Geology and geophysics of the Sierra Verdun-Cerro Piedra del Supamo area, Estado Bolivar, Venezuela

Abstract:

The Sierra Verdun-Cerro Piedra del Supamo area is in an Early Proterozoic greenstone-granite terrane in the Guayana Shield of southeastern Estado Bolivar. Rocks of the greenstone belts are strongly foliated and are metamorphosed to the greenschist facies. A mafic-ultramafic complex was emplaced in older greenstone-belt rocks of basaltic andesite to basalt probably near the end of deformation of the greenstone belts. Historical and active placer and alluvial gold mining has stimulated recent interest in the area, which also has potential for deposits of shear-zone-hosted gold, intrusion-related gold and precious-metals, chromite, placer and lode platinum-group elements, nickel-copper ore, and lateritic nickel. -from Authors
