摘　　要：复兴村金矿床位于白山-老岭成矿带上,主要赋存于元古代老岭群珍珠门组白云质大理岩中,矿体严格受NNE、NW向断裂构造控制。从矿体形态、产状、规模及品位,矿石类型、组成及组构,矿化期次、矿化阶段的划分,围岩蚀变等方面论述了矿床的地质特征。通过对矿石S同位素分析和成矿温度、成矿时代研究表明,金成矿物质来源于地层和岩浆岩,成矿温度为中低温,成矿时代为燕山晚期。认为该矿床成因类型为与燕山晚期岩浆活动有关的中低温热液矿床。同时,还初步建立了成矿模式,并进行了成矿预测,为在该区开展地质工作提供帮助。The Fuxingcun gold deposit,located in the Laoling metallogenic belt,it occurs in form of dolomite marble of Zhenzhumen fraction of Laoling group of Proterozoic,The ore-body is controlled by NNE、NW strike fracture zone strictly.According to the morphotype,occurrence,size and grade of the orebody,ore types,mineral association and fabric,division of the mineralization periods and stages,wall rock alteration,the geological features of caepiabu gold deposit are illustrated.The main controlling factors are stratum,fracture structures and magma activites,among them fracture structures is the most controlling.Based on the analysis of S isotopes and the study of mineralization temperature and mineralization time,it is found that the metallogenic elements are from strata and magmatic rock,the temperature of mineralization is meso-hypabyssal middle-epithermal type gold deposit of Later Yanshan Epoch.At the same time,but also has induced the main prospecting symbol,for seeks this type gold deposit in this area to provide the help.
