摘要(Abstract)：

本文对鄂尔多斯盆地桃112井和陕473井的北庵庄组和马家沟组开展详细的牙形石分类学和生物地层学研究,共采集90件碳酸盐岩岩心样品,经处理后在35件样品中获得353枚牙形石。所获牙形石可归入10属12种,以暖水类型为主,表现出强烈的地方特征,同时也见到少量广布类型牙形石。在所采井段层位可识别出3个牙形石生物带,自下而上分别是Histiodellaholodentata-Tangshanodustangshanensis带、Aurilobodusaurilobus带、Plectodina onychodonta带,时代为中奥陶世达瑞威尔期中期。该牙形石带序列可与河北唐山、山东莱芜、河南巩县及安阳的同期序列进行直接对比,也可与新疆塔里木盆地和北美中大陆区相当层位进行良好对比,此外还可与华南的同期化石带建立对比关系。本文的材料丰富了华北地区奥陶纪牙形石动物群的组成,深化了其与国内外同期典型牙形石动物群及化石带序列的对比,但精细的洲际对比尚需开展进一步工作,今后尤其需要关注的是来自台地和台缘交界处的钻井剖面的化石材料。
