Sparry dolom ite veins and breccia bodies have a constant NS direction, and are either perpendicular to bedding with dips ~70° to the east, or parallel to bedding, dipping ~25-30° westerly. Zebra structures dis- play identical concordant and discordant relationships relative to bedding. The preferential orientation of the gangue structures is interpreted within a dextral shear zone model, where they are either controlled by tensile fractures formed during thrusting or by pre-existent anis otropies, such as bedding plan es. It is concluded that the San Vicente deposit is coeval with the host thrust zone, and therefore Late Andean in age Dewey 550 42 Département des sciences de la Terre 154 false 692 Mineral Resources and Geofluids Mineral deposits at the beginning of the 21st century A.
