| 摘 要： | 本文用X-射线衍射法直接计算了来自黄河三角洲沿岸及邻近海区80个沉积样的细粒组分(<2μm)中的碳酸盐含量。计算结果与全样的容量法分析结果基本一致。研究结果表明,本区细粒沉积物中碳酸盐含量变化受沉积物来源、海区水动力作用、海底地貌特征和碳酸盐的地球化学行为等因素所影响。

| Abstract: | The carbonate content of 80 samples from the coastal zone of the Huanghe Delta and adjacent Bohai Gulf was calculated by X-ray diffraction method. The results are similar to those of volumetric analysis.The results show that the changes of carbonate content in the fine grained sediment are controlled and influenced by the sources of sediments, the dynamics of sea water, bottom morphology and the geochemical behaviour of carbonate. Carbonate is an indicater for the migration and dispersal of the silt carried into the sea by the Huanghe River which rich in carbonate. |
