Bulong gold deposit formed in late-Permian is a small scale gold deposit in Southwest Tianshan，Xinjiang.Orebodies are mainly located in detachment fault belts between layers of Devonian purple，grey-black sandstones and siltstones.Through a comparative research on low metamorphic clastic rock gold deposit in Central Asia，Sawayardun gold deposit in Southwest Tianshan and Bulong gold deposit，a crucial conclusion is made that Bulong gold deposit is a low metamorphic clastic rock gold deposit type.Devonian Kezrtage formation clastic rock，which has a distinct geochemical feature of high Au coefficients of concentration and variation，is an origin of ore elements.Bulong fault is considered as a transport and precipitation fault.Metallogenic model is established according to analyzing ore-controlling factors and unconformable faults between Devonian and Carboniferous strata and gray-black phyllitic sandstones are advised to prospect ores.
