塔里木盆地是我国白垩系发育良好的地区之一,兼有海相层、海陆交互相层和陆相层,各门类化石丰富并保存良好。经过各部门数十年的潜心研究,取得了长足进展。本文在总结前人工作并结合自身工作的基础上,分析了塔西南地区和塔北地区白垩系各岩石地层单位的时代划分和归属,对若干重点地层单位的时代和对比做了剖析并将该盆地的白垩系与相邻地区的白垩系做了对比分析,从而初步建立了塔里木盆地白垩系的地层格架和塔西南地区与塔北地区白垩纪各岩石地层单位的时代对比机制。
The Tarim Basin is one of the well-developed Cretaceous areas in China. It has both marine facies, marine-continental interaction facies and terrestrial facies. Each kind of fossils is rich and well-preserved. After decades of painstaking research by various departments, great progress has been made. Based on the summarization of predecessors’ work and combining with their own work, this paper analyzes the division and affiliation of the Cretaceous lithostratigraphic units in the area of southwestern and northern Tarim, analyzes the times and contrasts of some key strata units, The Cretaceous in the basin and the Cretaceous in the adjacent area are compared and analyzed. The Cretaceous stratigraphic framework in the Tarim Basin and the Cretaceous lithostratigraphic units in the area between the southwestern Tarim Basin and the northern Tarim Basin are compared.
