Research On The Rock Geochemical Characteristics And Metallogenic Regularity Of Ore-bearing Rock Series Analysis In Heiniudong-Haidigou Ore Section,liwu Cu-Zn Deposit, Sichuan

The study area is located in Jiulong County, Ganzi Tibetan Autonomous Prefecture, SichuanProvince. Heiniudon-haidigou ore section, is located in the Southwest of the Liwu copper ore field.Through the analysis of major elements, the geochemistry of trace elements, rare earthelements,and geological background, we discuss on the material source and metallogenicregularity.This paper studies the metallogenic geological background and geological characteristics ofthe deposit based on the Heiniudon-haidigou ore section where the Liwu copper-zinc deposit. Byprocessing the field analysis, the previous data of field investigation and laboratory geochemicaldata, we get the rock combination of geochemical characteristics of rocks of the study area of theore bearing rock series, and carry on the recovery of metamorphic rock to offer some referenceand gist for the copper prospecting work.The research results obtained mainly includes the following aspects:(1) Through the field observation, old Tong catalog work and indoor analysis and sorting,this paper determines the ore-bearing rock series of Heiniudon-haidigou includes quartzite, schistand plagioclase amphibolite.(2) Multi-spectrum transformation and texture data extraction will be proceeded on the basisof remote sensing images of the study area, combined the geology, geomorphology, soil, DEM andits derived slope data and aspect data to executed decision tree classification, obtained thelandscape data in the study area.(3) On the basis of the geochemical data in the study area,this paper used the analysisfunction of SPSS, achieved the geochemical background values of each element in the study areaand the scope of the geochemical background values, then based on the data, combined with thespatial analysis function of ArcGIS to extract the abnormal distribution of each element.(4) Integrated view, the Heiniudon-haidigou rock series marinesedimentary formation,sedimentary environment and belongs to the coastal shallowmarine. Process and ore bearing rockformation, and mineral preliminary enrichmentprocess. The ore-forming materials are mainlyderived from ore bearing rocks,mineralization features, causes the multi period, the Zhu Chengkuang effect for high temperature heat in Yanshan period metasomatic filling mineralization,ore deposit is controlled by ductile shear and dome structure.
