Precambrian iron information;
Mn formation;
Sn-Ta-Nb-Li-Be pegmatites;
Imperial topaz and diaspore deposits.

RESEARCH PROJECTS

ü My research focuses the metamorphism of the Proterozoic Itabira iron formation and the Mn formation of the Barbacena Greenstone Belt in terms of mineral equilibria and fluid composition. Genetic study of the imperial topaz and diaspore deposits of the Ouro Preto district and the Sn-Ta-Nb-Li-Be pegmatites of the São João del Rey province are also of interest.
