摘　　要：梅河盆地是抚顺──密山深大断裂南段的组成部分，是一个典型的断陷型聚煤盆地。根据钻探、测井和粒度分析等资料，对沉积体系和沉积体系域进行了分析，梅河盆地主要沉积体系有冲积扇－扇三角洲沉积体系、湖泊沉积体系和河流－三角洲沉积体系，每一种沉积体系都由一套有规律的沉积组合构成。随着盆地的演化，梅河盆地先后出现了冲积扇－辫状河、冲积扇－扇三角洲－湖泊、河流－三角洲一湖泊等沉积体系域。eihe basin is the constitution southern sector of the great Fushun-Mishan deep fault. It is a typical coal-accumulating fault basim. The depositional systems and depositional system tracts are studied with real core,logging and grain size analysis etc. The main depositional systems are alluvial fan-fan-delta depositional system,lacustrine depositional system and fluvial-delta depositional system. Every depositional system consists of a serial sedimentary units. The alluvial fan-braided stream dapositional system tract,the alluvial fan-fan-detal-lacustrine depositional system tract and fluvial-detal-lacustrine depositional system tract are occurred in different evolutionary stage of basin.
