利用琥珀气体包裹体判断古大气成分方法研究

Method Research for Deducing Palaeoatmosphere Composition from Components of Amber Gaseous Inclusion

摘要: 利用ＭＡＴ－２７１质谱仪对抚顺西露天矿下第三系底煤层所平琥珀样品中的气体包裹体成分进行分析，结果表明包裹体主要成分为ＣＨ４、Ｎ２、ＣＯ２、Ａｒ等。结合扫描间分析，对实验结果作了系统分析和整理，认为琥珀包裹体气体成分能够在一定程度上反映该区早第三纪古大气组成，使用琥珀气体包裹体成分分析古大气成分的方法是可行的。

Abstract: In this paper the determination of components of gaseous inclusion in amber from the bottom of tertiary coal bed in Fushun strip coal mine by MAT 271 mass spectrograph was reported. The results show that the main components of inclusion are CH 4, N 2,
