Soil Geochemical Characteristics in the Naqu Area,Chongzuo City,Guangxi,and Their Mineral Prospecting Applications
摘要
Abstract
The Naqu area has significant potential for uranium mineralization,and the molybdenum ore found in association with uranium has considerable value for comprehensive utilization.However,there has been a lack of systematic exploration work on the molybdenum occurrence in this area,hampering the regional molyb-denum ore prospecting.To facilitate regional molybdenum ore prospecting,we conducted a 1:10,000 soil geo-chemical survey.In the survey,we systematic collected 3,295 soil samples,which were analyzed for 10 ele-ments,including Au,Ag,As,Bi,Hg,W,Mo,Cu,V,and Ti.Multi-variant analysis indicates that Mo is a significant ore-forming element in the study area.The original data were conducted to R-type cluster analy-sis and R-type factor analysis using the SPSS 22 statistical software.The results yield five ore-forming element assemblages:Ag-Cu-V,Bi-Ti-W,As-Mo,Au,and Hg.The contrast anomaly method was utilized to deter-mine the anomalous lower limit of each individual element and their assemblage.Subsequently,the contrast data of each ore-forming element assemblage were processed with the Geochem Studio 3.5 software,which cre-ated an anomaly map.Basing on the geological conditions,we proposed three potential prospecting targets,which were then delineated for further investigation.Engineering verification was conducted on the No.1 target through trenching and drilling,revealing the presence of an industrial-grade molybdenum deposit with a Mo grade of 0.11％-0.15％(average 0.112％).Verification of trench engineering was performed in the No.2 target,and analysis of sampled trenches indicates the presence of mineralized molybdenum grade.These find-ings point to a substantial molybdenum mineralization potential in the Naqu region.关键词
