Late Pleistocene Littoral Deposits from 33° to 40° S, Argentine Republic: Blake and Probable Lake Mungo Events-Magnetostratigraphic Geochronology
Geochronological data are presented on a basis of magnetostratigraphic evidence from old lagoonal deposits and younger estuarine deposits from Irazusta Quarry (33° S and 58° W). The Virtual Geomagnetic Pole Position (VGP) recorded in the lagoonal deposits, corresponds to the Blake Event and confirms...
