Mineral chemistry (major and trace elements) from ultramafic and mafic cumulates, Famatinian arc, Argentina

The dataset includes major and trace element compositions of rock-forming minerals from ultramafic and mafic cumulates of the Famatinian arc in Argentina. The purpose of these data was to investigate the petrological evolution of lower-crustal ultramafic-mafic sequences, aiming to understand the mechanism driving early magmatic differentiation in arc settings.
