摘　　要：豫西地区是中国仅次于胶东地区的第二大产金基地,而熊耳山地区则是豫西重要的黄金成矿带之一。研究区内燕山期五丈山、花山、合峪三大花岗岩体与区内金的成矿作用有着十分密切的关系。从三大岩体与金矿分布、成矿时间、物质来源等方面研究了二者之间的成生关系。研究认为:五丈山、花山、合峪花岗岩体与区内众多金矿床(点)显示出同空间的分布关系;岩体和金矿床均形成于燕山期,成矿与成岩在同阶段或稍晚于成岩阶段;在岩体和矿床铅同位素、硫同位素、氧同位素特征方面,显示出金成矿与五丈山、花山、合峪花岗岩体的同源关系。Western Henan province is the second largest gold producing base,only superior to Jiaodong Region, and Xiong＇ershan area is one of the most important gold metallogenic belts in the base.The three granite rockmasses of Wuzhangshan,Huashan and Heyu in the research area correlate with the gold mineralization closely.In this paper, we analyse their genetic relationship according to their distribution,mineralization time and material sources,etc.It is supposed that：Firstly,the three granite rockmasses distribute isospacely with gold deposits in the study area;Secondly,the three granite rockmasses and gold deposit were formed during Yanshan Epoch,and mineralization ocured at the same time with or a little later than diagenesis;Thirdly,through lead isotope,sulfur isotope,and oxygen isotope analysis,we indicate that gold deposits in this area are syngenetic with the three granite rockmasses.
