The Colangüil Batholith is a group of plutons in western Argentina between the latitudes of 29 and 31° S. The plutons of the batholith were emplaced and cooled in the Late Paleozoic and the Triassic . Runs in a north–south direction. The plutons of the batholith are intruded into volcanic rocks produced by the same plutons plus some earlier deformed basement. The most common rocks in the batholith are granodiorite , granite and leucogranite . The batholith contains also a dyke swarm of north–south trending dykes. Compared to other subduction-related batholiths around the Pacific Ocean Colangüil Batholith is more felsic .
3-753: Together with the Chilean Coastal Batholith and the Elqui-Limarí Batholith the Colangüil Batholith is a remnant of the volcanic arcs that erupted the volcanic material of the Choiyoi Group . The batholith is made up six major units: Part of the batholith is thought to be covered by thick sedimentary deposits such as those of Iglesia Basin . This geology article is a stub .

Coastal Batholith of central Chile The Coastal Batholith of central Chile is a group of plutons in the Chilean Coast Range of Central Chile appearing contiguously from 33° S to 38° S. At a latitude of 40° S an outlying group of plutons of the batholith appear in a more eastward position in
9-678: The Andes . Together with the Elqui-Limarí Batholith and the Colangüil Batholith , the Coastal Batholith of central Chile is a remnant of the volcanic arcs that erupted the volcanic material of the Choiyoi Group . During the Permian the zone of arc magmatism moved from the Coastal Batholith 350 km inland reaching San Rafael about 280 million years ago. The batholith is emplaced amidst metamorphic rocks belonging to
