Simulating spatial and temporal evolution of multiple wing cracks around faults in crystalline basement rocks [PDF]

open access: yes, 2007
Fault zones are structurally highly spatially heterogeneous and hence extremely complex. Observations of fluid flow through fault zones over several scales show that this structural complexity is reflected in the hydrogeological properties of faults ...

Comparing rockfall scar volumes and kinematically detachable rock masses [PDF]

open access: yes, 2017
Scenario-based risk assessment for rockfalls, requires assumptions for different scenarios of magnitude (volume). The magnitude of such instabilities is related to the properties of the jointed rock mass, with the characteristics of the existing ...

Piping and woody plants in peatlands: Cause or effect? [PDF]

open access: yes, 2005
This paper presents, for the first time, evidence to show that Calluna species are one causative factor of piping in blanket peat catchments. Ground-penetrating radar survey on 960 plots illustrated that piping was prevalent throughout blanket peats ...

Structural history of the southwestern corner of the Kaapvaal Craton and the adjacent Namaqua realm: new observations and a reappraisal [PDF]

open access: yes, 1991
The rocks along the southwestern margin of the Kaapvaal Craton were deformed up to 7 times during the Early to Middle Proterozoic. The oldest deformation D1 is recorded in the N-S-trending Uitkoms cataclasite of pre-Makganyene age (>2.24 Ga) on the ...
