Abstract

The integration of Neogene deposits in a regional framework evidences their large areal distribution in the extra Andean foreland region of Central Argentina. Acorrelation scheme is proposed for placing the different lithostratigraphic units identified within a regional geological evolutionary model. The stratigraphic and sedimentological analyses suggest that after the marine regression of the Paranense Sea, two major cycles of continental deposition, separated by a regional unconformity, occurred in the late Miocene and the Pliocene respectively. The areal extension of the Late Miocene and the Pliocene sedimentary basins does not coincide; the Pliocene basin with more restricteda real extension, dominantly developed southward.
