| 摘 要： | 利用2006在鸭绿江河口西汊道采集的编号为YLJ-40的样品的平行样,选取了40个样品对柱状沉积物中0.063～0.125 mm粒级的重矿物特征进行了矿物学的分析与测试,重矿物30种,包括铁矿类4种、主要造岩矿物6种、帘石类5种、辉石与闪石类6种、变质矿物9种（包括指示性重矿物4种）。重矿物的沉积记录显示出西水道海陆交互的沉积历史,结合210Pb测年数据和前期研究成果,揭示了该区域近百年来人类活动对河床演变的深刻影响。

| Abstract: | The mineralogical characteristics of heavy mineral of core sediments from forty samples collected in the estuary of the Yalu River in 2006 were analyzed and tested.Thirty kinds of heavy minerals including 4 kinds of iron ores,6 kinds of main rock-forming minerals,5 kinds of epidote groups,6 kinds of pyroxene and tremolite groups,6 amphibole groups and 9 kinds of metamorphic minerals（including 4 kinds of indicative heavy minerals） were found.The sedimentary record reflects the sedimentary history of the land and sea interactions.Combined with 210Pb dating data and preliminary results,the research reveals the deep influence of human activities on riverbed evolution in the region over the past century. |
