The Analysis Of Geochemical Characteristics And Prospecting Potential In Adaga Area In Xilinguole League,Inner Mongolia

The study area is located in the first tectonic unit belongs to the North China plate,the second tectonic unit belongs to the North China plate continental margin accretion zone,the third tectonic unit belongs to Xianghuangqi-Chifeng volcanic passive continental margin.Based on the field geological survey data and indoor research results,the study area is divided into two four-level tectonic units,namely,the passive continental margin of volcanic type of Wenduermiao Group and the passive continental margin of Chaganhure-Zhaminnuoer volcanic type.The metallogenic belt of the study area is located in the Paleo Asian metallogenic domain(Ejina Banner),Proterozoic Variscan,Yanshanian copper,lead-zinc,gold,silver,chromium,niobium metallogenic area(2),Uligi-Xilinhot Proterozoic,Var.It covers three grade metallogenic belts,including Wenduermiao-Honggerminal iron metallogenic belt(72),Bainaimiao-Hadamiao copper,gold and fluorite metallogenic belt(75),Maoduzi-Moyihada tungsten-fluorite metallogenic belt(77).According to the structure,magmatic activity,sedimentary formation,known deposits,mineral spots,distribution of mineralized points and geochemical anomalies,the study area is further divided into three grade metallogenic subzones,namely,the adaga subzone of iron and gold mineralization(72),the Durenwuliji-Bayandelige subzone.Based on the project of "1:50,000 regional mineral geological survey" in Xilinguole League of Inner Mongolia Autonomous Region,this paper analyzes and summarizes the regional geochemical characteristics by collecting data,and through 1:50,000 soil survey.The data of soil geochemical elements in the study area were obtained,and 76 comprehensive anomalies were delineated.After sequencing and classification,1 class a 2 anomaly,7 class B 2 anomaly,4 class B 3 anomaly and 62 class C anomaly were identified.There are 2 class D anomalies.Eight ore-induced anomalies were identified as AP36 A 2,AP19 B 2,AP20 B 2,AP32 B 2,AP43 B 2,AP47 B 2,AP54 B 2 and AP66 B 2;Through anomaly verification,8 new metal ore(chemical)points,including 5 gold ore(chemical)points,2 lead-zinc ore points and 1 copper-molybdenum mineralization point,were discovered.17 Au mineralized bodies and 5 Au orebodies were delineated by trench exploration engineering.There are 4 Pb Zn mineralized bodies and 4 Pb Zn orebodies,and 1 newly discovered non-metallic ore point is limestone ore point.It provides the prospecting direction for further mineral exploration,summarizes the prospecting criteria in the area,and establishes the prospecting model.One A metallogenic prospective area,one B metallogenic prospective area,one C metallogenic prospective area,three A prospecting target areas,three B prospecting target areas and one C prospecting target area are divided in the area,which provide valuable basis for the next mineral investigation.
