Description

The results of geochemical, petrographic and metallographic studies in granitoid plutons from Coronel Murta-Virgem da Lapa region, Minas Gerais State, Brazil, are presented and discussed. The investigations were done using spectra of rare earth elements by plasma spectrometry. Four varieties of granites were analysed: biotite, muscovite, albite-tourmaline and pegmatoide. (M.C.K.)
