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。
In this paper, we analyzed the kaolinite from 10 surface sediment clay mineral samples in the Prydz Bay of the Antarctic and the adjacent sea areas using infrared spectroscopy. The results show that the content of kaolinite in surface sediment clays ranges from 2% to 26%, and its distribution characteristics decrease with the increase of the distance from offshore. The relationship between kaolinite content and sediment grain size is positively correlated with coarse sand, middle sand and fine sand, negative correlation with coarse silt, fine silt and clay, indicating that kaolinite content mainly comes from the local , After entering the sea by the sedimentary environment.
