随着非线性科学的发展，成矿作用的分形研究越来越受地质学家的重视。因此，对于地球化学异常，采取了分形方法来确定元素地球化学异常下限及元素异常组合。共选取了胶东矿集区的8种有用异常元素（Au、Ag、As、Cu、Pb、Zn、Hg和Sb）进行分析，对于异常下限分析，采用了分形求和法得出其下限分别为（2.40，47.6，4.75，17.48，24.89，56.50，25.84，0.33）×10-6，其值与胶东矿集区相关资料的吻合程度比较理想。对于元素异常组合，采用了多重分析分形方法，并且运用传统经典的分析方法——R型因子分析进行了对比验证，表明分形方法，作为非线性数学的一种应用，成功地对矿集区元素异常进行了异常下限的确定、异常组合的选择。

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 geochemical 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.
