The study area is located in Fuyun County,Xinjiang the Kala An-Qiakuerte vicinity,Tectonic background in the Junggar arc-basin system Tanggubale-Karameh the Palaeozoiccomposite ditch arc belt of Xiemisitai–Kulankazigan to Palaeozoic composite island arc beltat the eastern end.North to the Irtysh fracture and Mayinebo fracture with Altai arc-basinsystem,South to Qingshui-Hongliuxia-Yiwu fracture,The region has good mineralizationconditions.Magmatic rocks of the study area geochemical data for major and trace elements, rareearth elements and isotopes comprehensive analysis of magmatic rocks of the study areaevolved from homologous mother slurry formed in the island arc subduction zoneperaluminous rock series. Early subduction in the Early Devonian, mainly for the nature ofthe oceanic crust basalt along the structural weak with bottom split up, the formation oftholeiitic basalt series. With the passage of time and dive depth increases, molten magmadifferentiation by the base-neutral-acid rock, tholeiitic basalt series-calc-alkaline series-high potassium series changed regularly.Study area Ag, Sn, Pb, Cu, As, Sb, Mo element enrichment factor greater than1, theregional characteristics relative enrichment. Au, Cu, Ni, Sb, Mo element coefficient ofvariation greater than1, the coefficient of variation of Au greater than3, great vision in thelocal enrichment of mineralization. Au, Cu element anomalies are mainly distributed in thematrix-neutral rocks Series, tholeiitic series-calc-alkaline series, found mine (of) points,near the southeast of the study area diorite, better Deposit Prospect; ore of Fe (of) pointdistribution the next Devonian chomo Bath set, sandstone and tuffaceous sandstone themiddle Devonian Wulubasitao set, the formation of sedimentary iron the deposit goodprospects.Basis with other deposits in contrast,Upper Carboniferous the Batamayineisan group,The Lower Carboniferous Jiangbathtao group,The Lower Carboniferous the Heishantou group,Lower Devonian Zuomubathtao group pyroclastic rocks fracture structure with theformation of shallow volcanic type,shallow volcanic hydrothermal copper and goldmine.According to the study area southeast of diorite mineralization characteristics and withmineral diorite porphyry copper deposit and Xinjiang Kara Mr. Siegel the diageneticera,tectonic setting,rock chemical characteristics with similar or the same characteristics,inthe rock mass nearby looking for porphyry copper conditions.
