Abstract

The study of new and rare mineral species from Brazil seeks to increase the current mineralogical knowledge, through researches that involve the determination of crystal structures (resolution by the direct method or refinement by the Rietveld method) and the solution of mineralogical nomenclature problems. Studies regarding the relationship among these minerals and their associations (assemblages, rocks, genesis, paragenesis) will also be developed. The complete description of new minerals from Brazil, in agreement with the rules of the Commission on New Minerals, Nomenclature and Classification (CNMNC) of the International Mineralogical Association (IMA) will be done, with submission of nomenclature proposals.For execution of this project, samples already collected in several Brazilian occurrences will be used, as well as type-specimens, some already obtained and other to be obtained by exchange with museums, and samples obtained during new field works in Brazilian occurrences. The main new minerals-bearing rocks, already partially studied in previous stages, are granitic pegmatites from several places of Minas Gerais, besides the Cajati carbonatite, in São Paulo. Researches of Scientific Initiation, Technical Training, Master's degree, Doctorship's degree and Post-Doctorship related to the subject of this project will be implemented. (AU)
