摘　　要：石咀山矿区石炭二叠纪煤层中广泛分布着高岭岩夹矸,其层位稳定,矿物岩石学特征独特,是煤层对比的理想标志层。文章阐述了各夹矸的层位和覃度变化、岩石类型和特征、化学成分和矿物学特点,分析了夹矸的成因。Kaoli-nite Partings are widely distributed in Perm(?)-carboniferious coal seams in Shizuishan minearea.Having stable horizon and special minera-logical characteristics,the partings constituteideal key horizons for seam correlation.Thehorizon and thickness change of the differentpartings,petrographic characteristics,chemicalcomposition and mineralogical features are de-scribed,and the genesis of the partings is ana-lysed.
