Palaeoenvironmental study of benthic foraminifera from the late Pleistocene Puente de Pascua Formation type locality, Buenos Aires province, Argentina

This paper examines the palaeoenvironmental conditions of a Late Pleistocene marine unit assigned to the Puente de Pascua Formation (MIS 5e), Buenos Aires, Argentina. For this study, a micropalaeontological (Phylum Foraminifera) and lithological analysis was conducted, based on a PPas-section extrac...

For this study, a micropalaeontological (Phylum Foraminifera) and lithological analysis was conducted, based on a PPas-section extracted in the Puente de Pascua site, located 32 km inland from the coastline of Bahía Samborombón (35°55′37” S; 57°43 ′7.6” W).

From this integrated study, palaeoenvironmental changes were established in Puente de Pascua Fm. (>66.5 kyrs).
