Particle images

This folder contains the complete collection of particle images as of February 2025. Each particle image is associated with 33 particle features that can be found in the "Particle_features.xlsx" file. The filename of the particle image corresponds to the index of the spreadsheet row of the associated particle features. Note that the final term of the filename (e.g., JJtrlcf) corresponds to the label. The label contains the particle main type in its first letter: J for juvenile, L for Lithic, A for Altered material, or the name of specific minerals like PG (plagioclase) or PX (pyroxene) for free crystals.

本文件夹收录了截至2025年2月的全部颗粒图像集合。每张颗粒图像均对应33项颗粒特征，相关特征可在"Particle_features.xlsx"文件中查阅。颗粒图像的文件名与对应颗粒特征在电子表格中的行索引保持一致。请注意，文件名的最后一段（例如JJtrlcf）即为其对应的标签。标签的首字母代表颗粒的主要类型：J代表幼年颗粒（juvenile），L代表岩屑（Lithic），A代表蚀变物质（Altered material）；若为自由晶，则标签采用对应矿物的英文缩写，例如PG代表斜长石（plagioclase）、PX代表辉石（pyroxene）。
