Multi-Metal Geochemical Characteristics Of Au?Sb And Metallogenic Prediction Of The Najiaba In Li County, Gansu Province

The geochemical data processing method is one of the research priorities in the geochemical prospecting and prospecting work.In this paper,different geochemical treatment methods are analyzed and compared,and the method of delineating the lower limit of different elements in the region is put forward.The research results are of great significance Distribution characteristics,to guide the prospecting is of great significance.Based on the geochemical and geochemical characteristics of the ditch system in the Lijiaba area of Li County,Gansu Province,the geological and environmental characteristics of the area were analyzed by using the traditional statistical methods,CA fractal method,correlation analysis,factor analysis and cluster analysis.The contents of Au,Ag,Cu,Pb,Zn,As,Sb,Hg,Bi,Mo and other elements in the samples were analyzed.The distribution characteristics of the elements and the symbiotic combination were investigated.Figure,to determine the favorable elements of mineralization and its mineralization prediction,this paper draws the following conclusions:Cu,As,Sb and Hg in the stratum are relatively uniform.The anomalous effect of the elements is better than that of the CA method.The distribution characteristics of Au,Ag,Pb and Bi are obviously affected by the local structure,CA method is used to delineate the abnormal effect of the element CA method is better than the traditional statistics,verify the complex geological structure in the geological structure,CA method for the lower limit of the effect is better,it can better meet the geological space characteristics;the use of correlation analysis,Analysis and clustering analysis of the three kinds of multivariate statistical methods of 10 kinds of elements were combined analysis,to determine the Cu-Pb-Zn-Bi-Mo,Au-Ag,As-Sb-Hg three groups of symbiotic combination,The results show that Au,As,Sb and Hg are the favorable elements for the study,and the Au,Sb,and Hg are the elements of the study.Two kinds of elements for ore-forming prediction,circle ?,?,?,? four favorable areas of mineralization,to predict ?,? metallogenic favorable area has a greaterpossibility of ore-forming,and ?,? mineralization favorable land Mineralization possible Sex is relatively small.
