矿物中玻璃包裹体的成分一般能代表主矿物形成时的岩浆成分,通过包裹体成分研究,可以了解岩浆的演化过程。1972年武内寿久弥、今井秀喜曾用电子探针分析了日本一些矿区酸性火成岩的石英中玻璃包裹体,测得其成分为富硅、贫铁和镁,查明了形成石英晶体的酸性岩浆的本质。 我们通过对一二二○地区火山岩中石英斑晶和晶屑中的玻璃包裹体及其子矿物的电子探针分析,探索了样品制备和实验方法,讨论了实验结果的地质意义。
The composition of the glass inclusions in minerals can generally represent the magmatic composition when the main mineral is formed. Through the study of the composition of the inclusions, the evolution of the magma can be understood. 1972 Kimiko Shouki, Imai Hideki Imagination has been used electron probe analysis of some of Japan’s acidic igneous quartz quartz glass inclusions, measured its composition is rich in silicon, iron and magnesium-rich, identified the formation of quartz crystal acid magma Nature. Through the electronic probe analysis of the glass inclusions and their sub-minerals in quartz porphyrites and crystal chips from 1220 volcanic rocks, we have explored sample preparation and experimental methods and discussed the geological significance of the experimental results.
