Geological characteristics and metallogenic stages of the Pongo iron polymetallic ore deposit in Peru

From Lima, the capital of Peru, to Chala City, there is a 400km long mineralization zone along the Pacific coast. In this zone, there are a number of iron, copper, gold deposits. The copper-gold deposits possess the special IOCG type characteristics, whereas the iron deposits are mainly of skarn type. Pongo is a huge iron deposit. The deposit is located in the Western Cordillera near the western edge of the depression of ICA to Nascar. The deposit is accompanied by copper-gold mineralization. This deposit not only has skarn specialty but also has IOCG features. The authors summarized the geological factors of the deposit and indicated an excellent copper-gold potential. It is also pointed out that the main iron mineralization and the gold-copper sulfides are different in stage and space.
