Samples were manufactured in both bedding parallel and bedding-normal orientations, except in the coal, where no samples were successfully manufactured with the cylinder axis parallel to layering. After sample manufacture, each sample was dried to constant mass ( dm/dt < 0.01g/day) and was characterised in terms of helium porosity and density. X-Ray Diffraction was used to determine the mineralogy of these sample materials as volume percentages. The stress-dependent permeability was measured using the oscillating pore-pressure technique as described by Turner (1958); Kranz et al. (1990); Fischer (1992); Bernabe et al. (2006); Song and Renner (2007); McKernan et al. (2017). Argon gas was the pore fluid.
