Las Picazas mine is an ore vein deposit located in the San Rafael Massiff, province of Mendoza, Argentina. It is hosted by ordovician-silurian schists and genetically linked to the gondwanic magmatism. The deposit consists of four veins with an ore paragenetic sequence of arsenopyrite - sphalerite/chalcopirite - galena - pyrite - covellite in a quartz gangue with typical epithermal textures. Strain fabric of the mineralized structures suggest that they are genetically linked to the Upper Choiyoi volcanic episode (Late Permian)
