摘　　要：刺猬沟金矿 ,是我国典型的火山岩型金矿之一。矿床产于破火山口内 ,矿体严格受破火山口内放射状断裂系统控制 ,成矿热流体主源于火山岩浆期后分异的热液。成矿阶段和金银比等与世界 30多个近地表金矿相似。地质、地球化学、物理化学和矿体等特点说明 ,该矿床属火山岩浆期后中 -低温的热液贫硫化物脉金型金矿床。Ciweigou gold deposit is one of the typical volcanic rock gold deposits in the country.The ore deposit occurs in the broken vlcanic orifice;the orebody is controlled strictly by the radioactive fracture system in the broken volcanic orifice;and the main source of mineralized hot fluid is the volcanic magma postsplitting thermal solution.The mineralizing phase and gold to silver ratio are similar to more than 30 near by surface gold deposit in the world.it shows from geological,geochemical,physicochemical and orebody’s characteristics that this ore deposit belongs to hydrothermal sulfide poor vein gold deposit of volcanic postmagma medium low temperature.
