Geological and geochemical setting of the Mazán Granite containing andalusite-pegmatites, Argentina

Abstract

The Mazán pegmatitic fi eld integrates the Pampean Pegmatitic Province. It is located at northeastern of the La Rioja province, Northwestern Argentina. The pegmatites from Mazán fi eld have spatial relationship with Mazán Granite –MGdefi ned by Fogliata and Avila (1997). We found magmatic andalusites from pegmatites in MG, but they are not found in other pegmatites in Argentina so far. The main goal of this paper is to characterize MG and its andalusite-bearing pegmatites associated inside of geological and geochemical setting.
