Magmatic and metamorphic evolution of the Faina geenstone belt and its implication for the metallogeny of Au-Cu-Fe mineral systems.

The Goiás Massif, an Archean block located in the central portion of Brazil, presents five greenstone belts terrains that all show important mineral deposits variety, ranging from orogenic gold, intrusion related and paleo placer occurrences. The Faina Greenstone Belt (FGB), despite of your regional significance and your historical exploration, is little known in terms of the exact source of metals and of the chronological emplacement of each orogenic cycle. This project aims to develop a break-through in Precambrian metallogeny by using new approaches for understanding the deep magma content and the metal fertilization with respect to better comprehend the metallogenetic evolution of the Faina greenstone belt.

The PhD research project aims to build a time-chronological event chart of the greenstone belt and characterize the mineralizing systems comprised by the structure of it, as well as its relation with regional settings. The research focuses in a geochemical approach of intrusive rocks to fingerprint magma/ fluid sources and the metal fertility.

In order to fulfill its purpose, the main points of the research include:
-   Understand the tectonic setting of the intrusions and the mineral association related to them    (geochronological and structural data base);
-   Comprehend the dynamics of the FGB based on chronologic data obtained and your association with  the structures, ore-forming processes and alterations;
-   Evaluate the metallogenetic potential of the FGB by the interpretation and analysis of the obtained

The project is funded by a scholarship provided by the Brazilian Government program ’Science without Borders’.
