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 i...

description 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 its correlation with the Sangamon (Eemian) Interglacial. An "excursion', or "transition interval' of the earth's magnetic field recorded in the younger estuarine deposits, previously dated between 35 400 NP and 26 600 BP (14C ages), could indicate the Lake Mungo Event. On the other hand, littoral deposits from 38°S, dated in 30 500 BP, also recorded an "excursion' that could coincide with the Lake Mungo Event. -from Author
