摘要

摘要: 通过对山东半岛东部海域表层沉积物常量、微量元素、有机碳(TOC)以及碳酸盐(CaCO₃)等指标的分析,研究了该海域表层沉积物元素组成特征及其控制因素,并对物质来源进行了探讨。结果表明,山东半岛东部海域表层沉积物元素的平均组成与上陆壳(UCC)相比Al,K,Na,Mg,Fe,Ca,Cu和Zn等元素,相对较低,而Mn,Co,Ni,Cr以及REE元素含量较高,Si和Ti与UCC的含量相当。研究区砂粒级沉积物轻重稀土分异明显,(La/Yb)_N值与韩国河流的非常相近;其余粒级沉积物LREE分异较弱,标准化曲线与黄河沉积物的具有相似性。研究区沉积物的元素含量主要受控于源岩组成,存在明显的"粒级效应"。除此之外,Fe-Mn氧化物、生物碳酸盐等因素对元素组成产生一定影响。沉积物物源判别结果显示,山东半岛近岸及其东南部沉积物主要来源于黄河,该区域沉积物分布受山东半岛沿岸流及近岸潮流影响。研究区东北部为残留砂,其沉积物元素组成特征与朝鲜半岛和鸭绿江沉积物组成相近,表明研究区东北部砂质区沉积物代末次冰期低海平面时可能由朝鲜半岛或鸭绿江供应。

Abstract: The contents of main and trace elements, total organic carbon (TOC) and carbonate are reported in sediments recovered from the offshore areas of the Shandong Peninsula.The aims are to understand the provenance and diffusion pattern of the sediments by the element composition characteristics.The results indicate that the content of some elements, such as Al, K, Na, Mg, Fe, Ca, Cu and Zn is higher in the offshore areas than in the upper continental shelf (UCC), and the content of Mn, Co, Ni, Cr as well as rare earth element (REE) is lower.Si and Ti in the offshore areas are same as UCC.HREE fractionates obviously in sand and the value of c_n(La)/c_n(Yb) is close to that of Korean rivers.The normalized curve of other sediments is same as that in the Huanghe River and different from that in the Changjiang River.The element composition mainly is controlled by source rocks and influenced by granularity.Furthermore, Fe-Mn oxides and biogenous carbonate also exert some influence on the element composition.The result of provenance discrimination exhibits that the sediments offshore and in the southeastern area are mainly derived from Huanghe River.Where the transportation pattern of sediment is controlled by Shandong Peninsula coastal current and tide.The coarse sediments in the northeast mainly are the relict sands and their element component is same as that of the Korean Peninsula and the Yalu River.This means that the coarse sediments in the northeast may be supplied by the Korean peninsula or the Yalu River in the last glacial when the sea level was low.
