Ore fluid and geochemical characteristics of Yanfangwan Pb-Zn deposit in Shaanxi Province
摘要
Abstract
Yanefangwan Pb-Zn deposit is a small Pb-Zn deposit of Fengtai ore-deposit-cluster area in Taibai county, Shaanxi Province and a few geological works have been done. Ore fluid of Yanfangwan Pb-Zn deposit is in medium-low temperature and low salinity and contains CO2, N2, CH4 etc. of the reductive gas system characteristic of hot saline. The fluid inclusions are mainly water solution, COz-H2O-NaCl and pure CO2, the three kinds of inclusion which are immisible. The homogenization temperature is higher than that of Bafangshan-Erlihe Pb-Zn deposit that may be related to intrusion of Xiba rock body. H,0 iso-topic composition is characterized by mixture of magmatic water and metamorphic water, C,O isotopic composition by normal Silurian marine carbonate rock and Pb isotopic composition by mixture of Pb sourced from orogenic belt and that of upper crust. Isotopic characteristics of Yanfangwan Pb-Zn deposit differs obviously from those of large Sedex Pb-Zn deposits in the same area and is inapropriately classified into the hot water sedimentary large Pb-Zn deposit.关键词
