Study pf apatite accurrence from Gaviao and Serra de Jacabina gold deposit by scintillometry and gamma spectrometry
Description
This work presents the results of radiogeologic reconnaissance in the Cenozoic, Mesozoic and Pre-Cambrian formations, localized between Salvador and Miguel Calmon, and of the radiogeologic detail study from areas of the radioactive anomalies: Gaviao in the Riacho do Lacuipe and Canavieira Mine, in the Jacobina, Bahia States Scintilometry and gamma spectrometry results make possible to conclude by the association, in the Gaviao's apatite mineralization with throrium and the gold of the Serra de Corrego's conglamerate with uranium, make possible in the both case, orient the Search and the mining by scintilometry. The petrographic study and the radiactivity elements dispersion, suggest a sedimentary primary origin to the regional metamorphic rocks. In the Canavieiras mine was evident the stratigraphic control of the gold, associated to uranium and pirite in the conglomerates. (C.D.G.)
Abstract (Portuguese)
Este trabalho apresenta resultados do reconhecimento radiogeologico em terrenos de cenozoico e pre-cammbiano, compreendidos entre Salvador e Miguel Calmon, e dos trabalhos de detalhamento radiogeologico em duas areas de anomalias radioativa: Gaviao, no municipio de Riachao do Sacuipe, e mina de Canavieiras, no muniapio de Jacobina, Ba. Os resultados da cintilometria e espectrometria gama possibilitaram concluir pela associacao na mineralizacao da apatita de Gaviao com torio e do ouro dos conglemerados da Serra do Corrego com o uranio, possibilitando em ambos os casos orientar sua prospeccao e lavlavra pela cinitlometria. Comprovou-se o controle Citologico da jazida da apatita por piroxenios cortados por diques de pegmatitos sieniticos. Os estudos petrogaficos e a dispersao dos elementos radiotivos, sugerem origem primaria sedimentar para as rochas metamorficas regionais. Na ruina canavieras ficou evidenciado o controle estratigrafico do ouro associado ao uranio e pirita, nos conglomerados. (author)Files
