Geochemistry ore-forming elements association is an important indicator of ore deposit. In this paper, we adopt JADE algorithm based on the theory of independent component analysis to analyze the character of geochemistry mineralized element association, which discussed the combination anomaly from the point of view of Nonlin-earity. It has been applied in Dongga gold deposit point in Tibet and good results were obtained.%地球化学成矿元素组合是指示矿床存在的重要标志,这里尝试基于独立分量分析理论中的JADE算法分析地球化学矿化元素组合特征,从非线性科学的角度来评判元素组合异常,并在西藏洞嘎金矿的科研实践中取得了良好效果.
