Geodata Mining And Target Enclosing By Geology Geochemistry & ETM～+ Romote Sense In Alagou Area Tianshan Mountain

The study region locates in the east of Yilianhabierga Mountain and Boluokenu Mountain, which belong to the eastern section of the West Tianshan Mountain. Considered with geotectonic view, it's the combinative region of Kazakhstan-Junggar Plate and Tarim Plate. Bingdaban-Xiarega Fault runs through this area in northwest-west orientation. As a boundary, the north of the fault is Upper Paleozoic arc-basin belt of Yilianhabierga (III level), which is in epicontinental accretion active belt of North Tianshan Mountain in Varisian age (II level), and the south of the fault is Lower Paleozoic island-arc belt of Boluohuoluo, which is in epicontinental accretion active belt of Mid Tianshan Mountain in Caledonian age (II level). This area develops intensive structure activities, so has good geological condition of mineralization.Areal geology survey shows, Bingdaban Ductile Shear Zone contributes to gold ore-forming. It forms the main ore-control structure belt in this area, controlling ore-forming process of Au as well as other metal, and has good ore-prospect. Saridala and Wangfeng gold mine, to the west of the study area, are produced in this ductile shear zone. The study area has the same geo-evolvement process and similar geological structural background to the former, so can be taken as geological target area of kin mines. There are four fracture groups of NWW, NE,EW and approximately SN orientation. We especially pay attention to the development of lateral secondary fractures, slanting across the main structure belt in this area, whose appearance can be one of ore-hunting indicators.Based on the analysis of probability distributing of relative indicator elements to Au ore-forming in Saridala diggings, which is adjacent to the west, we did relative statistical research on gained rock's geochemistry data in study area. We mainly analyzed the abundance and their gathering status of 11 indicator elements of Au, Ag, As, Sb, Bi, Cu, Pb, Zn, Sn, Ni, Mo, seriously reviewed the strata and magma rock's ability of offering the source of ore-forming material, and indicating meaning of relative elements group in ore-hunting field. The evaluating results provide evidence for the set of ore-hunting target,...
