Embora o potencial mineral do Brasil seja imenso e, por conseguinte, a possibilidade de encontro de novas especies minerais nos empreendimentos minerarios seja naturalmente alta, ate 2010 somente 51 descobertas haviam sido verificadas no pais. Entretanto, nos ultimos sete anos, atraves de um projeto de Tese de Doutoramento realizado no Programa de Pos-Graduacao em Geologia do IGC/UFMG, esta situacao procurou ser mudada. Com enfase em dois dos principais ambientes geologicos do Estado de Minas Gerais e adjacencias, a Provincia Pegmatitica Oriental do Brasil e a Serra do Espinhaco, estudos foram conduzidos visando especificamente o encontro de novos minerais. Destacam-se os resultados extremamenete satisfatorios; nesses anos foram descobertos oito minerais, o que representa media de 1,3 mineral/ano, contrastando com os inexpressivos 0,2 mineral/ano verificados desde 1789 (ano em que o crisoberilo foi descrito). Os novos minerais sao, incluindo seus codigos de identificacao na International Mineralogical Association (IMA): carlosbarbosaita [(UO2)2Nb2O6(OH)2.2H2O], IMA 2010-047; pauloabibita [NaNbO3], IMA 2012-090; cesarferreiraita [Fe2+Fe3+2(AsO4)2(OH)2.8H2O], IMA 2012-099; correianevesita [Fe2+Mn2+2(PO4)2.3H2O], IMA 2013-007; almeidaita [Pb(Mn,Y)Zn2(Ti,Fe3+)18O36(O,OH)2], IMA 2013-020; wilancookita [(Ba,K,Na)8(Ba,Li,[])6Be24P24O96.3H2O], IMA 2015-034; parisita-(La) [CaLa2(CO3)3F2], IMA 2016-031; e brandaoita [BeAl2(PO4)2(OH)2(H2O)4], IMA 2016-071a. Este foi o primeiro programa de pesquisa desenvolvido no pais voltado especialmente para a descoberta de novos minerais, tendo alcancado pleno exito.

MANOEL TEIXEIRA DA COSTA - CPMTC, GEOSCIENCES INSTITUTE (UFMG). Although the mineral potential of Brazil is immense and, consequently, the possibility of finding new mineral species in mining projects is obviously high, until 2010 only 51 discoveries had been verified in this country. However, in the last seven years, through a PhD Thesis project carried at the Postgraduate in Geology Program of the IGC/UFMG, this situation has been modified. With emphasis on two of the main geological environments of Minas Gerais State and surrounding regions, the Eastern Brazil Pegmatite Province and the Espinhaco Mountain Range, studies were conducted specifically aimed at finding new minerals. The results are extremely satisfactory; in those years eight minerals were discovered, representing an average of 1.3 mineral/year, contrasting with the inexpressive 0.2 mineral/year verified since 1789 (year of chrysoberyl description). The new minerals are, including their identification codes in the International Mineralogical Association (IMA): carlosbarbosaite [(UO2)2Nb2O6(OH)2.2H2O], IMA 2010-047; pauloabibite [NaNbO3], IMA 2012-090; cesarferreiraita [Fe2+Fe3+2(AsO4)2(OH)2.8H2O], IMA 2012-099; correianevesite [Fe2+Mn2+2(PO4)2.3H2O], IMA 2013-007; almeidaite [Pb(Mn,Y)Zn2(Ti,Fe3+)18O36(O,OH)2], IMA 2013-020; wilancookite [(Ba,K,Na)8(Ba,Li,[])6Be24P24O96.3H2O], IMA 2015-034; parisite-(La) [CaLa2(CO3)3F2], IMA 2016-031; and brandaoite [BeAl2(PO4)2(OH)2(H2O)4], IMA 2016-071a. This was the first research program developed in the country focused especially on the discovery of new minerals, reaching full success.
