摘　　要：对分布于金岭寺-羊山盆地与阜新-义县盆地义县组底部陆家屯层、老公沟层沉积环境的粒度分析与对比,不仅揭示了两个盆地初始期冲积扇-河流相沉积环境,而且表明这两个沉积层可以进行对比.由于受到火山作用的影响,两个沉积层体现出粒度分析结果的不完全一致性.Grain size analysis and correlation of the sedimentary environment are carried out on Lujiatun bed and Laogonggou bed at the bottom of Yixian formation in the Jinlingshi-Yangshan basin and Fuxin-Yixian basin, Western Liaoning Province. The results not only reveal a sedimentary environment of alluvial-fluvial facies in the early stage of the two basins, but also confirm the comparability between the two beds. Due to the influence of volcanism, there lie differences in the results of the grain size analysis.
