| 摘 要： | 利用X射线荧光和X射线衍射仪,对2007年8—9月取自现代黄河口及其邻近渤海海域的250个表层沉积物中的CaO和蒙皂石含量做了分析。结果表明,CaO和蒙皂石含量平面分布趋势相似,总体呈现由黄河口向东方向逐渐降低的趋势,依次可以划分出莱州湾西部高值区(Ⅰ区)、中间过渡区(Ⅱ区)和莱州湾东部低值区(Ⅲ区)。研究区沉积物中CaO和蒙皂石含量的这种分布特征,主要是黄河入海物质和水动力条件共同作用的结果。因此,该区域CaO和蒙皂石含量的分布不仅能反映黄河入海沉积物的运移,同时,对黄河口区的水动力条件有很好的指示意义。

| Abstract: | A large-scale investigation of surface sediments was carried out off the Yellow River mouth and in the nearby Bohai Sea during August-September 2007. Approximately 250 samples were selected to determine CaO and smectite content using X-ray fluorescence spectrometry and X-ray diffraction. The analyzed data show that the CaO content distribution has similar occurrence to the smectite,which decreases seaward gradually from the Yellow River mouth. The study area can be classified into three provinces in terms o... |
