Characteristics and evaluation of soil geochemical anomalies of the Woergei gold deposit in Gansu Province
摘要
Abstract
Based on 1∶10 000 soil geochemical survey on the Woergei gold deposit in Gansu Province, the authors used the R-model factor analysis method to evaluate geochemical anomalies.Cluster analysis of the soil geochemical data obtained from the Woergei gold deposit shows that eight kinds of elements can be grouped into three categories, i.e.,(1) Sb,As,Au,Pb,Ag;(2) Cu,Zn;(3) Hg.Combined with favorable ore-controlling factors such as lithology and structure,the authors applied the system core theory to synthetic evaluation of main ore-forming elements and the abnormal element combination,and then selected three prospecting target areas.In No.Ⅰ,Ⅱ and Ⅲ anomaly target zones,the systems of nuclear are respectively {Au,Pb},{Au} and {Cu},the system stability is strong,and the abnormal Ⅰ and Ⅱ areas were verified by drilling and pit engineering.The mineralization location,size and element anomaly concentrated heart position are in good agreement in the two abnormal zones,suggesting that soil geochemical survey is effective in the study area.However,No.Ⅲ anomaly target zone has the system of nuclear of {Cu},with the anomaly in the area displaying the main ore-forming elements Cu Au anomalies,the malachite and covellite were found in field investigation, which are relatively consistent with the anomaly target area,and hence drilling and pit engineering in the abnormal area should be conducted.关键词
