摘要

摘要: 对山东半岛东北部滨浅海区海底表层沉积物的粒度和矿物组分进行了分析,探讨了其物源及其粒度分布特征与沉积动力条件的关系。结果表明,本区表层沉积物主要来源于现代黄河物质,底质类型主要有黏土质粉砂、砂质粉砂和粉砂质砂3种类型,其中黏土质粉砂约占该区沉积物分布面积的60%以上,呈"Y"形由西北向东南展布。研究区沉积作用的主控因素是黄海沿岸流,各粒级组分的分布和粒度参数特征与海流的方向和强弱有明显的相关性。

Abstract: Analyses of grain size and mineral components of surface sediments in the offshore area of the northeastern Shandong Peninsula were carried out to reveal the sediment source and the relationship between the characteristics of grain size distribution and sedimentary dynamic conditions in the littoral zone off the northeastern Shandong Peninsula. The results indicate that the surface sediments are mostly derived from the Yellow River and can be divided into three types including clayey silt, sandy silt and silty sand. Among them, clayey silt covers more than 60% of the study area, spreading from northwest to southeast in the form of letter "Y", and the Yellow Sea coastal current is the main factor controlling the grain size characters in the study sea area, with the distribution of particle fractions and grain-size parameters being associated closely with the direction and intensity of the Yellow Sea coastal current.
