Contribution to the geology of the surrounding area of Registro, São Paulo State)

Abstract

This paper deals about an outline of the geology, tectonics and quaternary depositional environment close to rio Ribeira valley, in the southea'st part of São Paulo State, like as a result of geological mapping carried out in scale 1:50.000 and sedimentological studies. A synthesis of the following units are presented: a) migmatites, schistes and granite of the middle Pre-cambrian; b) inconsolidated sediments of the Pleistocene Pariquera-Açu Formation; c) Holocene marine sands, peats and clay. Evidences of gravitational faults, occurred in neo-cenozoic, along old directional structures, forming the coastal plain of Cananéia-Iguape are showed
