摘要
主要研究了康古尔金矿的流体包裹体的氢、氧同位素组成以及硫、铅和碳同位素组成，结果表明该金矿床主矿化阶段成矿流体以变质水为主，晚期以大气降水为主，总的表现为下部上升流体与残部大气降水混合成矿特征。该矿床的成矿物质具深源性，主要来自上地幔或下部地壳，是一种火山岩区剪切带蚀变岩型金矿床。
This paper deals mainly with the hydrogen, oxygen, sulfur, lead and carbon isotopic compositions of the Kanggull gold deposit. The results show that metamophic water is dominant at the major stage of mineralization and meteoric water is dominant at the late stage. The ore-forming material is of deep source, coming from the upper mantle or the lower crust. The deposit is a shear belt-hosted altered rock-type gold deposit in the volcanic rock area.
