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.
