摘要: 位于河北平原东部的河北省大城县、文安县, 霸县、安次县、永清县及固安县(统称廊坊地区南部), 东接天津地区, 东南与沧州地区相毗连, 距渤海湾西岸100多km(图I)。该区第四系发育, 厚度可达400-500m, 夹有数层海相、海陆过渡相层。近年来一些单位对这套地层进行了广泛地研究, 并取得了一些成果。, 一般倾向认为自晚更新世以来发育了三个海相或海陆过渡相地层, 发生过三次海侵。

Abstract: Some scientific research units concerned have published several theses and have adiscussion on the problem how many marine transanressions have occurred to the wes-tern coast of the Bohai Gulf since Late Pleistocene. It is generally held that there werethree or four marine beds in this area as deposits resulting from the three marine tran-sgreisons.
