摘要
通过对张宣地区金矿床硫、铅等稳定同位素地球化学研究,阐明该区形成金矿的主要物质来源为太古界桑干群地层,其成矿时代为燕山运动时期,基于矿床地质及硫、铅、氢、氧等稳定同位素研究,建立了本区金矿的成矿模式.
The geological characteristics of lead and sulfur isolope of the gold deposits in Zhang Xuan region are studied and the minerogenetic model of this area is esteblished in this paper. Basd on the isotopic data and the source of sulfur, lead and gold come from Archean strata. The lead isotope composition shows that the mineralization epoch is during Yanshan Movement. Hydrogen-Oxygen isotope compisition of the hydrothermal solution of this erea is predominantly composed of undergr ound water, ariginalwater and magmatic water
