摘　　要：为了研究阜新地区火山型金矿的成矿条件和控制因素,通过对于家沟金矿所处的区域地质背景、矿区和矿体地质特征、矿体赋存的空间方式以及金矿工作区的化探异常特征的论述,分析矿体的成矿条件和控制因素。于家沟金矿产于中古界雾迷山组和中生界侏罗—白垩系义县组二者的接触带或火山岩中。褐铁矿化蚀变硅质角砾岩是本区寻找金矿的重要找矿标志。对今后在火山区的找矿工作具有一定的参考价值和指导意义。In order to reaserch the ore-forming conditions and control of orebodies factor of Fuxin gold deposit.Through for Yu Jia Gou gold mine in which the regional geological setting,mining and ore geological characteristics and ore body space approach,discusses the work zone of gold geochemical anomalies,analysis of the ore-forming conditions and ore-contorlling.Yu Jia Gou gold deposit in Mesoproterozoic Wumishan and Mesozoic Jurassic-Cretaceous Yixian Formation,the contact zone between the two contact zones,or volcanic rocks.Limonite alteration of siliceous breccia is important for looking for gold prospecting indication in this area.It will has some value and significance to the future prospecting in volcanic areas.
