摘要
In order to the study the combination of elements in soil thermomagnetic survey,the factor and cluster analyses are applied to research the fourteen elements in zhunsujihua test area.Based on the correlation among the elements of the combined variables and factor scores,the factor score maps are used to indicate the division and determination of the geochemical comprehensive anomaly,which make senses to the ore-body instruction.The results demonstrate that the elements can be divided into three groups,including F1(Cu-Mo-Ag-W-Bi-Te)、F2(Pb-Sb-As-Mn-Fe)and F3(Zn-In-Cd),which provides more useful evidence to soil thermomagnetic survey in strengthening weak mineralization information and distinguishing effective anomaly,moreover,the location of F1 combination has favorable corresponding relationship to the ore-body,and F2 makes further demonstration in explaining the enrichment of mineralization elements in soil thermomagnetic components.
