Experimental friction dataset for heterogeneous and homogeneous mixed quartz-clay fault gouge layers (NERC Grant NE/P002943/1)
The data are from a suite of friction experiments performed on simulated fault gouges comprised of clay-quartz mixtures, sheared in a direct-shear arrangement. Some experiments were performed on gouge layers comprised of adjacent patches of kaolinite-clay and quartz (i.e. heterogeneous gouge layers), whereas others were performed on homogeneous mixtures of the two materials (i.e. homogeneous gouge layers). More information on the different types of experiment is provided in the accompanying metadata for this dataset. The relative proportions of clay and quartz were varied in different experiments. All experiments were performed at an effective normal stress of 40 MPa. The sliding velocity was stepped between 0.3 and 3 microns/s every 1 mm of displacement to calculated the rate-and-state friction parameter (a-b). The evolution of shear stress was monitored with increasing displacement (up to a maximum displacement of 8.5 mm).

Data were collected by shearing gouge layers in a direct-shear arrangement within a high-pressure triaxial deformation apparatus. Normal stress is applied by the confining pressure and pore fluid pressure is introduced to the gouge layer through sintered steel porous disks on each direct-shear forcing block. The forcing blocks are displaced, and thus the gouge layer is sheared, by the axial piston of the triaxial apparatus. An internal force gauge within the axial piston measures the axial force, which is used to calculate the shear stress acting on the gouge layer.
