Evolution of volcanism and hydrothermal activity in the Yanacocha Mining District, northern Perú

Creator:

Longo, Anthony A.

Abstract:

The Yanacocha Mining District in northern Perú is considered the largest group of high-sulfidation style epithermal gold deposits in the world. District-scale geologic mapping coupled with detailed 40Ar/39Ar geochronology, geochemistry and petrography establish the volcanic history of the area and analyze the temporal and spatial evolution of volcanism, hypogene advanced...
