Tibet Law Firm Region When The Picture Is Located In The Southeast Of Tethys Himalayan Plate

Tibet law firm region is located in the southeast of tethys Himalayan plate, which belongs to the great Himalayan metallogenic belt in the north Himalayan metallogenic belt. The belt is mainly a zarathustra, wave mazar-e-sharif, clamp gold deposits, such as car poor zhuo cloth, salad bar, yong, antimony deposit, known as "south Tibet polymetallic metallogenic belt”. Restricted by the natural conditions and traffic inconvenience, there's few geological exploration nor comprehensive research data. As authorized by the Tibet jiangnan mining co., LTD., our team took on the periphery prospecting work and carried out the Tibet mineral vision son los pierced lung area survey projects. I was responsible for the implementation of project and fully involved in the project, through which I obtained reliable data to finish this thesis.Based on the predecessors' research, we compiled regional geologic data,,drawed the 1:50000 stream sediment survey, conducted in the studied area; With 1:50000 stream sediment test data as the foundation of work, through the analysis of the probability distribution method element data structure is in line with the normal distribution characteristics, through the concentration coefficient, variation coefficient analysis element data structure characteristics; By type R cluster analysis method to determine the prospecting indicator elements combination in the study area:(1)Pb-Zn-Ag?(2)As-Sb-Au-Hg?(3)W-Sn-Bi-Mo; By abnormal iteration method to determine the background value of 16 kinds of element data in the study area and the threshold, and use the data as a catchment units geochemical anomaly data of three concentration zoning, preparation of single element anomalies, combination element geochemical map and comprehensive.Through the analysis of the metallogenic geological background, metallogenic conditions, system construction, strata, magmatic rocks in the study area, the same geological conditions of the known mines the information such as the main ore-forming elements; With abnormal generally larger scale, strong heart clear, level 3 zoning phenomenon is prominent, and to delineate favourable areas for indicating significance to trace and delineating metallogenic target coupling elements; Found that Pb in the study area, zinc, Ag, Sb, W, Sn, Bi elements such as abnormalities are demonstrated in northern sheet is very good, and more comprehensive performance for three kinds of elements in accordance with the regional metallogenic conditions, think for prospecting have stronger instructions, and delineated the chapter, heat to the top two prospecting area.
