摘　　要：对产在河南省内乡地区五朵山花岗岩体内外接触带的金矿床(点)的地质构造背景、矿床地质特征、控矿构造及成矿流体等进行了较为全面的阐述,认为花岗岩与金矿的关系不是直接的而是间接的,构造对金矿的控制是第一位的,区内所有的矿化都受断裂构造的控制。五朵山岩体周围,尤其是西南部的岩体内外接触带、断裂构造发育区、富含黄铁矿和金属硫化物的地段为金矿的有利找矿区。This paper gives a relatively complete description of the structural setting, geological characteristics, ore-controlling structures and ore fluids of the gold deposits （occurrences） in the endo- and exocontact zones of the Wuduoshan granite intrusion in the Neixiang area, southwestern Henan. The authors think that the relation between granite and gold deposits is not direct but indirect, while the control of faults on gold deposits is most important and all of the mineralizations in the area are controlled by faults. The endo- and exocontact zones of the intrusion, areas of fault structure and zones with abundant pyrite and metal sulfides around the Wuduoshan intrusion, especially in the southwestern part of the intrusion, are areas favorable to looking for gold deposits.
