摘    要:对近2 ka以来闽浙沿岸泥质沉积物进行了粘土矿物和元素测试,粘土矿物对比分析表明,所研究的泥质沉积物来源为长江沉积物.金属元素聚类分析以及使用判别函数,均得到了与上述一致的结果.沉积物物源的定量计算表明,近2 ka以来闽浙沿岸泥质沉积物中长江的贡献基本稳定在83%~85%,可以排除有黄河沉积物输入的可能,且历史上黄河的改道与北徙并没有对本区的沉积环境和沉积物来源产生明显的影响.

关 键 词:闽浙沿岸泥质沉积物  粘土矿物  元素地球化学  物源

Abstract:The clay minerals and elementsof the mud along the Min-Zhe Coast since 2 kaBPare analyzed. The provenance of the mud is from sediments of theYangtze River accordingto the study of clay minerals. The same results are drawn based on cluster analysis and differentiationfunction of metal elements. It is about 83%~85% of the mud from sediments of the Yangtze River since 2 kaBP according to quantitativecalculation, and sediments of the Yellow River did not reach the study area. It also shows that there isno apparent effect on the sedimentary environment and sediment provenance when the Yellow River changed its course and moved northward during the last 2 ka.
Keywords:mud along the Min-Zhe Coast  clay minerals  elements geochemistry  provenance
