根据47个C~(14)年代数据,对渤海湾沿岸晚第四纪地层进行了年代划分。以全新世海相地层下伏的泥炭层或淤泥层为标志层,其下为晚更新世地层,其上为全新世地层,年代界限为距今10300年。全新世地层进一步划分为早全新世地层、中全新世地层和晚全新世地层,其年代依次为距今10300—8000年、8000—2500年、2500—现代。 Based on the data from 47 C ~ (14) years, we divide the Late Quaternary stratigraphy of the coast of Bohai Bay. The Holocene marine strata underlying the peat layer or silt layer as a marker layer, which is under Late Pleistocene, which is Holocene over the age limit of 10,300 years ago. The Holocene strata are further divided into Early Holocene strata, Middle Holocene strata and late Holocene strata, with ages 10300-8000, 8000-2500 and 2500-modern.
