Abstract:
In Curimatau Microrregion, Paraiba State, Brazil, the Borborema Pegmatite Province is characterized by the presence of intrusive pegmatites dikes and sills in meta-sedimentary sequences of Serida Group. These igneous bodies are presented concentrically zoned, with a core of quartz, feldspar developing bands ranging from albite to sanidine, pure or intergrowth with quartz, disseminated or concentrated muscovite, decreasing grain size towards the contact with the host rock. The crystallization of beryl, aquamarine, tourmaline and tantalite complete the petrographic framework of pegmatite bodies. The economic importance of mineralogical group has attracted the attention of researchers since the early twentieth century, including the United States Geological Survey, which explored tantalite in this region aiming to supply raw material for making weapons of war during World War II. At the time, the miners with the unplanned practice extractive which endures to present days. Recently, strengthening cooperatives in the mineral region have brought significant improvements on mining, causing a systematic organization of its members, regulating areas with the DNPM, acquiring safety equipment and instrumentation for the various stages of mining and mineral processing, such as panning, milling, and gravimetric concentration. This set of actions has led to significant improvements in economic conditions, environmental and social sustainability in mining.
