Resumen:
The Mazán Granite (MG) is located in the homymous range of the Sierras Pampeanas, Northwesten Argentina. The metasedimentary host rocks and their enclaves present into the magma, presence of cordierite in the granite and andalusite in the associated pegmatites are valid geological features to allow inferring a supracortical placed for MG. The geochemical feature more notable for MG is the highly peraluminous character. According to the mineralogical, petrographical and geochemical characteristics, the MG could be considered a typical S-type pegmatite generating granite from Pampean Pegmatitic Province, although isotopic data is not available yet.
