Illescas Batholith

Illescas Batholith is a geological complex located in Uruguay made up of various plutons including rapakivi granite and quartz syenite. The batholith is of Late Paleoproterozoic age.[1][2] The batholith originated and was emplaced in an anorogenic tectonic setting during a period of extensional tectonics.[2] The batholith intrudes the Valentines Granulitic Complex of Nico Perez Terrane.[2] The Florida dyke swarm is related to the Illescas Batholith.[3]
