摘　　要：旭阳屯金矿床属中低温变质热液矿床,矿石是以含金石英脉型和含金蚀变岩型为主。矿床规模为小型,矿床处于华北板块北缘东段多金属成矿带上,矿床含矿热液流体沿着北东向压扭性断裂上侵,具有多期脉动形成特点。矿床矿体多赋存在太古界老牛沟岩组区域变质岩中。矿体主要受硅化蚀变体和北东向压扭性构造控制。矿床外围和深部找矿潜力巨大。The Xuyangtun gold deposit belongs to a medium low temperature metamorphic hydrothermal deposit,and the ore is mainly composed of gold-bearing quartz veins type and gold-bearing altered rock type.The deposit is small in scale and located on the eastern section of the northern margin of North China Plate s polymetallic metallogenic belt.Ore-forming hydrothermal fluids ascended along northeast-trending compression and torsional faults,exhibiting multi-stages pulsating formation characteristics.The ore deposits and bodies are mostly found in metamorphic rocks of the Archean Laoniugou Formation.The ore body is mainly controlled by silicified alteration bodies and northeast-oriented compressional and torsional structures.There is significant exploration potential exists in the peripheral and deeper parts of this deposit.
