火山岩中熔体包裹体研究进展

A Review on Research Progress of Melt Inclusion in Volcanic Rocks

火山岩斑晶矿物中保存完好的熔体包裹体含有原始熔浆的成分和挥发分含量,带有原始岩浆的信息,是恢复火山喷发前岩浆化学成分和了解岩浆作用过程及源区特征的最好工具。本文概述了熔体包裹体研究的发展历程和国内外研究进展及应用,总结了目前对熔体包裹体的分析测试仪器,还对熔体包裹体均一实验和熔体挥发分及脱气作用展开了充分讨论。随着现代测试仪器精度的不断提高和测试应用范围的扩大,熔体包裹体研究从传统的高温热台研究转向地球化学研究和应用领域,可以更好地解释岩浆过程中的地质现象、了解岩浆演化,目前熔体包裹体的研究已进入更快发展阶段。

The intact melt inclusion well preserved in phenocrysts of host volcanic rocks contains primary magma and volatile components,with the recorded information of the primary magma. It is the best medium to reconstruct the magma composition prior to eruption as well as to understand magmatic process and source characteristics of the magma. This paper has briefly summarized the development process,research progress,and application at home and abroad on the research of the melt inclusion,described various instruments for analyzing the melt inclusions,and fully discussed the questions concerning the homogenization test for the melt inclusion, the volatile components in the melt,as well as the degasification of the magma. With the continuous improvement of the precision of modern instruments and the expansion of the test applications,the melt inclusion research target has been moved from the traditional high temperature heating stage experiment to the geochemical research and the related application,in order to make better interpretation on the geological phenomena by the magmatic process,and to deeply understand the magma evolution. At present,the melt inclusion research has entered in a fast developing stage.
