一、前言 河北省第四系的海相层,过去只在盐山、黄骅、宁河、天津等渤海沿岸地区有所发现。近年来,随着我国地质工作的迅速发展,相继在冀中的献县、河间县、文安县、雄县、霸县一带以东共26个市县的广大地区都有发现。由于其分布广、层位稳定、化石丰宫,因此对它的研究,对于河北省和我国沿海地区第四纪地层的划分和对比,及其与此有关的第四纪海水进退规律与新构造运动的性质等问题,都有一定意义。
I. Preface The marine facies of the Quaternary in Hebei Province were found only in the areas along the Bohai Sea, such as Yanshan, Huanghua, Ninghe and Tianjin. In recent years, along with the rapid development of geological work in our country, one after another has been found in vast areas in 26 counties and cities in the east of Xian County, Hejian County, Wen’an County, Xiong County and Baxian County in Jizhong. Due to its wide distribution, stable strata and fossil abundance, the study on it is of great significance for the division and comparison of Quaternary stratigraphy between Hebei Province and the coastal areas in China, and its related Quaternary seawater advance and retreat laws and structures The nature of sports and other issues, have a certain significance.
