扫描电镜配合能谱分析、X射线衍射及光学显微镜分析表明,黄河口毗邻的渤海陆架区悬浮体主要由矿物、浮游生物和有机包膜三类成分组成。在悬浮体中鉴别出23种矿物,主要是石英、长石、云母、方解石和粘土矿物(依次为伊利石、蒙皂石、绿泥石和高岭石),特征矿物是云母、方解石、蒙皂石和角闪石。辨识出21种藻类,大多数是硅藻,少数为钙藻和鞭毛藻。生物成分主要集中在水体上层。首次在渤海悬浮体中发现了有机包膜。并讨论了悬浮体成因及其沉积作用。
Scanning electron microscopy coupled with energy dispersive spectroscopy, X-ray diffraction and optical microscopy analysis showed that the suspended sediments in the Bohai shelf adjacent to the Yellow River Estuary are mainly composed of minerals, plankton and organic envelopes. Twenty-three minerals were identified in the suspension, mainly quartz, feldspar, mica, calcite and clay minerals (followed by illite, smectite, chlorite and kaolinite) and the characteristic minerals were mica, calcite, Stone and hornblend. 21 species of algae were identified, most of them were diatoms, and a few were calcium algae and dinoflagellates. Biological composition is mainly concentrated in the upper body of water. For the first time in the Bohai Sea suspended organic found in the capsule. The causes of sediment and its deposition are discussed.
