Cordón de Lila

Cordón de Lila is a mountain range of the Andes located in northern Chile, south of Salar de Atacama. Geologically it is made up of a batholith of Cambrian and Ordovician age. The rocks of Cordón de Lila are the result of pre-Andean magmatism that occurred during the Famatinian orogeny. The compositions of the plutonic rocks are granodiorite and monzogranite that are either metaluminous or marginally peraluminous. These rocks are remnants of the magmatism along the western rim of the Famatinian orogeny.
