| dc.description | The region of São José do Rio Pardo is made up of gneisses, granulites and migmatites of Precambrian age. Two granulitic varieties are described: acid alaskit granulites and pyroxene granulites both of which together with normal gneisses form the paleosoma of migmatites. The pyroxene granulite belongs to a true charnockitic series with the chemical caracteristic of differentiated calc-alkaline rocks. Geochronological determinations indicate an age of about 600 m.y. for the migmatite formation, and somewhat older ages for granulites. Metamorphic differentiation, chiefly through anatexis, producing anhidrous (charnockitic} residual associations, seems to have been the principal factor responsible for the formation of the granulites. | en-US |
