INSIGHTS ON THE PRE-CARBONIFEROUS TECTONIC EVOLUTION OF THE SAN RAFAEL BLOCK, MENDOZA, ARGENTINA.

The San Rafael Block (SRB) lies in the south-central part of Mendoza province, Argentina (35°S-68°30?W), and displays a NNW structural Cenozoic trend in the pre-Andean region. Geological and paleontological evidence suggest that the SRB is an extension of the Cuyania terrane. Diverse igneous-metamorphic and sedimentary events known as ?pre-Carboniferous units? (Dessanti, 1956) crop out at the SRB. New insights (stratigraphy, petrography, geochemistry and isotopic data) allow constraining the evolution of the pre-Carboniferous history of the SRB
