Iglesia Basin (Spanish: Cuenca de Iglesia) is a sedimentary basin located in northern San Juan Province, western Argentina. It is thought to be a piggyback basin.[1] Its sedimentary fill is of Neogene to Pleistocene age and has an estimated maximum thickness of 3.5 km.[1] There are hot springs in the eastern part of the basin.[1] The rock under the sedimentary fill is interpreted to be in part composed of plutonic intrusions belonging to the Tocota pluton, which in turn is a part of a larger group of plutonic intrusions known as the Colangüil Batholith.[2]
