The Elqui-Limarí Batholith is a group of plutons in the Andes of Chile and Argentina between the latitudes of 28 and 30° S. The plutons of the batholith were emplaced and cooled in the Late Paleozoic and the earliest Mesozoic. Some of the plutons were emplaced in a context of crustal thickening related to the San Rafael orogeny.
Together with the Chilean Coastal Batholith and the Colangüil Batholith the Elqui-Limarí Batholith is a remnant of the volcanic arcs that erupted the volcanic material of the Choiyoi Group.
