Resumen:
Permian?Early Triassic granitoids cropping out between Yaminué and Nahuel Niyeu villages, northeastern North Patagonian Massif can be separated into two groups: the oldest at 280 Ma, the Early Permian Granitoids (EPG) and the youngest the Late Permian- Early Triassic Granitoids (LPETG) made up by several igneous complexes that cover the time span from 255 to 245 Ma. The EPG, restricted to the east of the area, are mostly undeformed and intrude a low grade basement
