摘　　要：对河南省外方山地区前河、店房、西灶沟等金矿床矿石稳定同位素组成进行了研究，该区金矿矿石铅、硫、氢氧同位素组成与燕山期花岗岩基本一致，反映了金矿成矿与燕山期岩浆活动有密切的成因联系。各矿床矿石稳定同位素组成也有一定的差别，这与成矿时的地质环境有关。Based on the study of stable isotopes in Qianhe, Dianfang, Xizaogou gold deposits in Waifangshan area, it indicates that the compositions of Pb, S, H, O isotopes in gold ores have close genetic relation with magmatic activities of Yanshan Period. The compositions of stable isotopes in each deposit have some differences, which are related to the geological enviroment during the mineralization.
