| Study area is located in the South Qinling fold belt, which folds, faults and other structures in so developed, the ore has created excellent conditions for Shan(Yang) Zha (Shui) Xunlei(Yang) expensive, non-ferrous metal mine area will be located. In recent years, the study area (Yin Changgou-Tomb ditch, pond area) and surrounding areas (ZhenXun in Southern shaanxi DaHe dam-Goddess of Mercy Temple, Fengtai, MaYuan), and other found a lot of lead, zinc and copper and silver polymetallic deposits. Through analysis of the region and around the mining area, the geological characteristics of the study area and the ore body reached the following understanding of ore-controlling factors.Exposed area is mainly Silurian strata-Devonian, Silurian, lithology is a combination of fine-grained clastic rocks, mainly dark gray slate with charcoal gray phyllite, carbonaceous siliceous rocks and carbonaceous board folder containing carbon crystalline limestone rock. The bottom of the Devonian sedimentary rocks developed a set of hot water, lithology is mainly calcarenite gray chert conglomerate, pebbly sandstone, the upper coarse-grained lithology with fine sandstone, siltstone, pebbly coarse feldspar and quartz sandstone biogenic limestone, sandy dolomite and so on.Phenomenon as a major regional tectonic folds and faults, south anticline Kuanping role of a strong recovery, form more complex, often folding to form a different class times, early synsedimentary fault fault mainly formed during the stretching exercises at the regional. According to the fault, rotation spot broken line, en-echelon veins, S-C foliation inferred structures such as the region is mainly affected by north-south tectonic compression control and sinistral shear effects.Sulfur isotope studies have shown ore than a single source for the sedimentary origin.Individual homogenization temperature (Th) are 95～135℃with the temperature between the mineralization characteristics. Salinity of 4.9～11.5wt·% NaCI, and more focused on the 7～10wt·% NaCI. Normal seawater salinity (3.5 wt·% NaCI) about 2 times.Ore zone of control by many factors, including the structure, and rock layers are equal, there is anticlinorium ore generally Fu (Ⅱgrade fold) secondary syncline (Ⅲgrade fold) of the turn end of the faults of mine Control of the body as follows:①the control of sedimentary basins, and thus control the distribution of ore bodies;②provide access for the ore-bearing hydrothermal;③the transformation of ore enrichment. West Chahe group formation in the lower and the residence district, and is controlled seam position.Dolorudite chert, pebbly sand, and chert debris is the main ore dolomite rock. Basin in terms of forming characteristics of rock or mineralization with the surrounding area were significantly different, reflecting the lithofacies, lithology control on the mineralization effect. The region has gone through the normal ore ore-deposit hot water deposition the role of structural transformation.Contrast that region by studying the deposit is a deposit-modified type polymetallic deposits.
