| 摘 要： | 对南海台西南海域表层沉积物的常量、微量元素含量分布变化特征、元素相关性以及元素组合特征进行了分析。结果表明,SiO2和Al2O3是研究区表层沉积物中的最主要组分,元素的含量与水深、粒度存在明显的相关性;R型因子分析识别出3个元素组合,分别代表细粒的陆源碎屑沉积组合、粗粒的生物碎屑组合和细粒的生物碎屑组合;研究区表层沉积物的物质来源主要有陆源和生物源两种,以陆源为主。

| Abstract: | Element distribution,corrections and assemblages of surface sediments from Taixinan area in the northeastern South China Sea are studied in the article.The results show that SiO_(2) and Al_(2)O_(3)are the most important components in the surface sediments,that element contents change with water depth and granularity,that R fator analysis gives three assemblages which represent fine-grained terrestrial chips,coarse-grained biological materials and fine biological materials,and that genetically surface sediments in the studied area mostly come from continent and secondly from biology. |
