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 Late Miocene up to the Early Pliocene, roughly from 9.6 to 4.5 Ma.
The basin has a 2-kilometre (1.25-mile) thick sedimentary fill, which is about half the thickness of more northern foreland basins in Peru. [2] The oldest known sediments are the Eocene sandstones of the Caballas Formation, while the youngest deposits, the fossiliferous Pisco Formation, date to the Early Pleistocene.
Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed. Such sites may have separate entries if they are considered to be more notable than the formation as a whole.
The Andean orogeny began in the late Triassic.In the south, the two kilometer Chocolate Formation formed with sedimentary rocks into the late Triassic. [8] Central Peru experienced less magmatic activity than during the Hercynian orogeny, but acid plutonic rocks emplaced in the center of the country.
