    摘要
  • 对采集于胶州湾内的2个柱状样进行了粒度、210Pb测年等实验测试,分析其粒度特征并结合计算得出的沉积速率探讨其环境意义。结果表明:胶州湾浅表沉积层具有双层结构,上部为黏土质粉砂,反映了沉积动力较弱的海湾相沉积环境;下部为含砾中-粗砂,反映了沉积动力较强的河流相沉积环境。上部海湾相沉积速率的差异反映了沙脊区水流速度较小,淤积厚;潮沟水道内水流速度较大,淤积薄。
    Grain-size analysis and 210Pb dating have been carried out for the sediment samples taken from the two cores drilled in the Jiaozhou Bay. The characteristics of grain-size and their environmental implications are discussed in combination with the sedimentation rate. The results suggest a bilayered structure in the shallow deposits of the Jiaozhou Bay. The upper layer is composed of clayey silt, indicating a weak dynamic environment, whereas the lower layer is composed of gravel-sand and medium coarse sand, indicating a strong dynamic environment. High sedimentation rate is usually related with the sand ridge deposits. Instead, low sedimentation rate is found in channels.
