Abstract：The Zhuyuangou ore deposit is a large-sized tungsten-molybdenum deposit discovered in recent years in East Qinling area. Its geological features were studied in this paper on the basis of the geological background. The distribution of ore bodies is related to folds, fractures, lithology and intensity of wall-rock hydrothermal alteration in the ore district, and the ore bodies are controlled by the Huangbeiling anticline and the endo-exocontact zones of the northwest-pitching Shibaogou porphyritic adamellite intrusive. The ore deposit is genetically of the porphyry-skarn type. Ore-searching criteria and prospects are indicated in this paper, which are of some significance for further ore-searching work.
