渤海东部与黄海北部表层沉积物的粒度特征及其沉积环境
发布时间：2019-06-25 14:09
【摘要】：渤海东部和黄海北部表层沉积物粒度组成分析揭示,沉积物主要由砂、粉砂、粉砂质砂和砂质粉砂组成,部分海域出现含砾沉积物。总体分布表现为南细北粗、东西分带的特点,形成以平行岸线的条带状分布格局为主体的南北不同的镶嵌形态,由岸及海、由北向南呈现由粗到细的分布特征。沉积物分布主要受物质来源、地形以及海洋环流控制,根据沉积物成因划分出老铁山水道-辽东-渤中浅滩砂质沉积区、山东半岛沿岸流泥质沉积区、北黄海中部泥质沉积、南黄海中部泥质沉积区、西朝鲜湾潮流沙脊沉积区、渤海中部泥质沉积区,并讨论了不同沉积区的沉积环境。
[Abstract]:The analysis of grain size composition of surface sediments in the eastern Bohai Sea and the northern part of the Yellow Sea shows that the sediments are mainly composed of sand, silty sand and sandy silt, and gravel-bearing sediments appear in some sea areas. The overall distribution is characterized by the thickness of the south and the north and the zoning between the east and the west, forming different mosaic patterns between the north and the south with the banded distribution pattern of the parallel shoreline as the main body, showing the distribution characteristics from thick to fine from north to south from the shore and the sea. The sediment distribution is mainly controlled by material source, topography and marine circulation. According to the sediment genesis, the sediment distribution is divided into Laotieshan waterway-Liaodong-Bozhong shoal sandy sedimentary area, Shandong Peninsula coastal fluvial muddy sedimentary area, the north Yellow Sea middle muddy deposit area, the southern Yellow Sea middle muddy sedimentary area, the West Korean Bay tidal current sand ridge sedimentary area, the Bohai Sea central muddy sedimentary area, and discusses the sedimentary environment of different sedimentary areas.
