The Magmatic Rocks Probably Corresponding to the Andean Batholith and the Associated Metamorphic Contact Phenomena

Abstract

The knowledge about the presence of outcropping plutonic rocks in the Argentine side of the Fuegian Andes is limited exclusively to the references about the dioritic bodies, in a wider sense, of Mount Jeu Jepén (immediately to the ESE of Lake Fagnano), Spion Kop (in the Lucas Bridges Range, on Paso Harberton) hills and Estancia Túnel, to the E of Ushuaia (this intrusive was attributed to the Andean Batholith and it would be comparable or not with those of the Santa Rosa Plutonic Complex).
