幔源岩流体包裹体气态物质组成质谱分析

MS Analysis of Chemical Composition of Gas from Mantle Xenoliths

采用分步加热法收集慢源岩流体包裹体中的气态物质，并用质谱计分析了这些气态物质的组成。本文主要介绍分析过程，并给出个别结果。

Gases from mantle xenoliths have been collected by step-heating method and have been analysed by MS. In this paper, we introduce the courses of analyses and present some results.
