| The Bajiazi polymetallic ore deposit is located in the northern part of North China platform, Yanliao subsidence zone in the north east part, Shanhaiguan platform arch of the northern margin, located in Wuzhishan- Rainbow Luoshan magmatic rock belt of Nancy. Stratigraphic exposed than the whole, mainly in the Middle Proterozoic, partial disclosure, the Lower Proterozoic and Mesozoic, which were higher than Zhuang group is widely distributed in the region and the main ore beds. The tectonic development in the region, especially the fault structure, is the main ore hosting structure in the mining area. The volcanic and magmatic activities in the area are strong, and the ore-forming geological conditions are favorable. And height of the polymetallic deposit research level and cognitive level, can directly affect the polymetallic mineral ores found reserves and the reserves, in order to increase existing minerals retain reserves and mining area periphery prospecting, the need of Bajiazi polymetallic ore deposit research, in order to meet the needs of industrial production.The purpose of the geological conditions, geological characteristics, ore controlling factors are comprehensively studied, on the basis of changes in regional characteristics of ore deposit types and mineralization elements, mineral composition, chemical composition, mineral structure and elements in space, summarizes the metallogenic characteristics of polymetallic ore deposit, and to determine its magma hydrothermal genesis through the geochemical study of elements, sulfur in typical ore deposits of lead and oxygen isotope characteristics of main elements and metal sulfide, and then use the ore district type and prospecting model of magmatic hydrothermal metallogenic series of ore prospecting theory guidance, increase the existing mineral resources reserves and the increase of ore minerals, in order to expand the ore prospecting.Through the summary and study the geologic characteristics, the analysis on the genesis of ore deposits and determine the draw in bajiazi Mo Pb Zn(Ag) polymetallic ore deposit is magmatic hydrothermal type polymetallic deposit, has the characteristics of typical magmatic hydrothermal type elements divided ore zone and zoning. It perfect magmatic hydrothermal mineralization series theory. |
