【摘要】 利用MAT -2 71质谱仪对抚顺西露天矿下第三系底煤层所夹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 、O2 、CO2 、Ar等。结合扫描电镜分析 ,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。更多还原

【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, O 2, CO 2, Ar and so on. By systemic analysis of the data from this work and SEM analysis, a conclusion that atmosphere composition of early tertiary can be deduced from the data of components in amber gaseous inclusion.This provides a means in palaeoatmosphere composition study.更多还原
