摘要/Abstract

摘要： 本文根据滦河三角洲地区野外调查和25个样品的C¹⁴年代测定结果,讨论了第四纪地层划分和对比以及近代构造运动。研究表明,滦河内迭三级冲积扇的形成年代分别为距今18000年前,11000年前和6000—3000年之间。在全新世中期,渤海湾北岸发生过海侵。三条古海岸线的年代分别为距今5500年、3700年和350年。本区地面下沉最大幅度为10米左右（姜各庄）。由于滦河最新三角洲的西部和东部地壳下沉速度不同,使滦河河道自全新世中期以来不断向东移动。

Abstract: Based on the field investigations and C14 datings of 25 specimens, the problems about the division and correlation of the Late Quaternary stratigraphy and the recent tectonic movement in the region of the Luanhe River Delta were discussed.The studies indicate that the three incised alluvial fans of the Luanhe River were formed during about 18000, 11000 and 6000-3000yrs. B P, respectively. In the northern coast of the Bohai Bay, there was a transgression during the Middle Holocene. The ages of three ancient coastlines are of about 5500, 3700 and 350yrs. respectively. The largest subsidence amplitude is of about 10m(Jianggezhuang). Owing to the difference of the east and west parts of newest delta of Luanhe River in subsidence rate,the course of the Luanhe River was continuously migrating eastward since the Middle Holocene.
