| 中文摘要:熔体包裹体是岩浆岩中矿物生长或结晶过程中捕获的少量硅酸盐熔体，成为地球深部过程的重要见证者。因此，有效识别其记录的岩浆演化信息显得十分重要。文章在前人对熔体包裹体研究的基础上，系统梳理其研究方法，总结了5步研究过程：① 利用偏光显微镜，开展详细的岩相学观察以识别具有代表性的熔体包裹体类型；② 为加热实验和成分分析制备样品；③ 利用高温热台，对熔体包裹体进行加热实验使其内部均一化，并测得捕获温度；④ 通过电子探针、二次离子探针、LA-ICP-MS、显微激光拉曼等技术对熔体包裹体中的主、微量元素、同位素以及挥发分组成进行分析测试；⑤ 熔体包裹体数据分析，与全岩成分和相关实验得出的流体成分进行对比。虽然熔体包裹体的研究经历了近百年的发展，但有效还原其代表的初始岩浆信息，仍然是当前研究的难点和热点。尤其是地球系统科学发展引发宜居地球深部过程的探讨，使得开展熔体包裹体分析新方法的探讨成为重中之重。 |

| Abstract:Melt inclusions contain small amounts of silicate melts being captured during the crystallization of host minerals in magmatic rocks. Melt inclusions record unique information of the deep processes in the Earth. Therefore, it is very important to effectively to study the petrography of melt inclusions and unravel the encoded geological information. Based on previous studies of melt inclusions, this paper presents an overview of the analytical technqiues for melt inclsuions study, and recommends five steps to carry out melt inclusion study, including ① Using a polarizing microscope to conduct detailed petrographic observations for identifying the types of melt inclusions; ② Preparing samples for heating experiments and component analysis; ③ Loading the samples on a high temperature heat table to conduct heating experiments on melt inclusions to homogenize their compositions and record the temperature corresponding to phase changes; ④ Analysing the major and trace elements, isotopes, and volatile compositions of melt inclusions using Electron Probe Microanalysis, Secondary Ion Mass spectrum, LA-ICP-MS, and Microscopical Raman spectrum techniques; ⑤ comparing the compositon of melt inclusions with the composition of whole rocks and fluid inclusions to understand the magma evolution. Although studies on melt inclusions date back to nearly a century ago, acquisioon of accurate geological information encapsulted in the melt inclsuions remains to be a challenage due to a lack of effective analytical technqiues and the complexity of melt inclusions in nature. The development of Earth System Science initiates an inquiry into a better undersanding of deep process of the earth, and melt inclusions in magmatic rocks can provide an essential tool for probing into the deep earth process. |
