This dataset is supplemental to the paper Wiesman et al. (In prep) and contains data on the density of dislocations and their stress fields in olivine from laboratory experiments to examine transient creep in olivine. The data were used to characterize the microstructural evolution that occurs during transient creep in olivine. These results can be used to test and calibrate microphysical models for transient creep that will be used to describe how Earth’s mantle responds to changes in stress caused by earthquakes and as melting glaciers.

Data are provided in a zip folder and include:

• Mechanical data from each experiment: ten .txt files of raw data, ten .txt files of processed data

• Measurements of lattice orientation via EBSD: ten .ctf files of large area EBSD maps and ten .ctf files of regions mapped with HR-EBSD

• Densities of geometrically necessary dislocations from the HR-EBSD analysis – ten .txt files of processed data

• Residual stress heterogeneity also determined from HR-EBSD analysis – 20 .txt files of processes data

• Forescatter electron images of decorated dislocations – 49 .tiff files and 49 .png files of decorated dislocations, 44 .pngs of counted dislocations, and one .txt file documenting the counted dislocations
