摘要
Soil geochemical measurements at 1:25 000 scale around the Caojiba area of Liangcheng County, Inner Mongolia reveal an anomaly combination of multiple elements dominated by Au accompanied by As, Cu and Ag. This paper used the method of mathematical geology to analyze the data of soil geochemical survey at 1∶25 000 scale in Nanhuofang of this region, and made a geological interpretation to the deposit. It suggests that the anomalies from the geochemical survey are associated with mineralization along a series of NE trending fracture zones. Cluster analysis shows that eight kinds of trace elements can be divided into four categories, i.e. Cu, Ag, Au and As as the first, Pb the second, Zn the third, and Bi and Sb the forth. There are 33 samples of which the factor F1 scores more than 1 among all the 440 samples from the Nanhuofang area.
