摘要： 英买力地区构造隆起发育,综合利用英买力地区白垩系的各种资料并结合区域古地貌,识别出本区发育的冲积扇相、扇三角洲相、湖泊相和正常三角洲相等4种沉积相类型,并详细分析研究了每种沉积相的岩性特征、沉积构造和沉积相的垂向演化序列。地层划分中研究区内是否存在亚格列木组地层是有争议的,本文认为,原划分到侏罗系的一套砂砾岩地层从地层接触关系来看应该属于白垩系的底砂砾岩段即亚格列木组。说明了英买力地区白垩系的沉积沉降中心的多次迁移是造成沉积物和沉积砂体大规模变化和迁移的主要原因。

Abstract: The structural uplift is developed in Yinmaili area. According to available data of Cretaceous and the regional ancient relief in Yinmaili area, four types of sedimentary facies are identified, which include the alluvial facies, fan-delta facies, lacustrine facies and delta facies. Their lithologic features, sedimentary structures and vertical evolution sequences are analyzed in detail. For questionable existence of Yageliemu formation in this studied area, this paper indicates that original classification about the glutenite stratum into Jurassic should belong to bottom glutenite member (i.e. Yageliemu formation) by the strata contact relations. This means that in Yinmaili area the center of sedimentation and subsidence underwent multi-transportation, which is the important reason for the fact that large-scale variation and migration of sediments or sedimentary sand bodies occurred in this area.

Key words: Tarim basin, Yinmaili area, Cretaceous, stratum, sedimentary facies
