Abstract

Abstract:

This study applies confocal Raman microscopy to conduct 3D imaging of methane-bearing fluid inclusions in eclogites from the Chinese Western Tianshan high-pressure/ultrahigh-pressure metamorphic belt, precisely delineating the morphology and spatial distribution of distinct phases. Based on the imaging data, ImageJ software was employed to perform volumetric quantification and mass calculations of the inclusion components. We present a comprehensive practical guide encompassing instrument operation, data processing, parameter optimization, and quantitative calculation workflows. These protocols offer a valuable resource for researchers investigating 3D Raman quantitative methods, thereby facilitating the acquisition of precise quantitative data in geological fluid research.

Key words:

fluid inclusions, 3D Raman imaging, quantitative analysis, eclogite, Western Tianshan high-pressure/ultrahigh-pressure metamorphic belt

摘要：

利用激光共聚焦拉曼光谱仪, 对西天山高压–超高压变质带榴辉岩中含甲烷流体包裹体开展三维拉曼成像, 精确地揭示不同成分相的形态及空间分布特征, 并针对相应的流体包裹体成分, 利用ImageJ软件进行体积定量和质量计算。给出详细的仪器操作、数据处理、参数设置和定量计算实操指南, 可为寻求拉曼3D定量处理方法的研究者提供帮助, 进而为地质流体的研究提供精确的定量化数据支持。
