摘要
在无产阶级文化大革命的推动下,为使海洋科学研究更好地为无产阶级政治服务,为工农兵服务,密切结合有关的生产实践,近几年来,我们与河北省地质局第七地质大队和天津中队协作,参加了河北平原(以黑龙港地区为重点)地下水资源评价与合理开发勘探的研究工作,其中涉及到了海相地层与海岸线问题。关于渤海湾西岸海相地层与海岸线问题的研究,不仅对该地区浅层地下水开发和咸水改造利用具有实际意义,而且对渤海形成历史的探讨也具有一定的关系。
Three marine formations are recognized from the Quaternary sediments(above 100 meters)of the western coast of the Gulf of Bohai.The Cmethod and paleomagnetic measurements were used to estimate the age for each marine formation.The first marine formation existed between 102,000—70,000 yrs B.P.belonging to Riss-Würm interglaciation.The second was between 39,000—23,000 yrs B.P.corresponding to the interstadial of Würm glaciation.The third was between 8000—2000 yrs B.P.corresponding to the postglacial deposition.The three marine formations indicated that three transgressive sequences occurred in the western coast of Bohai Gulf.The first transgression reached the vicinity of Xiegongting in the western part of Changzhou city,here termed Changzhou transgres-sion.The second transgression is greater in extent than the first,its boundary could reach Xianxian country,here termed XianXian transgression.The third transgression here termed Huanghua transgression,is less in extent than the first and the second,and is distributed only in the zone of Huanghua,Zhinghai,Tianjin(Tientsin).There-fore,we recognized three paleo-coastline in this area.
