摘　　要：西峡县寨子沟金矿区域上主要受商丹断裂带次级断裂的构造控制影响。通过对研究区内矿脉和围岩进行微量和稀土元素地球化学特征进行分析,认为研究区矿床形成于相对还原的环境,其围岩和地层岩石中成矿元素均来自同一源区或赋矿地层受到后期变质成因流体的影响,成矿物质来源具有多源性,主要来源于岩浆作用和深部变质热液流体因素。控矿因素主要包括次级脆性断裂构造、赋矿地层和岩浆作用等。Xixia Zhaizigou Gold Deposit is controlled by secondary faults of Shangdan Fault Zone.Through the geochemical characteristics of the trace elements and rare earth elements in the veins and surrounding rocks in the study area were analyzed,and it was concluded that the deposit in the study area was formed in a relatively reduced environment.The ore-forming elements in the surrounding rock and stratigraphic rocks in the study area are all from the same source area,or the ore-hosting strata are influenced by the later metamorphic fluids.The ore-forming materials are from multiple sources,mainly from the magmatism and deep metamorphic hydrothermal fluids.The ore-controlling factors mainly include the secondary brittle fault structure,ore-bearing strata and magmatism.
