Statement

The samples underwent triaxial deformation at 25 MPa confining pressure and 5 MPa pore pressure in Stór Mjölnir, our x-ray transparent rock deformation rig with integrated acoustic monitoring (Cartwright-Taylor et al., in prep.). The samples were both loaded initially at a constant strain rate of 10⁻⁵ s⁻¹. CL04 continued to be loaded at a constant strain rate of 10⁻⁵ s⁻¹ until it experienced abrupt shear failure. CL10 was loaded in this way until detection of sufficient acoustic emissions to maintain a constant AE event rate of 1 AE s⁻¹, whereupon the sample experienced yield and slow shear failure. In each case, tomographic volumes of the whole sample, comprising overlapping scans of the top and bottom, were acquired every 85 s. At each end of the sample 0.3 mm was not captured due to limits on the x-ray field of view .
