Resumen:
Metasomatic reaction zones related to chemical interactions at peridotite- schist contacts are documented in ultramafic (UM) bodies cropping out in Rio de Las Tunas Mafic-Ultramafic Belt, Central Andes, Mendoza Province, Argentina. These UM bodies belong to an alpine type belt which has been interpreted as a dismembered and metamorphosed ophiolitic section. The mafic unit dated by Sm-Nd gave a neoproterozoic age of 655±76 Ma.
