The research by participating in mineral resource potential assessment project in Tibet,On the basis of collection of areal survey information and scientific research,establishing the data map and the structural map of Qamdo.In the process of maping,determining the stratigraphic system of the structural map,determining the rock stratigraphic units and rock assemblage of rock stratigraphic units.Based on the comprehensive analysis of existing data of formation, Integrated the rock association unit in Qamdo area, t he conflation rock association unit to the formation of combination type,Categorized the sedimentary formation by the lithostratigraphic units,And analysis of the depositional environment, Through regional comparison and petrochemistry,Geochemical analysis, Geochemical analysis,determining the type of intrusive rocks which in different geologic eras,summing up tectonic fabrics and geotectonic unit of intrusive rocks,filling out the Layer data form in Qamdo of Tibet,and it will be benefit to geological research in this area,it provided a good background information for future similar projects and Geological Database building.Select A typical deposit,And analyzed:Tibet Yulong Copper (Molybdenum) deposit,the largest of China Sanjiang porphyry copper deposit,It located in the Sanjiang Tethys tectonic belt in eastern,Complex tectonic framework,It Belongs to the Yulong porphyry copper (molybdenum) ore belt,and it not only is an important copper metallogenic zone,but also one of the most abundant copper resources in China,Therefore we chose the Yulong porphyry copper (molybdenum) deposit,as a typical deposit,This thesis based on the accumulated knowledge in The processes of mapping,following the principle of combining field investigations with indoor synthetic analysis Focus on carrying out geological investigate and research in Tibet Yulong Copper (Molybdenum) deposit, metallogenic geological background and the deposit features are discussed aiming at this typical deposit ,rock stratigraphic units,r ock association,local structure,structural setting,minerogenetic epoch,wall rock alteration,mineralogical composition,the shape of metal ore,The occurrence of ore body and other factors were analyzed in classification statistically.sums up the mineralization Elements of this typical deposit.typical mineral deposits forming essential factors is further divided into two aspects:geological environment of regional metallogenesis,r egional geologic feature,And the ultimate regional forecast elements are summarized and converted with region. The geological conditions and the ore-prospecting indicators are determined.metallogenic model of ore deposits and regional metallogenic model are established. based on the structural map of Qamdo, determinating and Extracting prediction elements. combining the Structural outline map,elementary anomaly map and placer mineral anomalies map in this area,based on several prediction elements superimposition. Finally, three far-seeing zones of geothermal exploration are submitted in this area: 1.JiaJiaDong prospecting areas for Cu,P b,Z n,Au,A g ; 2.Yulong-Duoxiasongduo prospecting areas for Cu,Mo,A u,Ag; 3.Xiariduo prospecting areas for Cu,M o,A g. Among them,JiaJiaDong prospecting areas located on the Bagong horst axis that in in southwestern Tuoba. nearly parrallel to the Yulong copper Belt.have good prospecting potential.after a geological survey around Yulong copper deposit. re-cogitating Wenquan fault that closely tied with Copper Belt, Wenquan fault should be separated in to two different periods. A west dipping and normal-strike-slip fault in the Mesozoic; Because of the continuing collision between India and Asia during Himalaya epoch, Wenquan fault changed into thrust nappe fault. as a result, Yulong Porphyry is widely developed in Himalaya epoch,...
