Geochemistry and Geologic Mapping

The depth of the Benioff zone has been determined from the new analysis of volcanic rocks and from new seismic data from S.W. Bolivia. Both data give consistently 260 km as a depth of the Benioff zone and for the origin of magma of calc-alkali magma series in SW-Bolivia. These inferences are consistent with the plate tectonics model.
