摘要
火山岩矿物斑晶中的熔融包裹体是矿物结晶时包裹了原始岩浆而成,未发生泄露和破坏的熔融包裹体可以有效地保存有关原始岩浆中各种物质的实际浓度,其成分代表着原始岩浆的成分,它能比较真实、直接地提供原始岩浆的信息,反映成岩成矿时的物理化学务件和岩浆演化情况,因此对熔融包裹体的研究是火山学研究中的一个重要方面。文章综述了近年来熔融包裹体研究的最新进展和应用,分析了对熔融包裹体的几种检测方法的优缺点,讨论了常见的"岩石学方法"的一些问题。
Melt inclusions in phenocrysts were formed when minerals grew and enclosed primitive magma drops. The melt inclusions which hadn't leaked preserved previous compositions of the primitive magma. The intacted melt inclusions can provide actual and direct information about primitive magma, in the mean time they can reveal the physical and chemical conditions of rock and ore-formation, and magma evolution as well. So it's an important aspect of geology to study melt inclusions. The author summarized the progress in the study of melt inclusions in recent years, and compared the characteristics of several analysis method.s.
