Geological Features and C-H-O-S-Pb Isotopes at the Zhazixi Sb-W Deposit

Abstract

The Zhazixi Sb–W deposit in the Xuefeng arc metallogenic belt, South China, is one of the Sb deposits in Precambrian strata. The sources of the ore-forming fluid and the metallogenic material, as the bone of contention in geochemical field, are researched by means of geological features and C-H-O-S-Pb isotopes. According to the isotope analysis of carbon, hydrogen and oxygen, most of the fluids derived from magmatic water and meteoric water in the Zhazixi Sb–W deposit. The result of sulfur and lead isotopes shows that the metallogenic material of Sb derived from Banxi group strata, and W derived from deep magmatic rock in the Zhazixi Sb–W deposit. The Zhazixi Sb–W deposit is a Yanshanian polygenetic compound deposit.
