摘　　要：豫西济源盆地下侏罗统鞍腰组记录了一套发育于拉分盆地的湖相浊流沉积体系,其中丰富的物理成因沉积构造与生物成因沉积构造以及浊流沉积序列———鲍玛序列都有其自身的特点.沉积环境分析表明,该组地层系湖泊浊积扇不同相带反复沉积的产物.The Lower Jurassic Anyao Formation in Jiyuan basin, western Henan province, central China, records turbidite sedimentation within a lacustrine turbidite system developed in a pull-apart basin. The primary sedimentary structures and stratification sequences have their private characteristics. Facies analysis suggests that this succession is formed in different sub-facies of turbidite sedimentary facies.
