Statement

The experimental and processing methodology for these data is described fully in Cartwright-Taylor A., Main, I.G., Butler, I.B., Fusseis, F., Flynn M. and King, A. (in press), Catastrophic failure: how and when? Insights from 4D in-situ x-ray micro-tomography, J. Geophys. Res. Solid Earth, . Each sample underwent triaxial deformation at 15 MPa confining pressure in our x-ray transparent rock deformation rig. Details of the rig can be found in Butler, I.B., Fusseis, F., Cartwright-Taylor, A. and Flynn, M. (submitted), Mjölnir: a miniature triaxial rock deformation apparatus for 4D synchrotron x-ray microtomography, J. Synchr. Rad. The samples were loaded to failure at a constant strain rate of 3 x 10^-5 s^-1 in a step-wise manner, with steps decreasing from 20 to 5 MPa as failure approached. At each step the stress was maintained and a μCT volume acquired. Each volume was reconstructed by filtered back projection. The sub-volume of interest was then extracted from each volume, de-noised and down-sampled to 16-bit before segmentation and subsequent analysis.
