Os fluídos associados às mineralizações de Cu dos Mociços e Ferrarias. Resultados Preliminares.

Abstract

Abstract: This work is part of the project ZOM3D – Metallogenic models of the Ossa-Morena Zone: Valorization of the mineral resources of Alentejo. This project aims for the 3D modelling of selected ore deposits, using a diversity of geoscience methods of study. The collection of mineralogical, geochemical and thermodynamic data is of major importance for the understanding of the fluid circulation dynamic responsible for the mineral concentrations in the Ossa-Morena Zone (OMZ). Petrographic and microthermometric studies of quartz fluid inclusions were carried for the Cu mineral occurrences of Mociços (zoned comb quartz and Ferrarias (comb quartz). This preliminary study presents the first data of the temperature and composition of the fluids interacting with the mineralization of the OMZ.
