Appendix B. EPMA WDS maps: data extraction

Analyses of minerals in chondrules and associated silica-rich igneous rims in CR chondrites. Data are from quantitative wavelength dispersive spectroscopy (WDS) X-ray maps obtained on the JEOL JXA-8530F electron microprobe at the University of Manchester. Powerpoint files show locations of areas extracted from WDS maps: each area is an individual analysis of a mineral grain. Excel files contain extracted data for each location.

对球粒陨石中球粒及伴生的富含二氧化硅的岩浆边界的矿物进行分析。数据来源于在曼彻斯特大学JEOL JXA-8530F电子探针上获得的定量波长色散光谱（WDS）X射线图谱。Powerpoint文件展示了从WDS图谱中提取的区域位置：每个区域均为单个矿物颗粒的分析。Excel文件包含了每个位置的提取数据。
