Abstract

During minerals research performed in Rio de Janeiro state, in the counties of Parati, Rio Claro and Piraí in the early 80 detected the presence of scheelite in concentrate panning from drains of Monumento/Cacaria area. Until this study, the lithology source responsible for this occurrence was unknown. In order to define the source and characterize the genesis of the tungsten mineralization, there were panned-concentrate drainage sampling in streams of  the area, geological mapping in detailed scale (1:25.000) and collect of rock samples for characterization in analytic methods. The study area is located in the evolution context of Ribeira Belt, characterized by precambrian gneisses and the mineralization  was classified as a stratabound scheelite, calcisilicate hosted.
