西藏色林错-它日错地区地层对比清理

Stratigraphic Correlation in the Siling Co-Tari Co Region,Tibet

通过收集、分析前人大量的实测剖面资料,以岩石地层为基础、生物地层为依据,对西藏色林错-它日错地区地层单元进行对比清理研究,认为1/25万区调报告中所建立的下奥陶统拉塞组应归为柯尔多组,三叠系多布日组应归为确哈拉群,并将区内白垩系重新厘定、划分为下统去申拉组、则弄组、多尼组、郎山组,上统竟柱山组,废弃了一批地层单元,统一了该区地层划分对比。

This paper makes stratigraphic correlation in the Siling Co-Tari Co Region,Tibet based on a great amount of measured sections which indicates that the Lower Ordovician Lase Formation in the 1：250,000 regional geological survey report should belong to the Keerduo Formation,the Triassic Duoburi Formation should be divided into the Quehala Froup,and divides the Cretaceous into the Lower Cretaceous Shenla,Zenong,Duoni and Langshan Formations and Upper Cretaceous Jingshan Formation.
