The North Patagonian Batholith (Spanish: Batolito Nor-Patagónico) is a series of igneous plutons in the Patagonian Andes. The Northern Patagonian Batholith is made up of a series of plutons of granodioritic, tonalitic and dioritic composition located in the southern Andes. The plutons of the North Patagonian Batholith are of Cretaceous to Miocene age (135 Ma to 25-15 Ma). Late Miocene to early Pliocene (10 t0 5 Ma) leucogranites were also intruded. The Tertiary intrusions are centered on the strike-slip Liquine-Ofqui fault zone and include some gabbro bodies.[1]
