1. Geologia, geometalurgia, controles e gênese dos depósitos de fósforo, terras raras e titânio do complexo carbonatítico Catalão i , GO
This work describes the geological and geometallurgical characteristics of the phosphate, titanium, niobium and rare-earth elements deposits in the northeast part of the Catalão I carbonatite complex, Central Brazil. The mineralization controls were determined for magmatic, metasomatic and weathering processes. The ore types were defined on the basis of geo

2. Estudo de mineralizações de tipo Cu-porfiro do sul do Peru por meio de sensoriamento remoto e aeromagnetometria
A large number of mineral deposits are known in the Andes, including Cu-porphyry deposits. Among these, Cuajone, Quellaveco and Toquepala are some of the most important in the southern portion of Peru. They are located in the domain ofthe Bolivian Orocline, within the Incapuquio shear zone, a structure that controls the mineralization, ofabout 60 Ma. Airborn

3. Estudos geoquimicos e isotopicos das mineralizações auriferas e rochas associadas da Região de Pontes e Lacerda (MT)
Geochemistry and isotope studies were carried out on the gold deposits of Pontes e Lacerda region (Mato Grosso state, Brazil) where rocks of the Aguapei and Rondoniense mobile belts (SW of Amazon Craton) occur. The stratigraphy of this part of Amazon Craton consists of the Pontes e Lacerda Metavulcano-sedimentar Sequence (PLMVSS), Santa Helena Granite-Gneiss
