Effects of Hurricane Fault Architecture on Groundwater Flow in the Timpoweap Canyon of Southwestern, Utah
<p>Hydrogeologically important features of fault zones include undamaged country rock, the damage zone, and the core zone. Fault cores generally have low porosity and permeability, and often act as a barrier to groundwater flow. The damage zone, by contrast, consists of small faults and fracture …

The initiation and evolution of ignimbrite faults, Gran Canaria, Spain
Understanding how faults initiate and fault architecture evolves is central to predicting bulk fault zone properties such as fault zone permeability and mechanical strength. The study of faults at the Earth’s surface and at near-surface levels is significant for the development of high level …

Faults as episodic conduits for hydrocarbons, CO2 and groundwater in sandstones
… porous media. In particular, predicting complex fault architecture at depth, currently relies on deterministic algorithms, that do not take account of these dynamic coupling. For instance, creation of permeability due to fracturing may permit fluid flow to enter a fault zone, resulting in …

Numerical Modeling of Geologic Carbon Dioxide Storage in Faulted Siliciclastic Settings
… Thesis focuses on geologic CO₂ storage (GCS) in faulted siliciclastic sedimentary basins, and addresses the impact of uncertainty sources on forecasts of CO₂ migration made with physics-based numerical models. A key contribution of this work is the quantification of uncertainty on fault …

Fluid-rock interactions in a carbon storage site analogue, Green River, Utah
… or facilitate leakage by corroding cap rocks and fault seals. Modelling the progress of such reactions is frustrated by uncertainties in the absolute mineral surface reaction rates and the significance of other rate limiting steps in natural systems. This study uses the chemical evolution of …

The structural architecture of seismogenic faults, Sierra Nevada, California; implications for earthquake rupture processes
Earthquake ruptures along tectonically active faults nucleate predominantly at depths of 5 to 12km in the crust, so the portions of faults that slip in these events cannot be directly observed. The geometry and composition of seismogenic faults controls the nucleation, propagation and termination …

Combined structural and magnetotelluric investigation across the West Fault Zone in northern Chile
… Untersuchung eines Segmentes der 'West Fault'-Störung in den nordchilenischen Anden. Die West Fault ist ein Abschnitt des über 2000 km langen Präkordilleren-Störungssystem, welches im Zusammenhang mit der Subduktion vor der südamerikanischen Westküste entstanden ist. Die Aktivität dieses …
