摘    要:泥质区沉积记录是全新世海洋环境演变的重要信息载体。中国近海沿岸发育着若干小型泥质沉积体,比较明确的有南海西部近海的泥质区,但尚未进行研究。通过对山东半岛南部近岸海域采集的浅地层剖面资料精细解释后发现,在该区近岸海域存在一个小型泥质沉积区,主要分布在青岛崂山头以北至乳山口附近的近岸海域,整体上平行海岸线呈条带状分布,由近岸向海逐渐变薄,等厚深度分布平行于岸线,沉积中心位于鳌山湾海域,沉积中心最厚可达22.5 m。AMS14C测年结果表明,该泥质区形成于全新世。本文利用在泥质区采集的表层沉积物的粒度、黏土矿物、碎屑矿物、地球化学元素等分析测试结果,对比研究区周边主要入海中小河流物质成分和黄河物质成分,探讨了山东半岛南部近岸海域泥质沉积区的沉积特征和物源情况。结果表明,该泥质区的形成是黄河与周边入海河流共同作用的结果。

关 键 词:山东半岛近岸  泥质区  物源

Abstract:The sedimentary record of mud areas is an important carrier of information on the Holocene evolution of marine environments. Based on fine interpretations of the shallow stratigraphic section data, a small mud deposit area has been found in the southern coastal waters off Shandong Peninsula. This mud area is mainly distributed in coastal waters north of Laoshantou to the vicinity of Rushan Estuary. Overall, it is parallel to the coastline and spreads in a banded pattern, gradually thinning from offshore to the sea. The isopach map of depth distribution is parallel with the shoreline, and the depocenter lies in coastal waters of the Aoshan Bay where the maximum thickness is up to 22.5 m. Accelerator mass spectrometry (AMS) 14C dating shows that the mud area was formed in the Holocene. The test data of surface sediments from the mud area, including particle size, mineral characteristics, and rare earth element contents, are used in comparisons with the composition of materials from the major surrounding medium and small rivers flowing into the sea and the Huanghe (Yellow) River. In this paper, the sedimentary characteristics and provenance of the mud deposit area are discussed. The results show that the formation of this mud area resulted from the joint action of the Huanghe River and surrounding rivers flowing into the sea.
Keywords:southern coastal waters off Shandong Peninsula  mud area  provenance analysis
