| 摘 要： | 根据地面剖面的构造、地层、岩性、古生物等资料，对塔里木盆地库鲁克塔格地区中、下奥陶统的岩石组合特征、化石带分布的分析对比，重新认识了中、下奥陶统的接触关系，认为库鲁克塔格地区南、北相区中、下奥陶统之间存在着地层和化石带的缺失现象，而且区域性的不整合接触关系十分明显。这对于解决盆地覆盖区地层和地震统层具有重要指导意义

| Abstract: | Based on structural, stratigraphic, lithologic and paleontologic data in surface
sections, this paper analyzed lithologic combination characteristics and fossil belt distribution
in Middle and Lower Ordovician in Kuluktag area of Tarim basin, and reconsidered the contact
relation between Middle and Lower Ordovician. It is believed that there is absence of formations
and fossil belts between them and obvious regional unconformity. This may guide stratigraphic
classification in cover area of Tarim basin. |
