Geological Characteristics And Prospecting Direction Of Huanrenerpengdianzi~kuandianwanbao Molybdenum Polymetallic Deposit

Huanrenerpengdianzi ~ kuandianwanbao molybdenum polymetallic deposit is located in the in kuandian county east 80 ° bearing zhenjiang town area,about 55 km from kuandian county east straight line distance. Geotectonic position is a sino-korean paraplatform Jiaoliao tailong Yingkou kuandian ~ Taiwan arch and taizi river Hun Jiang sets the transition area, east of southern liaodong ancient rift valley center, is a regional Na Fen ~ wanbao precious and nonferrous metal metallogenic belt and the yalu river composite parts of the precious metal metallogenic belt. This study on ore-controlling rock mass in the study area of isotope, rare earth elements and trace elements test and analysis, combined with the mine geological characteristics, metallogenic material source, ore deposit types, ore deposit origin,summarizes the metallogenic regularities, prospecting direction prediction.Research zone porphyry molybdenum ore body occurs in yanshanian granodiorite, granite porphyry and quartz porphyry, or occurrence in yanshan epoch,granodiorite and adamellite granite porphyry contact parts of the alteration belt. Ore bodies are vein of output, and given priority to with concealed ore body. Ore minerals are mainly molybdenite, containing a small amount of pyrite, occasional sphalerite and chalcopyrite. Ore structure is given priority to with pack cementation structure; Ore structure is given priority to with disseminated and vein. Wall rock alteration are mainly silicification, potassium, black mica, silk Yun Yan Huang Tie,chloritization, most close relations with mineralization of silicide, Huang Tie silk Yun Yan.Tectonic altered rock type deposit in the area mainly occurs in the fracture structure. Ore bodies are vein or lenticular output, and given priority to with concealed ore body. Ore minerals are mainly molybdenite and magnetite,chalcopyrite, galena, malachite, containing a small amount of pyrite, occasional sphalerite. The main structure of mineral for cataclastic structure; Ore structure is given priority to with block. Wall rock alteration types are mainly silicification and chloritization, silk Yun Yan Huang Tie, carbonatization, illite hydromica; Among them, silicide, Huang Tie silk Yun Yan, carbonatization and is most closely related to mineralization.In skarn type deposit mainly occur in the yanshan period magma activity into upper Paleozoic carbonate formed by in-situ skarn. Ore bodies are vein output.Ore minerals are mainly magnetite, chalcopyrite, galena, malachite, containing a small amount of pyrite, occasional sphalerite. The main structure of mineral for cataclastic structure; Ore structure is given priority to with block. The main alteration types of surrounding rock for the silicide, hotaru petrochemical and chloritization.; Among them, silicide, hotaru petrochemical and is closely related to mineralization.This thesis will area research mineralization in the area can be roughly divided into three stages: the first stage, the metallogenic period before stage; The second stage, namely the early mineralization stage; The third stage, namely the main metallogenic stage. And from the strata, structure, magmatic rocks, wall rock alteration four aspects discusses the metallogenic control factors. On the basis of the study, summed up the research area of different genesis of deposit prospecting marks.Ultimately determines the second tent Turkey stone- birch Turkey stone copper, lead,zinc, molybdenum, gold prospecting target areas and wanbao peripheral copper,molybdenum, gold prospecting target areas two favorable prospecting direction.
