AbstractAbstract
[en] In order to detect the geochemical tendency of uranium mineralization at Campo do Agostinho of Pocos de Caldas alkaline complex 10 oxides (U3O8, ThO2, ZrO2, MoO3, As2O3, SrO, Y2O3, TiO2, CaO and K2O) were analysed by X-ray fluorescence spectroscopy. The correlation coefficients of uranium with all other elements, except potassium, were found to be high with values more than 90%. A similar situation is observed with respect to thorium with a high degree of correlation with other elements (excepting strontium), the correlation coefficients being in excess of 95%. This tendency shows that nine analysed elements participate in all phases of uranium mineralization at Campo do Agostinho. The same tendency is also observed in another locality at Campo do Cercado uranium mine within the same alkaline complex. (Author)

Analizaram-se, por meio de espectrometria de raios X fluorescente, 10 oxidos de complexos alcalinos (U3O8, ThO2, ZrO2, MoO3, As2O3, SrO, Y2O3, TiO2, CaO e K2O) nas 62 amostras coletadas, ao longo das galerias de pesquisa de uranio perfuradas no Campo do Agostinho. Os coeficientes de correlacao do uranio com todos os outros elementos, com excecao do potassio, sao altos, com valores maiores que 90%. Situacao semelhante observa-se com relacao ao torio, com alto grau de correlacao com outros elementos (excecao do estroncio) sendo os coeficientes de correlacao de 95%. Esta tendencia mostra que 9 elementos analisados participam em todas as fases de mineralizacao no Campo do Agostinho. A mesma tendencia e observada em outra localidade, na mina de uranio do Campo do Cercado, dentro do mesmo complexo alcalino. (Autor)Original Title
