摘　　要：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,包括5个组的全部层型剖面在内,是在西天山研究二叠纪地层的经典地区.通过对5条层型剖面全部进行重测,系统采集样品,取得了成果.主要体现在火山喷发旋回研究、生物化石及岩相分析研究,并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.In Nileke region of Xinjiang, Permian strata are widespread and form complete sequences. The contact relations are obvious and all stratotypes of the five formations are found in the region. It is a classic location for the research of Permian strata in west of the Tianshan mountains. The authors re-measured and systematically sampled the five type sections to study the cycle of volcanic eruption, fossils and facies to make dependable criteria for stratigraphic division and correlation of Permian strata in the west Tianshan mountains.
