Micropaleontology Data for Larsen Basin and Patagonia from the Instituto Antartico Argentino

A bioestratigraphical zonation about Campanian-Maestrichtian and Paleocene of Larsen Basin is in progress coordinated with foraminiferal biostratigraphy. Using calcareous nannofossils, forams and diatoms, it is elaborating an evolutionary scheme describing paleoceanographic conditions during the Upper Cretaceous in the Larsen Basin.

A particular investigation is carried out about the K/T boundary with special interest in glaucony, condensed sequences, and biostratigraphical events around the boundary. Lately, all the investigations about the K/T boundary of Patagonia and Antarctica were conducted in the ETH-Zentrum (Switzerland), and University of Salamanca (Spain).
