Abstract

The study area is located in western Peru, in the province of Chincha, department of Ica, 175 km SE of Lima. The Cerro Lindo deposit is located in a NW-trending belt formed by volcanic sedimentary rocks of the Huaranguillo Formation belonging to the Casma Group (Albian-Cenomanian). 

Later, the volcanic was intruded by the Coastal Batholith, of granodioritic, tonalitic, and dioritic composition with calc-alkaline affinity. Medium grade metamorphism occurs at the contact of the intrusive with the volcanic, and finally porphyritic dikes intrude the volcanic of the Huaranguillo formation.

The lithogeochemistry performed is intended to help understand the origin and evolution of the geological processes present in the formation of the different lithologies of the Cerro Lindo deposit and, above all, to determine alteration trends and from this to establish signatures in the rocks most related to mineralization.
