Resumen:
Abstract.— “PRELIMINARY MINERALOGIC STUDY OF HYDROTHERMAL ALTERATION OF WALL ROCK OF THE VETA ESPERANZA SUDESTE, CATAMARCA PROVINCE, ARGENTINA”. The Agua de Dionisio district is located in Belen department, Catamarca province. The stratigraphic secuence is conformed by low grade metamorphic rocks, continental clastic sedimentites, Farallón Negro volcanic complex, sandstones and tuffites. In the district there are disseminated and veins mineralization genetically linked with the miocene magmatism. Alto la Blenda includes veins with gold and silver mineralization. The present contribution deals about preliminary study of the characteristics (type, style and intensity) of hydrothermal alteration of the wall rock of Veta Esperanza Sudeste. In this sector the monzonite have pervasive sericitic and argillic alterations. The breccia have silicic and argillic alteration.
