摘　　要：在尼勒克地区二叠纪地层分布面积最广,地层出露齐全,接触关系清楚,全部五个组的层型剖面均在该区内,是西天山研究二叠纪地层的经典地区。作者对五条层型剖面全部进行了重测,系统采集样品,取得了一批成果。主要体现在火山喷发旋回研究、生物化石及岩相分析研究,从而进行较详细的地层划分,为西天山二叠纪地层划分与对比提供了可靠依据。Permian strata are widely spread with complete sequences and obvious contact relations in Nileke region. It is a typical region for researching Permian strata in west of the Tianshan mountains. Based on analyses of remeasured the five type sections and colleetion of the samples,authors obtained results in researching cycle of volcanic eruption, fossils,facies analysis, and making the detailed stratigraphic division, providing reliable evidences for stratigraphic division and correlation of Permian strata in west of the Tianshan mountains.
