摘　　要：新疆东天山的白石泉Cu-Ni硫化物矿床一直受到众多构造学家、岩石学家和矿床学家的关注,但是数学地质在此地的研究尚属空白。文中在系统的野外地质调查基础上,进行了系统采样和岩石地球化学分析,应用多元线性回归和逐步回归分析相结合的方法,借助SPSS数学统计软件系统的研究Cu-Ni变量与造岩元素变量的关系,建立Cu-Ni变量与其他变量的回归方程,验证与解释白石泉Cu-Ni硫化物矿床的成因、岩浆来源等问题,对指导找矿勘探有重要作用,对应用数学地质方法有指引作用。Baishiquan Cu-Ni sulfide deposits located in the eastern Tianshan of Xinjiang have attracted the attention of many tectonists, petrologists and ore deposit experts for a long time. However, the mathernatical study of the geology of this area is still lacking. On the basis of geological field survey, we have made systematic sampling and geochemical analyses of the rocks, and systematically studied the relationship between the Cu-Ni variable and the rock-forming element variables by the method of multi-variate linear regression combined with stepwise regression analysis, using SPSS statistical software. We established the variable regression equation of Cu-Ni variable and other variables, tested and explained the causes of the formation of the Cu-Ni sulfide deposit of Baishiquan and the magma source and so on. It is of significance for guiding the ore exploration and the application of mathematical methods to geology.
