渤海湾西岸是我国典型的泥质海岸带地区。相对于基岩和砂砾质海岸,泥质(及泥砂质)海岸带对于地质环境变化更为敏感,变化记录的保存更为完整。因此,泥质海岸带一向是地质学家高度关注的研究对象。近年来,随着对“全球变化”的重视日益增强,国际泥质海岸带地学研究涉及的高分辨率地质记录、海陆变迁、海面升降史与高精度测年,均取得了长足的 The west coast of Bohai Bay is a typical muddy coastal zone in China. Relative to bedrock and gravel coasts, muddy (and silty) coastal zones are more sensitive to changes in the geological environment and more complete in preservation of change records. Therefore, the argillaceous coastal zone has always been a highly studied geologist. In recent years, with the increasing emphasis on “global change ”, high-resolution geological records, land-sea changes, history of sea surface movements and high-precision dating of the international argillaceous coastal zone geosciences have made great strides
