Abstract

Characterization of the lithostratigraphy, hydrothermal alteration and mineralization in the Cascavel and Sertao deposits provide the first systematic description of gold mineralization in the Faina greenstone belt. The tectono-magmatic framework of this belt is predicted by a regional-scale investigation and results of combined whole-rock g'eochemistry, in-situ zircon U-Pb, Lu-Hf and 0 isotopic measurements of regional intrusive rocks spanning > 2000 Ma constrain the crust-mantle evolution of the southern Goias Archean Block, central Brazil. Coherent geochemical and isotopic constraints imply crustal reservoirs remained fairly constant through time and suggest continental growth by in-situ additions as opposed to accretion of allochthonous terranes.
