Origin of permafrost lake deposits in the Central Andes
Perennially frozen lacustrine deposits in the Bolivian Altiplano are discussed. They are situated between 21°38′S and 23°13′S at an elevation of 4117–4730 m ASL. It is hypothesized that these ice‐rich lacustrine deposits formed as the result of subaquatic freezing of sediments in the Late Pleistocen...
