| 摘 要： | 在岩芯观察的基础上,通过对钻井沉积环境的分析,结合其岩性剖面和沉积构造等资料,详细分析了天津地区黄骅坳陷全新世的沉积环境特征、类型及其展布;认为该区主要有冲积、湖沼沉积、河口湾沉积、滨浅海沉积等4种主要沉积环境。全新世为一套松散堆积层,其岩性组合和生物化石组合特征及其变化,反映了天津地区黄骅坳陷全新世以来沉积环境由滨海—近岸浅海至河口湾、潟湖、滨海平原再至冲积平原的演变。

| Abstract: | On the basis of a large volume of geological data from drill core observation and sedimentary analysis,the types,features and spatial distribution of the sedimentary environment of the Holocene in the Huanghua Depression of Tianjin area are analyzed in detail. Our study shows that the depositional environment of the Holocene in this area is represented 4 different sediment types:alluvial deposits,lacustrine and palatal deposits,estuarine deposits,and shallow deposits. The holocene loose deposits and fossil ... |
