Abstract
The aim of this paper is to present a synthesis of the geologic evolution in the Belo Horizonte Sheet comprising an area about 281.210 Km{sup 2}. Rb-Sr and K-Ar isotope dating methods are used for age estimation of geologic deposits. The geologic evolution of the cratonic area is reflected by a stable central nucleus surrounded by marginal orogenic belts. In the central area were recognized greenstone belts structures involved by granite terrains and bordered by a granulitic region. The framework of the Sao Francisco Craton involves events of metamorphism, granitogenesis, sedimentary, volcanism and plutonism developed in the Early to Late Proterozoic. The stratigraphic column is complemented by Late Jurassic-Early Cretaceous continental deposits belonging to Parana-Basin. (M.V.M.).
