Abstract: Huanglong Goldfield is located in the eastern part of Baishuijiang-baihe fold bundle，indosinian fold belt of South Qinling, with Liufengguan-Jinjiling fold bundle in the north and Ziyang-zhongfeng in the south. The gold orebodies are strictly controlled by stratigraphic lithology, ductile shear zone, and vein rock. The ore type is altered rock type of gold deposit, and the alteration is mainly silicification, sericitization, pyritization and so on. Based on the previous analysis, the authors hold that regional tectonic movement provided powerful motivation and favorable concentration area for mineralization. Volcanic sedimentary and clastic sediments were the original sources of gold deposit. The superposition and enrichment of the thermal sources, hydrothermal solution and deep substances brought by the intrusive rock in Indosinian period, and the ductile shear structure finally co-formed the gold deposits. In addition, this paper described in details the ore-controlling factors and summarized such six aspects of ore-prospecting criteria as stratigraphic lithology, structure, vein rock, wall-rock alteration, geomorphology and geochemistry.
