Abstract: West Qinling orogenic belt is an important metallogenic belt in China, where discovered dozens of large and super-large gold deposits. The Dangqinggounao deposit is located in the southern subzone of EW-orientated complex structure zone in West Qinling and the core of Dangqinggounao secondary anticline in Jishishan anticlinorium, which is a new discovered district with good metallogenic prospects in recent years. The Dangqinggounao deposit has the silimar horizon to the Dashui gold deposit in Maqu Country, but it has low degree of geological work. After carrying out the 1:50000 stream sediment survey in Dangqinggounao area, 4 abnormal combination have been delineated. The HS-1 abnormal is the combination of Au, Bi, Cu, As and W, with anomaly area of 11.5 km² and exceptionally well element fitness. And the HS-1 abnormal has been verified by the 1:10000 soil geochemical survey and exploratory trench engineering. And then, one gold-tungsten mineralization belt of 1.5-2 km long and 0.6-0.7 km wide has been found, where 3 gold orebodies and 2 tungsten bodies have been delineated, with good gold-tungsten prospecting prospects.
