with the development of non-linear science, metallogeny fractal have already been a hot point in geology and deposit metallogeny search. So the dissertation probe the possibility of confirm element geo-chemical anomaly’s the lower limit value and analyse element geochemical anomaly combination. In Jiaodong peninsula, we choose eight element (Au、Ag、As、Cu、Pb、Zn、Hg and Sb). As to the lower limit value, we choose the method of summation in fractal model, the result shows the value respectively is (2.40,47.6,4.75,17.48,24.89,56.50,25.84,0.33)×10-6, which is conform to co-relational material and data; as to the geo-chemical anomaly combination, we choose the method of multi-fractal model in fractal theory, in order to prove the veracity of the method, we analysis on these elements by R type factor-analysis.The result shows the non-linear method is reasonability in analyzing element geo-chemical anomaly.
