Statement

20mm x 40-70mm core plugs sampled from the GGC01 borehole were used for geomechanical testing in University of Liverpool's Rock Deformation Laboratory. All fabrics observed were sub-perpendicular to the drillcore axis so that maximum compressive stress in triaxial tests and tensile strengths are measured at 90° to these fabrics. Porosity was measured prior to testing using a helium pycnometer. In compressional experiments, cores were tested in a triaxial deformation apparatus. Samples were saturated with pore fluid at 2.5MPa and confining pressures were held at 6MPa. Permability was determined using the pulse-transient method. Tensile strength was measured on rock discs via a Brazilian test jig in a uniaxial press. Spare material was crushed to <125 microns and sheared between two porous metal plates to determine frictional strength. Crushed material was also used for XRD analyses.
