| 摘 要： | 通过海上调查及实验室分析,查明渤海南部表层沉积物在结构类型、矿物组合、生物组分及沉积构造等相特征方面具有明显的分区性。渤海南部存在五种沉积相:黄河水下三角洲相、陆架盆地相、海湾相、潮流浅滩相及古滨岸相。黄河水下三角洲相从河口延至水深15—20米处,沉积速率很高,沉积物富含碎屑云母及CaCo_3。陆架盆地相的沉积为粉砂质粘土,具有生物扰动构造。

| Abstract: | The surfical sediments in various areas of the Bohai Sea display signifcant difference in texture, mineral composition, biogenic detrtius and sedimentary stcurture, which reflects the distinction of sediment source, hydrodynamics, environment, sedimentation rate and geological history. Five sedimentary facies have been determined. They ire the Huanghe River subaqueous delta, the shelf basin, the Laizhou Bay, the tidal banks and the fossil nearshore. The sediments of the first and second facies derived from the Huanghe River; the others are affected by solid discharge and process of the Huanghe River to some extent. |
