Abstract: Hanshan gold deposit is a great gold deposit to be found in North Qilian mountains during the last decade of the twentieth century.By analysing ore-forming setting,geological features,ore-forming marks and ore-control factors of the deposit,authors consider its ore-forming matter mainly comes from calc-alkaline intermediate-acidic pyroclastic rocks of island arc,ore-bodies are controlled by multi-degree faulted system and mainly occurrence in strongly schistosity of ductile-brittle shear zone,mineralization happened in or after the period of intermediate-acidic magma positioning and solidify ing during the compression-extend climacteric of coliision orogenesis,the heat-driving force mainly comes from deepmag machamber or intermediate-acidic intrusive bodies.The genetic type of the depositis at ectonic-altered gold deposit related to volcanic rocks.From what has been discussed above,authors summarize and induce met-allogenic model and comprehensive prospecting criteria of the deposit.
