Failure Modes of Asperities in Rock Discontinuities
… between the peak shear strength of the rock joints and the applied normal stress.

Investigating the Evolution of Rock Discontinuity Asperity Degradation and Void Space Morphology under Direct Shear
Rock mass discontinuities represent planes of relative weakness and enhanced hydraulic conductivity and, thus, have a substantial influence on the hydro-mechanical behaviour of the overall rock mass. While the shearing of rock mass discontinuities has been extensively studied in the past, there …

The structural and engineering geology of the Country Rock at Finsch Mine
… information to build a database for the country rock. The country rock is comprised of the ~2.5 Ga sediments of the Griqualand West Basin: the banded ironstones and carbonates of the Ghaap Group. A stratigraphic column has been produced that correlates the country rock at Finsch Mine with the …

Large-scale hydrothermal dolomitisation in the southwestern Cantabrian Zone (NW Spain) : causes and controls of the process and origin of the dolomitising fluids
… in several thin-skinned thrust units. The rocks underwent deformation, diagenetic to epizonal thermal events, and several episodes of fluid-flow. A spectacular product of fluid circulation in this area is a large-scale dolomitisation, mostly affecting the carbonates of the Late …

Modeling Roughness of Rock Discontinuity Surfaces
… to propose a new methodology of quantifying the rock discontinuity condition of roughness through the physically based modeling approach of signal analysis. The development of this method came about after investigation into the use of qualitative categorizations of roughness from the RMR rating …
