Lake Minchin
Lake Minchin is a name of an ancient lake in the Altiplano of South America. It existed where today the Salar de Uyuni, Salar de Coipasa and Lake Poopó lie. It was formerly considered the highest lake in the Altiplano but research indicated that the highest shoreline belongs to the later Lake Tauca instead. The concept of a "Lake Minchin" was first coined in 1906 and the name is based on John B. Minchin. The dating of the lake varies but probably lasted until 22,000 – 21,000 BP. A glacier advance was in progress in the Andes during that time period. The name "Minchin" has also been used in other contexts, and it has been proposed that the lake was actually a combination of several different paleolakes. Definition The name "Lake Minchin" has been used inconsistently to refer to either a lake existing 45,000 years ago, the highest lake in the Altiplano, or to sediment formations. This confusion has led to calls to drop the usage of the name "Minchin". An alternative theory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saltwater Lake
A salt lake or saline lake is a landlocked body of water that has a concentration of salts (typically sodium chloride) and other dissolved minerals significantly higher than most lakes (often defined as at least three grams of salt per litre). In some cases, salt lakes have a higher concentration of salt than sea water; such lakes can also be termed hypersaline lakes, and may also be pink lakes on account of their colour. An alkalic salt lake that has a high content of carbonate is sometimes termed a soda lake. One saline lake classification differentiates between: *subsaline: 0.5–3‰ (0.05-0.3%) *hyposaline: 3–20‰ (0.3-2%) *mesosaline: 20–50‰ (2-5%) *hypersaline: greater than 50‰ (5%) Properties Salt lakes form when the water flowing into the lake, containing salt or minerals, cannot leave because the lake is endorheic (terminal). The water then evaporates, leaving behind any dissolved salts and thus increasing its salinity, making a salt lake an excellent place ...

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species. The anatomy, behavior, feeding, and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salinas De Garci Mendoza
Salinas de Garci Mendoza (formerly: Salinas de Thunupa) is a town in the Bolivian Oruro Department. It is the administrative center of Ladislao Cabrera Province and is located south-west of Oruro, the capital of the department. It is situated at an elevation of at ''Caricha'' (), 20 km north of the Tunupa stratovolcano. Salar de Coipasa,a salt lake, is 20 km north-west of Salinas de Garci Mendoza, and 15 km in south-eastern direction is Salar de Uyuni, the world's largest salt pan. Salinas de Garci Mendoza is the endpoint of the road from Chuquichamba via Andamarca and Aroma to Salinas de Garci Mendoza. Salinas de Garci Mendoza bears the title "Capital of Quinoa" because of the intensive cultivation of the quinoa Quinoa (''Chenopodium quinoa''; , from Quechua ' or ') is a flowering plant in the amaranth family. It is a herbaceous annual plant grown as a crop primarily for its edible seeds; the seeds are rich in protein, dietary fiber, B vitamins, and . ...

Salar De Ascotán
Salar de Ascotán, also known as Salar de Cebollar, is a Salt pan (geology), salt flat in northern Chile. Its drainage basin is and is shared with Bolivia. The basin is bordered on the north by the Salar de Carcote basin, on the east by small endorheic basins, including those of Laguna Cañapa and Laguna Hedionda (Nor Lipez), Laguna Hedionda, from which is separated by the crest of the Cerros de Cañapa, Cerro Araral and others. To the south, the basin is bordered by the San Pedro de Inacaliri River basin, while to the west the drainage divide between the salt flat and the Upper Loa River basin is marked by the summits of a chain of volcanoes culminating in Palpana. Salar de Ascotán has a surface area of and the train line of the FCAB runs on the west side of the salt flat for over . The salt pan was formerly filled by a large lake that was separated from Lake Minchin by a barrier at least high. References Salt flats of Chile, Ascotan Volcanoes of Antofagasta Regio ...
