新疆伊犁盆地地层划分与对比

Stratigraphic Classification and Correlation in Yili Basin, Xinjiang

通过野外实际观察和实测剖面，结合实钻资料化验分析结果，并依据前人工作的基础，对新疆伊犁盆地的实际地层情况进行系统对比和分析，统一了多年来比较混乱的地层单位和名称，建立了伊犁地区标准地层剖面，特别是对下三叠统的巴斯干尔组和上白垩统的东沟组提出了新的更为确切的划分依据，为今后新疆伊犁地区开展其它各项工作提供了基础资料。

Based on field survey and measured section, and combined with data from drilling and lab analysis, this paper provides a systematic stratigraphic correlation and the analysis to Yili Basin, Xinjiang, unifies the stratigraphic units and names which have been in a confusion in the past, and establishes a standard stratigraphic section in Yili Region. The special achievements of this article lies in its new and more accurate basis provided for the classification of Basgar Formation of Lower Triassic and Donggou Formation of Upper Cretaceous,thus laying the foundation for other works in Yili Basin.
