| 摘 要： | 祁雨沟金矿是典型的爆破角砾岩型金矿。系统地论述了其成矿地质背景、矿床地质、地球化学特征、及其成因意义。根据围岩蚀变和矿物包裹体温度、成分的研究,确定了矿床形成的物理化学条件及其各阶段的演变;通过氧同位素研究证明了成矿溶液的来源由早期岩浆水转变为晚期大气降水;用硫、碳和铅同位素组成说明成矿物质的复杂来源。以板块构造理论为指导,建立了矿床的形成模式,并指出找矿方向。

| Abstract: | Qiyugou gold ore deposit is a typical explosive breccia type gold deposit. The metallogenetic geological setting ,geological and geochemical characteristics of the deposit and its genetic significance are systematically stated in this paper. The physicochemical conditions and the evolution in each stege of the ore forming process is designated based on the study of wall rock alteration and of the temperature and composition of fluid inclusion in mineral. The isotopic composition of oxygen shows that the origin of the ore forming solution was turn from magmatic water in early stage to circulated meteoric water in later stage. The isotopic composition of lead,sulphur and carbon demonstrate a complex source of ore forming material.Genetic model of Qiyugou type gold deposit is proposed and prospecting direction was pointed out according to plate tectonic theory. |
