摘要
以概率密度统计分析法研究滇东黔西晚二叠世煤层中伴生元素的成因分布类型,表明同一煤层不同元素及不同煤层同一元素具有不同的成因分布类型。各元素的成因分布类型又表明,该区煤层均受到过成岩后生变化和岩浆热液作用影响。
From the angle of statistical analysis ofprobability density,the genetic distributiontypes of associated elements in Late Permiancoal seams in eastern Yunnan Province andwestern Guizhou Province,southwestern China,were studied in this paper.It was indicatedthat different elements in the same coal seamand the same element in different coal seamspossess different genetic distribution types.Thegenetic distribution types of various elementsshowed that coal seams in the research areawere more or less influenced by diagenetic andepigenetic changes and by the action of hotmagmatic solution.And,the content and itsvariability of As,S,and Fe in coal mightserve as the indicator of the intensity of dia-genetic and epigenetic reformation and of hotmagmatic solution action on coal seams.Moreover,it was suggested that the hot magmaticsolution in the area is characterized by lackof Ge,Ga,U,and Th and rich in As,S,and Fe etc.
