Using the multifractal method, the authors studied 12 trace elements and, according to curve shapes, recognized two kinds of multifractal patterns. PatternⅠis a simple multifractal pattern with two nonscale areas, and the second tangential line fits well with the curve, with Hg, Mn, Sb, Mo, As, Zn having this pattern. These elements seem to be nonmineralization elements or oreassociated elements. PatternⅡis a highclustering multifractal pattern, and the fitting extent between the second tangential line and the curve is bad, showing obvious deviation. Some elements present rather obvious deviation, reflecting the superimposition of highcontent element points on Pattern I. Sn, Cu, Pb, Ag, W, Bi mainly show this pattern, and these elements all have extremely large local anomalies in this area, in which the main oreforming elements Sn, Cu, Pb, Ag formed ore deposits of various grades.
