Research On The Metallogenic Regularity And Metallogenic Prediction Of Neogene Sand Conglomerate Type Gold Deposit In The West Of Yunnan Province

West yunnan sanjiang area in eastern Europe and Asia, tethys orogenic belts to turn parts of the south east, is one of the most promising resources enrichment region in western China. The ailaoshan tectonic belt in jinsha river- is origin of the newly emerged large gold deposits in resources and important nonferrous metal and precious metal mineralization belt. Mining gold long history in the region, the research work about the gold in the 1950 s and 80 s has carried out a systematic work, after a number of important research results have been achieved. The results of this study focused on the Paleozoic and Mesozoic jinshajiang ailaoshan structural belt, characteristics of geology and mineral resources research of the structural belt and the surrounding Cenozoic geological characteristics and metallogenic role involves very little. Jinsha river- ailaoshan structural belt is one of the important structural belt and the metallogenic belt of western yunnan. Should you take a number of important copper and gold deposits have been found, which constitute important copper and gold metallogenic belt(Li Dingmou etc., 2002). Tectonic belt and lancang river, nujiang river tectonic belt, ailaoshan tectonic belt in jinsha river-with its unique geological structure, a variety of mineralization and unique humanities, geography, and rich ecological landscape, and pays attention to the Chinese and foreign geologists, become one of research hotspots of the qinghai-tibet plateau.This paper make full use of the research work of dalongtan region in recent years, the basic geological and mineral exploration of new materials, new progress was made, using the related discipline of new knowledge, new technology, new method, to analyzes the dalongtan gold deposit is a typical representative of ore deposits, ore belt formation strata, sedimentary characteristics and sedimentary facies, makes a comprehensive study of geological structure, geochemical background and metallogenic model is established, then the neogene glutenite type gold deposits in western yunnan region mineralization possibility to predict the possibility of the same type gold deposits metallogenic sections.In field investigation, indoor test and analysis, on the basis of comprehensive study, this paper made the following main know: south China gold sand breccia type gold deposit with multiphase(multiple) characteristic of the superposition of mineralization. Dalongtan neogene sedimentary basin has provide the source of source rocks. The ancient placer gold deposits are controlled by strict to layers of a. For the neogene of south China gold mine of ore-bearing bed, the 3rd battalion group. Through to the western yunnan gold provenance, stratigraphic features, sedimentary basin, sedimentary facies and sedimentary microfacies and sedimentary tectonic activity and alteration effect after the analysis of the thought of western yunnan, especially the jinshajiang ailaoshan- neogene tectonic belt adjacent to the region have sand breccia type gold deposits(dalongtan gold metallogenic conditions.
