| 摘要: |
| 本文利用红外光谱法对南极普里兹湾及毗邻海域10个表层沉积 物粘土矿物样品中的高岭石作了分析。结果表明,该区表层沉积物粘土中高岭石含量在2—26%之间,其分布特征随离岸距离的增加而降低。高岭石含量与沉积物 粒级的关系是与粗沙、中沙和细沙呈正相关关系;与粗粉沙、细粉沙和粘土呈负相关关系,并说明高岭石含量主要来自南极本地,入海后受沉积环境的牵制。 |

| THE INFRARED SPECTRAL ANALYSIS OF KAOLINITE IN THE CLAYMINERALS OF SURFACE SEDIMENT FROM PRYDZ BAY ANDADJACENT SEA AREA,ANTARCTICA |
|

| Abstract: |
| The clay minerals sampled from 10 surface sediments of prydz bay and adjacent sea area, Antarctica were analysed by infrared spectrum. The result shows that clay minerals contain Kaolinite (2-26%), the content of which decreases with the distance away from the coast and is positively related with the coarse, medium and fine sands, inversely with crude dust sands, fine dust sands and clay. The source, migration and feature distribution of Kaolinite in the area are also discussed. |
