Abstract: Abstract：The Leng（shuigou）-Chi（gou）-Se（hepu） gold molybdenum and copper belt of Zhashan area in Shaanxi Province is located in southern Zhashan area and lies in the middle of Xiaomaoling-Douling Proterozoic island chained uplift belt and at the junction of the middle and south Qinling Mountains. With the east-west length of 35.7 km and the north-south width of 7.6 km, this belt contains multiple gold molybdenum and copper deposits related to intermediate and acid magmatic activities of Yanshanian period. Geology, ore body, alteration and mineralization regularities of the Lengshuigou gold copper deposit, the Chigou gold and molybdenum copper deposit, the Sehepu copper deposit and other main deposits are summarized in this paper. They are controlled by the main porphyry rock. On the whole, from the porphyry body to surrounding rocks, there appears molybdenum in the inner part , copper in the outer part and gold in the distal part, constituting a porphyry type–skarn type-cryptoexplosion breccia type-tectonic altered rock type gold molybdenum copper metallogenic series. The discovery of the Leng-Chi-Se gold, molybdenum and copper belt provides direct evidence in search for porphyry molybdenum-copper deposits in middle and south Qinling Mountains, and also broadens the ore-prospecting train of thought and space in Zhashan area.
