Geological Characteristics and Prospecting Potential of Huobulin Pb-Zn-Ag Polymetallic Deposit in Inner Mongolia
Huobulinchagan Pb-Zn-Ag polymetallic ore deposit is located in the east of East Ujumuqin Banner,Inner Mongolia.The structure belongs to the middle part of Xingmeng orogenic belt and west side of the Great Xing'an Mountains metallogenic belt.In order to study the background of mineralization and exploration potential in the mining area,by means of 1∶10 000 geological survey,soil geochemical survey,IP survey,trench engineering and drilling engineering,the regional metal-logenic geological background,geological characteristics of the mining are analyzed and deposit genesis of the mining area are studied comprehensively.The study results show that:① Huobulinchagan Pb-Zn-Ag Polymetallic ore deposit is structural hy-drothermal lead-zinc deposit and the host strata of Huobulinchagan Pb-Zn-Ag Polymetallic ore deposit are Jura Manitu Group and the Cretaceous Baiyigaolao Group.② The mineralized zone is hosted in the northwest faults F1 and F3,with 8 mineralized bodies in S1 and 2 mineralized bodies in S2.These mineralized bodies are approximately parallel to each other and in the form of vein in space.③ The ore consists of sphalerite and galenawith various types of ore texture and structure.④ The relationship between the mineral deposit and geophysical and geochemical anomalies is close,and the centers of concentration of lead,zinc and silver elements within the metallogenic range are often obvious with middle and inner zones of anomalies.The IP shows high polarizability and low resistivity characteristics.Based on the discussion results,combing with the geological characteristics and geophysical characteristics of the mining area and prospecting criteria of the area,the prospecting model of sedimentary i-ron deposit is established,four prospecting target areas are delineated,the further discussion results indicated that prospecting potential of the target areas are good.In summary,the discovery of this deposit fills the gap in metal deposits in the area from Mandubolixilai to Hongqichun,which fully demonstrates that there is great potential for mineral exploration in the area east of the Chaobuleng West-Wulagai fault(F5).
