Study On Guarantee Degree And Exploration Layout Of Pb Zn Mineral Resources In Yunnan Province

Mineral resources are important metal materials for the development of national economy.Yunnan Province is a large non-ferrous metal Province,in which lead-zinc mines account for a large proportion.With the continuous development of social industry and agriculture,the demand for lead-zinc mines is growing,and the contradiction between supply and demand is increasingly prominent.Therefore,in order to alleviate the bottleneck problem of economic development,it is necessary to strengthen the research on the guarantee degree of lead-zinc mineral resources in Yunnan Province,and carry out exploration and layout in areas with good metallogenic conditions.The lead-zinc mineral resources in Yunnan Province are large in scale,which are generally distributed in Qiaojia,Ludian,Yiliang and Huize in Northeast Yunnan Province,Lanping,Tengchong,Baoshan in West Yunnan Province,Lancang and Luziyuan in Southwest Yunnan Province,Wenshan and Mengzi in Southeast Yunnan Province,etc.At present,80% of the lead-zinc deposits found in Yunnan Province are concentrated in the above mineral deposits.Based on a large number of data collection,this paper systematically expounds the metallogenic geological background,metallogenic conditions,metallogenic regularity,regional metallogenic elements and metallogenic model of the main lead-zinc mining areas in Yunnan Province.At the same time,it summarizes the distribution of lead-zinc mineral resources in Yunnan Province,and makes a statistical analysis on the amount of lead-zinc resources.The types of lead-zinc mineral resources in Yunnan Province are classified,including Huize and Maoping carbonate type lead-zinc deposits in Northeast Yunnan,Lanping glutenite type lead-zinc deposits in western Yunnan,Lancang marine volcanic rock type lead-zinc deposits in Southwest Yunnan,Luziyuan skarn type lead-zinc deposits,Dulong skarn type lead-zinc deposits in Southeast Yunnan,and other types of lead-zinc deposits.The prospect of lead-zinc resources in Yunnan Province is relatively good.The static security period of lead ore is less than 5 years,the dynamic security degree is 10-20 years,the static security period of zinc mine is less than 5 years,and the dynamic security degree is 5-15 years.The main lead-zinc mineral exploration areas in Yunnan Province are: 1)carbonate type lead-zinc deposits and their surrounding areas in Huize and Maoping,Northeast Yunnan;2)sandy conglomerate type lead-zinc deposits in Lanping,Western Yunnan;3)skarn type lead-zinc deposits in Tengchong area,Western Yunnan;4)skarn and carbonate type lead-zinc deposits in Baoshan and surrounding areas of Western Yunnan;5)magmatic lead-zinc deposits related to magmatism in Luziyuan banlao area,Southwest Yunnan;6)Lancang marine volcanic rock type lead-zinc deposit and its periphery in Southwest Yunnan;7)Dulong skarn type lead-zinc deposit and its periphery in Southeast Yunnan.It has a certain guiding significance for the exploration and distribution of lead-zinc mineral resources in Yunnan Province.
