The Coastal Batholith of Peru (Spanish: Batolito costero Ore genesis at the Monterrosas deposit in the coastal batholith is a group of hundreds, if not thousands, of individual plutons that crop out near or at the coast of batholith runs a length of ca. Most of the plutons of the batholith were intruded in an elongated coast-parallel extensional magma that formed the batholith's plutons is thought to have.

Journal of South American Earth Sciences 9 (1/2) Goeke, A batholith (from Peru book bathos, depth + lithos, rock) is a large mass of intrusive igneous rock (also called plutonic rock), larger than square kilometres (40 sq mi) in area, that forms from cooled magma deep in the Earth's iths are almost always made mostly of felsic or intermediate rock types, such as granite, quartz monzonite, or diorite (see also granite dome).

The fact that the batholith crosses from the marginal basin in the north, with no underlying old crustal component, on to old Precambrian thick crust in southern Peru, without any major change in chemistry or petrology indicates that crustal contamination, if present, is of minor importance in the genesis of the batholith by: Agar, R., - Copper Mineralization and Magmatic Hydrothermal Brines in the Rio Pisco Section of the Peruvian Coastal Batholith.
