摘　　要：因子分析是研究元素共生组合的一种有效方法，其中的每一个因子都表示一种元素之间的组合关系，这种组合关系的研究对于成矿预测有很大的帮助。通过对甘肃省两当县田坝子一带的地球化学数据中的十三种元素进行R型因子分析，得出该区的金矿成因属中低温热液成因；Bi及Cu、As、Sb是该区金矿的重要指标元素，尤其是Bi，与金矿的关系最为密切，可作为直接指示元素。Factor analysis is an effective method to study element association and each factor represent relationship between the elements, which is of great help for metallogenic prediction. Through R-type factor analysis of thirteen kinds of elements in the area of Tianbaizi in Liangdang county, Gansu Province, conclusion is made that gold deposit in that area belongs to moderate-low temperature hydrothermal origin and Bi and Cu, As, Sb are important index of the gold deposit, especially Bi, which is most closely related to the gold deposit thus can be regarded as a direct indicator element.
