Resumen:
The Cerro Valdivia is one of the southest expressions of Sierras Pampeanas. On the north, different metamorfic rocks with mafic and ultramafic composition are related with Pie de Palo Complex (1018 My). In this study, metamorfic units with mafic and ultramafic protolites were identified. Talc schist, anfibolic schist and masive anfibolites rocks experimented low to medium grade of regional metamorfism according their mineral associations. Geochemical analysis confirms the igneous procedence with mafic and ultramafic composition, emplaced as cumulates in arc/back arc environment in mesoproterozoic times.
