Geological Features and Ore-control Factor of Fuxingcun Gold Deposit in South Jilin

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.
