Source identification of aluminum in surface sediments of the Yellow Sea off the Shandong Peninsula
-
摘要: 本文对采自山东半岛北部近岸海域的表层沉积物进行了粒度和元素测试分析。分析结果表明:研究区表层沉积物主要由粉砂粒级组分构成,其粒度特征同黄河相似。本区表层沉积物中元素铝含量变化范围介于5.57%~7.37%之间,平均含量为6.33±0.40%;此外,其平面变化特征主要受粒度控制。铝钛比值、铝含量、钛含量以及平均粒径之间的相关性分析表明本区表层沉积物中的铝主要来源于陆源碎屑物质的供应,同时还受部分人为源物质的影响。在研究区某些站位,铝钛比值由于受到人为源过剩铝的影响而远大于黄土物质背景值。因此,即使在以陆源碎屑沉积为主的近岸沉积物中运用铝元素作为陆源物质指标时,也应该首先对沉积物中的铝来源进行鉴别。Abstract: Surface sediment samples in the near shore area of the north Shandong Peninsula are collected for grain size and element analyses. The results indicate that the surface sediments in the study area are primarily composed of the silt-sized components similar to the Huanghe River. The total concentration of aluminum varies from 5.57% to 7.37% (average (6.33±0.40)%), and its spatial distribution is mainly controlled by the grain size. Correlations between the ratio of aluminum to titanium concentration and aluminum concentration, titanium concentration and the mean grain size indicate that aluminum in the near shore surface sediments is affected majorly by the terrigenous source, and partially by the anthropogenic source. The ratios of aluminum to titanium concentrations are larger than the background value of loess matter at some stations due to the existence of excess aluminum associated with human activities. Thus, the sources of aluminum should be identified firstly when aluminum is used as an index of terrigenous matter even in the near shore area dominated by terrigenous deposits.
