摘　　要：阳逻地区是长江中下游沿岸为数不多的高阶地砾石层出露地区之一,作者研究认为,砾石层的形成时代为早更新世,砾石层内部具有明显的二分性,上部砾石层为阳逻组,下部砾石层为半边山组,砾石层均为发源于大别山南坡的古河流冲积物。Yangluo area is one of the rare places exposing high stepped terrace gravel beds along the middle and lower reaches of the Yangtze River. The gravel beds were formed in Early Pleistocene, and are the alluvia of a paleoriver origining from the south slope of Dabie Mountain. The gravel beds can be further divided into two strata which are different from in time and climate environment: one is Yangluo Formation, the other is Banbian Shan Formation .
