Contrasting copper and chromium metallogenic evolution of terranes in the Palaeoproterozoic Itabuna-Salvador-Curaca orogen, Sao Francisco craton, Brazil: new zircon (SHRIMP) and Sm-Nd (model) ages and their significance for orogen-parallel escape tectonics

Contrasting copper and chromium metallogenic evolution of terranes in the Palaeoproterozoic Itabuna-Salvador-Curaca orogen, Sao Francisco craton, Brazil: new zircon (SHRIMP) and Sm-Nd (model) ages and their significance for orogen-parallel escape tectonics

The northern segment of the Palaeoproterozoic Itabuna-Salvador-Cura collisional orogen in the Sao Francisco craton (Brazil) comprises two high-grade terranes separated by the 150 km long, N-S-trending Itiba Syenite. The Cura terrane to the west contains copper sulphide deposits hosted by hyperstheni...
