本文以地球化学过程基本定律为指导，根据区域和矿区外围八条剖面169件样品的分析数据，采用柯尔莫各洛夫非参数正态检验法，对黔西南铊矿床（点）赋矿地层中成矿元素Tl、An、Hg、Sb、As、Pb、Zn的丰度值进行了研究。在此基础上，通过簇群分析探讨了各赋矿地层中的元素组合规律；引入后期作用叠加强度系数，对各地层的含矿性进行了评价，指出本区的峨眉山玄武岩组、龙潭组、长兴-大隆组以及夜郎组第一段，不仅是本区键（包括部分重要金汞锑砷）矿床的主要赋矿地层，而且也是这些矿床（点）成矿物质的重要来源。
In this paper, guided by the basic law of geochemical process, according to the analysis data of 169 samples from eight sections in the periphery of the area and the mining area, Kolmogorov nonparametric normal test method is used to analyze the distribution of thallium deposit The abundance values of Tl, An, Hg, Sb, As, Pb and Zn were studied. Based on this, the rule of element combination in various ore-bearing strata was discussed through cluster analysis. By adding the superimposed intensity coefficient of late-stage effect, the ore-bearing of each strata was evaluated. It is pointed out that the Emeishan basalt group, Longtan group, The Changxing-Dalong Formation and the first segment of the Yelang Formation are not only the major ore-forming strata of the key (including some important Au-Hg arsenic arsenic) deposits in this area, but also the important source of the ore-forming materials of these deposits.
