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。本文根据71个水文钻孔的野外与室内分析资料,对海相地层的一般地质特征与 Under the impetus of the Great Proletarian Cultural Revolution, in order to make maritime scientific research better serve the proletarian politics, serve the workers, peasants and soldiers, and closely integrate the relevant production practices, in recent years we have worked closely with the Seventh Geological Brigade of Hebei Bureau of Geology Tianjin Squadron collaborated to participate in the research on the groundwater resources evaluation and rational exploration and development in Hebei Plain (focusing on Heilonggang region), which involved the issue of marine strata and coastline. The research on the marine strata and coastline in the west coast of the Bohai Bay not only has practical significance for the development of shallow groundwater and utilization of saltwater in the area, but also has a certain relationship with the exploration of the formation history of the Bohai Sea. Based on the field and indoor analysis data of 71 hydrological boreholes, this paper analyzes the general geologic characteristics of marine strata
