This work uses the R-type factor analysis for analyzing the date of 1:10000 soil geochemical survey in the Xieyonggui area. Factor analysis on the soil geochemical data of the Xieyonggui area shows that trace elements here can be divided into three groups, i.e. Cu-Ag-Au-As-Mo, Pb-Zn-Bi-Hg, and Sb. The first group is element association of low-temperature mineralization, the second group is element association of medium temperature mineralization. This paper uses trend surface analysis of factor score to delineating 4 anomalies I, II, III and IV in the Xieyonggui area.
