Discussion On Metallogenic Potential Of Chazi Area In Tibet

The Tibet Chazi area is structurally located on the west side of the Gangdese metallogenic belt,and the northern part is adjacent to the Shierg River-Longge-Songdu-gongbujiangda fault and the Geer-gongbujiangda compound island arc zone.The south side is adjacent to the Yarlung Zangbo River.The combination zone and the Shigatse arc are adjacent to the basin.The structural conditions of the Jammu area are complex,and the evolution process of the multi-island arc lake basin in the Gu-Xin Tethys Ocean has been experienced.The magmatic activity in the area is frequent and corresponding mineralization.This paper is guided by the continental collision metallogenic theory and is characterized by magmatic mineralization.Based on the theory,based on the systematic geological survey of the study area,the ore-forming conditions of the Jammu area were objectively evaluated.The author conducted U-Pb zircon dating for the mineralization-related granites obtained from the regional adjustment work in the Jammu area.The data of major elements,trace elements and rare earth elements were analyzed to clarify the age of mineralization and analyze the diagenesis.The tectonic setting,the Re-Os isotope test of molybdenum ore has proved the source of ore-forming materials,and according to the geochemical anomalies in the study area,the extraction of remote sensing alteration information has been carried out to determine the area of the exploration area.Prospecting sign.These objective experimental data provide strong support for the mineralization potential in the study area.There are more than ten ore points in the study area,and their genetic t ypes are different.Based on the analysis of the genesis of the magmatic rocks in the study area,combined with the characteristics of elemental rich ore,it i s believed that the prospecting direction of the study area should be Molybden um ore is the main component,polymetallic ore.This paper solves the proble ms of metallogenic background,metallogenic age and metallogenic regularity in the Chazi area.
