%X This work follows the studies concerning the identification of Sao Paulo Shear zone tectonic structures, based on the visual interpretation of orbital TM-LANDSAT imagey. The study area includes Natividade da Serra and Caraguatatuba sheets. The litostratigraphic units are composed of granites associated with migmatites from the upper pre-Cambrian age, sin-tardi to pos-tectonics, metasediments from lower-middle pre-Cambrin reworked in the Brasilian Tectonic Event (pre-Acungui and Acungui Group)and granulite rocks (Costeiro Complex). Structures with sinistral movement contrary to the general structure of the area (N50-60E, dextral)were identified in the granulite rocks. A more refined mapping than the one previously obtained was possible by associating photogeological studies with field work data. It was also possible to identify foliations of thrust faults in the N40-60W direction, possibly related to dextral shear zones.
