillones Peninsula. The formation rests nonconformably on the Jorgino Formation.
Sairecabur is a volcano located on the frontier between Bolivia and Chile. It is part of the Andean Central Volcanic Zone. Sairecabur proper is 5,971 m (19,590 ft) high; other mountains in the range are 5,722 m (18,773 ft) high Curiquinca, 5,819 m (19,091 ft) high Escalante and 5,748 m (18,858 ft) high Cerro Colorado, all of which have erupted a number of lava flows. Also in close proximity to Sairecabur lie the volcanic centres Licancabur, Putana and Juriques.
Los Colorados is the name of a caldera in Chile. It is part of the Central Volcanic Zone of the Andes.
Colorado or Colorados Formation may refer to:
Hegetotherium is an extinct genus of mammals from the Early to Middle Miocene of South America. Fossils of this genus have been found in the Cerro Bandera, Cerro Boleadoras, Chichinales, Collón Curá, Santa Cruz and Sarmiento Formations of Argentina, the Nazareno Formation of Bolivia, and the Galera and Río Frías Formations of Chile.
The Colorado Basin is a sedimentary basin located in northeastern Patagonia. The basin stretches across an area of approximately 180,000 square kilometres (69,000 sq mi), of which 37,000 square kilometres (14,000 sq mi) onshore in the southern Buenos Aires Province and the easternmost Río Negro Province extending offshore in the South Atlantic Ocean.
