Magma mush eruptibility: groundmass crystal shapes (NERC Grant NE/T000430/1)

Summary

Thin section scans (XPL and PPL) of volcanic rocks studied in the "Mush Eruptibility" NERC project (NE/T000430/1): Mt. St. Helens volcano Washington USA and Santiaguito volcano Guatemala 2) BSE images of volcanic groundmass, acquired at the GJ Russell Electron Microscopy Facility at Durham University in 2020-21. 3) ImageJ (Schneider et al., 2012) overlays containing length and width measurements of plagioclase groundmass crystal intersections for each region of interest (ROI) 4) Length and width data for groundmass plagioclase crystals <100 um in each sample, as reported and discussed in Mangler et al. (2022)
