Abstract

Calcretes closely linked with fossil ice-wedge pseudomorphs in Pleistocene alluvial deposits are widespread in Patagonia from Rio Negro to Rio Gallegos. As carbonate rocks are absent in the region, the questions to be asked are: where did the calcium carbonate come from, how did it accumulate, what does this relationship between calcium carbonate and cryogenic structures mean? The AA. present the first results of an attempt to understand their origin and to define the environment which controlled their development
