| Zhanshun Cu-W Multi-metal deposit is in the location of the northern of Elashan mountain belt, the west of Mawengen, and the northeast of Zhanshun, which seated at the collision combination of West Qinling and East Kunlun orogenic belt. Metallogenic belt belong to the province of East Kunlun Precambrian, Paleozoic, Mesozoic gold and copper zinc iron ore belt. The deposit is a lead, zinc, metal deposits, which mainly composed of copper, tungsten, silver, and gold, contains Shalongguakong and Zhanshunnan two regions.Shalongguakong is a skarn deposits, through analyze the original rock of the skarn by c-n-f diagram, K-A diagram and A-C-(FM) diagram, we found that original rock of skarn are marly sedimentary rocks and carbonate rocks. The useful elements in the ore are copper, silver, arsenic, Cu:5.0~5.9%, Ag:33~34g/t, As:1.56~1.58%,Ag and As were positively correlated. Through the trace elements analysis of diorite we found that Ag contents up to 0.175μg / g, Cu contents of up to 142.91μg / g, Ag and As are far exceed that of the Chinese continental crust abundances, while the limestone Ag only 0.028μg / g, Cu only 43.97μg / g, the preliminary view that diorite provided material for the ore source.The type of Zhanshunnan's Granodiorite is mixed of I type and S type, ore bodies occur in granodiorite fracture zone, Cu:1.58%, Ag:17g/t, Au:0.87~1.2g/t, trace elements analysis conclude that granodiorite provided Ag for the ore source, The source of Cu needs further study.Combined the above recognizing with Cu, W, Ag, Au, Pb, Zn soil geochemical anomalies, this area has the potential to find Cu, Ag, Au associated with W, Pb, Zn multi-metal deposits and delineates prospecting targets.
