... In contrast, the No. 1 porphyry Cu-Au deposit in the Xiongcun district (Tibet, China) has abundant pyrrhotite, reduced fluids (CH 4 ≫ CO 2), and a relative lack of highly oxidized minerals, which are indicative of low fO 2 conditions ... The relation between Cu/Au ratio and formation depth of ... ... . Life spans and thermal evolution of hydrothermal systems are of fundamental metallogenic importance. We were able to establish the chronology and cooling history of the Zaldívar porphyry copper deposit (Northern Chile) by applying a combination of different isotopic dating methods in minerals with different closure temperatures, including 40Ar/39Ar geochronology and zircon fission track ...

Copper was mostly removed from the sericitic capping, but iron, molybdenum, and gold were relatively immobile during supergene leaching.Interpretation of the space-time patterns and relations of the mineralization, alteration, volcanism, and intrusion allows reconstruction of the depositional environments of the El Salvador porphyry copper deposit. Constraints on gold and copper ore grades in porphyry-style Cu-Au ± Mo deposits are re-examined, with particular emphasis on published fluid pressure and formation depth as indicated by fluid inclusion data and geological reconstruction. Defining an arbitrary subdivision at a molar Cu/Au ratio of 4.0 × 104, copper-gold deposits have a shallower average depth of formation (2.1 km ... 1. Introduction. Porphyry copper deposits (PCDs) are the world's largest source of copper and a major source of molybdenum, gold and silver (John et al., 2010).They share similar hydrothermal veins and alteration types and distributions regardless of wall rock types and formation ages (Gustafson and Hunt, 1975).Widely accepted genetic model involves exsolution of magmatic fluids from ... Metal origin and fluid evolution in the Zaldívar porphyry copper deposit, Chile. An orthomagmatic model. 2002, 165 páginas. ISBN: 90-807115-1-9. Departamento de Ciencias Geologicas. Facultad de Ingenieria y Ciencias Geologicas. Universidad Catolica de Antofagasta. Avenida Angamos 0610. Antofagasta, Chile. E-mail: [email protected] Two key factors are proposed for the fluid evolution responsible for the large size of the gold‐rich porphyry copper deposit of Duobuza: (i) ore‐forming fluids separated early from the magma, and (ii) the hydrothermal fluid system was of magmatic origin and highly oxidized. Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those f...
