This code and data supports the publication "Transient and steady-state dislocation creep of olivine controlled by dislocation interactions at the isostress endmember" by David Wallis, Thomas Breithaupt, and Taco Broerse.

This deposit consists of the following structure and files:

• Top-level folder:

  • This descriptive file, README.txt,
  • MATLAB scripts to produce each of the subfigures in the paper (e.g., Figure1.m, etc.),
  • A Microsoft Excel XLSX file, KeefnerFullData.xlsx containing the mechanical data of Keefner et al. (2011, Journal of Geophysical Research: Solid Earth),
  • A MATLAB script, Aheim.m, written for the toolbox MTEX to import electron backscatter diffraction data from Aheim dunite into MATLAB.

• Aheim folder:

  • Electron backscatter diffraction data collected on Aheim dunite as paired CPR and CRC files. The files appended with "_NR" have undergone noise reduction. These files can be opened in MATLAB using the freeware toolbox MTEX and in proprietary software distributed by Oxford Instruments (e.g., Channel 5 or AZtec).

• Functions folder:

  • Contains the MATLAB functions used to plot the figures.

• Figures folder:

  • Contains SVG files of the figures saved from MATLAB. These files can be opened in the freeware Inkscape.

• Figure_completion folder:

  • Contains the SVG files used to edit the raw SVG files saved from MATLAB in the Figures folder, along with PNG files of the final figures.

• Colourmaps folder:

  • Contains MATLAB scripts defining the colourmaps used to plot the figures with associated documentation.

Many of these scripts require the freeware MTEX toolbox for MATLAB, which can be downloaded at: https://mtex-toolbox.github.io/download.

The scripts were tested with MTEX version 6.0.
