The Paragominas Bauxite Province is located in eastern of Pará state and western of Maranhão state, occupying the NW portion of Grajaú Basin and the southern of Bragantina platform, with an area of approximately 50.000 km2. The important bauxite deposites from that area were originated by an intense chemistry weathering above siliciclastic rocks from Cretaceous age. This research focus on the mineralogical e geochemistry studies of bauxite profiles in the area of Bauxite mine that belongs to the Norsk Hydro Company, in Miltonia 3 mine, municipality of Paragominas, Pará state. This research aims to contribute to understanding of the origin and developing of these profiles. Were conducted two sample collections of lateritic profiles represent...
