1. The Juiz de Fora Complex in the region of Três Rios (RJ): lithogeochemistry, geochronology e isotopic geochemistry of Nd / O complexo Juiz de Fora na região de Três Rios (RJ): litogeoquímica, geocronologia U-Pb (LA-ICPMS) e geoquímica isotópica de Nd
The Juiz de Fora Complex (JFC) in the region of Três Rios (Rio de Janeiro) is appointed by an ample variety composicional, having from granites, tonalite to rocks of composition basic. Through the lithogeochemistry it was possible to subdivide this unity in 4 associations: (i) calc-alkaline of high-K, (ii) calc-alkaline of medium-K, (iii) tholeiitic and (iv
