摘　　要：金厂河地物化综合异常由隐伏的与矽卡岩有关的多金属硫化体引起。矽卡岩可能是岩浆汽液沿节理裂隙向上喷流与碳酸岩发生接触交代所形成。矿体主要受节理裂隙控制。富含铁质的中性—基性岩浆岩与矽卡岩生成有关。提出金厂河矿床成矿阶段。The Jinchanghe Geological, Geophysical and Geochemical comprehensive anomaly is caused by the buried multimetallic sulfide related with skarn. The formation of skarn maybe the result of contact metasomatism of carbonate rock caused by the magmatic gas and fluid effusion upwards along the joint fissure. The ore deposit is mainly controlled by the joint fissure. The formation of skarn is related with the intermediate - basic magma rich in Fe. In this paper, we put forward the possible metallogenetic stage of Jinchanghe ore deposit.
