| 摘 要： | 应用X射线衍射(XRD)方法对滦河口表层沉积物黏土矿物组分进行分析,结果表明,研究区黏土矿物中伊利石相对百分含量最高(46%~61%,平均56%),蒙脱石和绿泥石次之(蒙脱石15%~36%,平均25%;绿泥石8%~14%,平均11%),高岭石含量最低(5%~11%,平均8%),黏土矿物组合类型为伊利石-蒙脱石-绿泥石-高岭石型;滦河口表层沉积物中的黏土矿物主要为来自滦河的陆源物质,渤海湾环流有可能为研究区带来黄河物质,同时,研究区为辽东湾及渤海北部提供物源供给。

| Abstract: | Surface sediments from the Luan River Estuary were analyzed with XRD for clay mineralogy. Results show that illite (46-61%, 56% on average) dominates the samples with smectite (15-36%, 25% on average) and chlotite (8-14%, 11% on average) as the second and kaolinite (5-11%,8% on average is) the lowest. The assemblage of illite-smectite-chlotite-kaolinite is the dominant clay minerals assemblage in the area. The clay minerals in the surface sediments of the Luan River Estuary are mainly terrigenous in origin. The Bohai Bay circulation may bring some materials from the Yellow River to the region. At the same time, the study area also acts as the material source for the Liaodong Bay and Northern Bohai Bay. |
