Characteristics and provenance of rare earth element in mud wedge in the sea area north of Shandong Peninsula since 2 ka

摘要:
山东半岛泥楔是连接渤海和黄海的关键沉积体，在中国海域的沉积体系中占有重要地位，也是中国陆架边缘重要的“源-汇”体系中不可或缺的一环。通过分析位于山东半岛北部海域泥楔ZZ04柱状样的AMS 14C测年、沉积物粒度以及稀土元素含量等，探讨研究区稀土元素的控制因素以及泥楔沉积物的来源。结果表明，ZZ04柱状样的沉积物类型以粉砂为主，物质组分相对单一，在剖面上，粒度自下而上呈现由细至粗的变化过程。稀土元素经球粒陨石标准化后，显示出轻稀土富集而重稀土相对稳定的右倾“V”字型特征，为明显的陆源型特征。进一步将ZZ04与周围河流的稀土元素进行上陆壳标准化后对比分析可知，ZZ04与黄河的配分曲线较为相似，而与韩国河流以及山东半岛河流的配分曲线差异较大。此外，通过对稀土元素与粒度进行相关性分析，结合两者曲线的对比分析发现，2 ka以来，山东半岛泥楔的稀土元素分布受“粒度效应”的影响，泥楔的物源主要来自黄河。在现代海洋环流体系建立后，黄河携带的细粒沉积物沿着山东半岛北部沿岸流向东穿过渤海海峡进入黄海。在此过程中受到由南向北的黄海暖流的顶托作用，流速降低，导致大量细颗粒物质在山东半岛北部海域沉积，并形成“Ω”型的独特水下三角洲。
Abstract:The mud wedge in the Shandong Peninsula serves as a pivotal sedimentary body, linking the Bohai Sea with the Yellow Sea. It plays a significant role in the sedimentation system of China seas as an essential component of "source-sink" system in the edge of the Chinese continental shelf. The controlling factors of rare earth elements (REEs) and the provenance of the wedge sediment in this area were studied based on the analysis of AMS 14C dating, grain size, and REEs content of the ZZ04 boxcore samples at the northern offshore of the Shandong Peninsula. Results indicate that the boxcore samples consist of mainly silty sand in relatively simple material composition with a trend of coarsening in grain size from deeper to shallower depths. Upon normalization with chondrites, the REEs exhibit a characteristic enrichment of light rare earth elements (LREEs) and relative stability of heavy rare earth elements (HREEs), forming a distinct right-leaning V-shaped pattern indicative of a clear terrigenous signature. Further comparative analysis on the REEs between the ZZ04 sample and surrounding rivers’ after continental crust normalization revealed that the distribution patterns of ZZ04 samples closely resemble those of the Yellow River. In contrast, they show significant differences from those of the rivers in South Korea and the Shandong Peninsula. Additionally, correlation analysis between REEs and grain size suggested that the distribution of REEs in the mud wedge is influenced by the "grain size effect" since approximately 2,000 years ago. The source of the mud wedge comes mainly from the Yellow River. After the establishment of the modern ocean circulation system, the fine-grained sediments carried by the Yellow River flowed eastward along the northern coast of the Shandong Peninsula through the Bohai Strait into the Yellow Sea, and then encountered by the northward Yellow Sea Warm Current, which decreased the flow velocity and resulted in the settlement of a large amount of fine-grained matter in the northern waters of the Shandong Peninsula, forming a unique Ω-shaped underwater delta.
