The Jiaoshanzhai gold deposit in Xunyang County,Shaanxi Province is tectonically located in the Liufengguan-Jinjiling fold bundle of the South Qinling Indochinese fold belt of the Qinling fold system.The gold deposit occurs in the gry-green sericite silty phyllite of the second lithologic member of the Upper Silurian Shuitonggou Formation,with lenticular and vein-like output.The gold orebody in the area is characterized by multi-stage and multi-system mineralization by strata,structure and hydrothermal activity.Following the epigenetic stage of compaction and cementation,the source layer with ini-tial enrichment of ore-forming elements is formed,and then the ore-forming process is formed by late superposition and transformation,and multiple transformation of metamorphism and tectonic hydrothermal activity.The genetic type of the de-posit belongs to the sedimentary and reformed type(hydrothermal)gold deposit.
