The Miocene Morococha District, Central Peru--Large-Scale Epithermal Polymetallic Overprint on Multiple Intrusion-Centred Porphyry Systems

摘要

In the world-class mining district of Morococha, epithermai polymetallic replacement bodies and veins overprint porphyry mineralisation and skarns related to subvolcanic intrusions of Miocene age, thus indicating ore formation in two different environments, separated in time or forming a continuum.
