Comparison of oneand two-stage models of copper-porphyry deposits formation
In: Moscow University Bulletin. Series 4. Geology, Issue 4, p. 31-38
Models of copper-porphyry deposits formation examined from the petrological and geochemical points of view. The principal differences between the models are time and mechanism of sulfide ore precipitation and the composition of ore-bearing fluid. It is shown that copper-rich fluid inclusions contain insufficient amount of sulfur for sulfide ore formation and it have to be independent source of sulfur for copper-porphyry deposits formation.
