摘要
本文对乌拉山金矿床的Ｈ，０，Ｃ，Ｓ稳定同位素组成特征进行了论述。认为其金质是多源的，但主要来源于太古界乌拉山群。成矿流体早期的变质水，晚期的岩浆水，随着成矿作用的进行大气降水逐渐增多，并起了重要作用。
The formation of Wulashan gold deposit is controlled bythe multiple metamorphsm anddeformation in shearing zone and its sub-shearing zone,The physical chemistry grade andstructural geochemistry formed by shearing is main mechanism of metallogeny.This paper al-so describe the characteristics of hydrogen,oxygen,carbon and sulphur isotopic composition,which suggest multiple resources of gold ore materials,but mainly coming from WulashanGroup,The early metallogenic fluid is metamorphic origin,the late fluid is from magmaticand meteoric water.With the progression of metallogenesis,meteoric fluid continuously in-creases,it has vital role in forming and evolution of ore deposit.
