摘要：

在 CHINARE- 1 5考察期间 ,采集了南极阿德雷岛 Y2湖 67.5cm长的一支湖芯。室内分析测试了部分化学元素的含量 ,与南极西湖沉积物、新鲜企鹅粪、阿德雷岛鸟粪土和南沙太平岛鸟成土的元素特征进行对比后指出该湖泊沉积物为企鹅粪土。元素的聚类分析结果表明该粪土的元素标型组合包括 P、S、Sr、Ba、Cu、Zn、Se、Ca和 F等 9种元素。这为进一步解释其中所记录的气候环境事件提供了依据。

Abstract:

WT5BZ] During CHINARE 15 (12/98-03/99), a 67.5cm lake core had been sampled in Y2 Lake, located in Ardley Island,Antarctica. The concentration of some chemical elements had been analyzed. According to comparative research on elementary character for sediment of Antarctic West Lake, fresh penguin dropping as well as guano soil of Ardley Peninsula and Pacific Island in South China Sea, it presents that the Y2 Lake sediment had been amended by penguin dropping. The result of element cluster analysis shows that the elementary characteristic group for this guano soil includes P、S、Sr、Ba、Cu、Zn、Se、Ca and F, respectively. This provides the base for further interpreting the climatic and environmental event recorded in the sediment.
