中文摘要：

通过对库拜煤田阿艾村和音西煤矿侏罗系煤系地层观察、实测露头岩性、沉积构造、特征标志、关键界面等方法,划分沉积亚相、沉积相,按垂向组合特征划分体系域单元。在下侏罗统塔里奇克组至中侏罗统克孜勒努尔组划分出5个沉积层序,从中寻找煤层发育有利层位,总结聚煤规律性。对最大水泛面作为沉积层序关键参照界面依据进行讨论。

英文摘要：

Based on Jurassic coal-bearing strata outcrops of Aai Village and Yinxi Coalmine in Kuqa-Bai Coalfield,this paper divides outcrop strata from Low Jurassic Taliqike Formation（J1t） to Middle Jurassic Kezlenuer Formation into five depositional sequences,and find favorable horizon of coal development,summed up coal accumulating regularity.This paper also discusses in aspect of maximum flooding surface as key proof diagnosing depositional sequence.
