Resumen:
In central Comechingones pegmatitic field (CPF), Sierras Pampeanas de Córdoba, Be-Nb-Ta granitic pegmatites from the Cerro Redondo group were emplaced during the famatinian Guacha Corral shear zone (GCSZ) deformation. Host lithologies include Bt-Grt gneisses, stromatic and nebulitic migmatites, and minor amphibolites generated during pampean orogeny. These protholiths were variably deformed during famatinian orogeny, leading to mylonitic fabrics development. Detail geological-structural mapping and microstructures analyses suggest a synkinematic emplacement of these pegmatites with ductile deformation of the GCSZ. These evidences complement the emplacement model previously developed for other pegmatitic groups of CPF.
