摘　　要：韦州矿区太原组含煤岩系中钙质泥岩(灰岩)成分主要为陆源碎屑石英、岩屑和方解石微晶组成,富含有机质和动物化石及碎屑。根据岩石学及古生物化石对其进行综合分析,认为钙质泥岩(灰岩)主要是海湾潟湖沉积。通过分析各层钙质泥岩(灰岩)的时空分布及物性特征,指出在本区太原组沉积厚度大、灰岩不甚发育的情况下,钙质泥岩可作为煤岩层对比可靠的标志层。The components of calcareous mudstone （limestone） in the Taiyuan Formation coal-bearing strata in the Weizhou mine area are mainly terrigenous detrital quartz, debris and calcite microcrystal, rich in organic matter, zoolith and fragments. According to lithological and paleobiological comprehensive analyses, considered that the calcareous mudstone （limestone） is mainly bay lagoon deposit. Analyzed each layer calcareous mudstone （limestone） time-spatial distribution and physical property characteristics, pointed out under the conditions of thick Taiyuan formation deposit and none so developed limestone in the area, the calcareous mudstone can be the reliable marker bed of coal and strata correlation.
