摘　　要：辽宁西安村铜钼矿床地处抚顺-新宾新太古代、中生代铁、金、铜成矿带,周边多金属矿床、矿点密布,成矿地质条件优越。通过于区内开展地质填图、轻型山地工程揭露以及化探数据分析等工作,探讨了矿区地质特征及找矿前景。西安村矿床类型主要为矽卡岩型的铜多金属矿床以及斑岩型钼矿床,英云闪长片麻岩内近东西和北东向断裂,Au、Ag、Cu、Mo、W异常区和近东西向和北东向负磁异常为重要的找矿标志。区内化探异常东南部已发现中铜钼矿床,且已发现一定规模钼矿存在的磁场特征,加之地层、构造和岩浆岩成矿条件优越,该区找矿潜力较大。The Xiancun copper-molybdenum deposit in Liaoning Province was located in Fushun-Xinbin Neo-Archaeozoic and Meso-zoic iron,gold and copper metallogenic belt,and the surrounding polymetallic deposits and ore spots were densely covered with favor-able metallogenic geological conditions.Through geological mapping,light mountain engineering exposure and geochemical data analysis in the area,the geological characteristics and prospecting prospects of the mining area were discussed.The Xiancun deposit was a skarn type copper polymetallic deposit and porphyry type molybdenum deposit.The near-east-west and NEE trending faults in the dio-rite gneiss,theAu,Ag,Cu,Mo,W anomaly areas and the near-east-west and NEE trending negative magnetic anomalies were important prospecting indicators.In the southeast of the geochemical anomaly,a medium copper and molybdenum deposit had been found,and the magnetic field characteristics of molybdenum deposits of a certain scale had been found.Combined with the favorable metallogenic con-ditions of strata,structure and magmatic rocks,the area had great prospecting potential.
