North Patagonian Batholith centered on the strike-slip Liquine-Ofqui fault zone and include some gabbro bodies. North Patagonian Batholith The North Patagonian Batholith () is a series of igneous plutons in the Patagonian Andes of Argentina and Chile. The Northern Patagonian Batholith was formed in the Mesozoic Era and Cenozoic Era. It is made up of a collection of individual plutons made up of granodiorite, tonalite and diorite among other rocks. Most plutons of the North Patagonian Batholith are of Cretaceous Period to the Miocene age of the Neogene Period (135 Ma to 25-15 Ma), during the Mesozoic Era. Late Miocene to early Pliocene
Patagonian Desert the desert and is why, despite approximately half of the desert being only about 200 miles from the ocean, such a large desert is found in the region. The cold Falkland Current off the Atlantic coast of South America also contributes to the area's aridity. Different climates can be distinguished: the coast north of the 45th parallel is much milder because of the warm currents from Brazil, and the entire northern half of the region is significantly warmer in the summer, when sunny weather predominates. Daily temperatures in the summer reach 31 °C in the Rio Colorado region, a general
