内蒙古甲乌拉铅锌银矿床3号矿体元素分带规律及深部成矿预测OA

The Jiawula lead-zinc-silver deposit is an important epithermal deposit in Inner Mongolia,with its No.3 orebody being one of the main orebodies.However,research on its element zoning and the spatial variation in true thickness of the orebody remains relatively weak.Based on exploration and production sample data of Orebody No.3,combined with the structural geological characteristics of the mining area,we plotted longitudinal projection contour maps of the main ore-forming elements(Cu,Pb,Zn,Ag)and orebody thickness,and investigated the spatial zoning of ore-forming elements,as well as the variation trend and spatial distribution of orebody thickness.The results indicate that Orebody No.3 displays distinct vertical zoning of ore-forming elements,with Cu,Pb,Zn,and Ag predominating in the upper part,while Cu,Pb,and Ag are dominant at depth,approaching the porphyry body.Along strike,orebody thickness and grade generally correlate positively.Two target areas with favorable deep metallogenic potential have been identified:the Cu domain below the-328 m elevation level between exploration lines 118 and 124,and the Pb-Zn-Ag domain below the-328 m elevation level between exploration lines 76 and 94.These findings provide a scientific basis for deep exploration planning at the mine.
