Fluid Inclusion Studies on Quartz Associated with Massive Ores of the Paleoproterozoic Carbonate-hosted Pb-Zn Deposit at Balaria, Rajasthan: Possible Evidence for Fluid-mixing

摘要

Mixing of metal-rich connate waters derived from evaporative seawater with local sulfide-rich water is postulated as the mechanism of ore deposition in many Phanerozoic carbonatehosted Pb-Zn deposits. The study of the Paleoproterozoic Balaria deposit of the Zawar belt of Rajasthan that hosts structurallycontrolled, stratabound Pb-Zn mineralization, provides insight into the nature of fluids in quartz that is closely associated with massive Pb-Zn ore.
