EBSD-Based Calibration of Differential Stress in Experimentally Deformed Quartzite: An All-Grain Perimeter/Area Piezometer Scott E. Johnson (11529496) Won Joon Song (11528941) Walter Sullivan (23134644) Michael Stipp (22150070) Structural geology and tectonics Quartz piezometry Perimeter density Boundary roughness Subgrain wall spacing EBSD Differential stress Recrystallization <p dir="ltr">The data files here have been used in Johnson et al. (2026, Journal of Geophysical Research, in review). They are (1) nine .ctf files of raw EBSD data with 0.2 μm step sizes for experimentally deformed Black Hills quartzite samples, (2) a MATLAB script to reconstruct grains from the EBSD data and calculate the number-weighted perimeter density, (3) a result Excel file including areas, perimeters and aspect ratios of all grains for the nine samples with 0.2 and 1.0 μm step sizes, and (4) a zipped file of high-resolution KAM maps in Figure S1 of Johnson et al. (2026, Journal of Geophysical Research, in review).</p> 2026-09-18T11:32:15Z Dataset Dataset 10.6084/m9.figshare.31252141.v1 https://figshare.com/articles/dataset/EBSD-Based_Calibration_of_Differential_Stress_in_Experimentally_Deformed_Quartzite_An_All-Grain_Perimeter_Area_Piezometer/31252141 CC BY 4.0
