Thermodynamics of geologic fluids
Fluids play a vital role in essentially all geologic environments and processes, and are the principal media of heat and mass transfer in the Earth. The properties of geologic fluids can be diverse, as fluids occur at conditions ranging from ambient temperatures and pressures at Earth's surface, to …

Geologic and Economic Aspects of Lake Agassiz Clays
<p>This thesis discusses the geologic background and explores the properties and economic aspects of the clays of Lake Agassiz. The lake was located in the present Red River Valley, a leading farming area. The first complete study of the area was made by Warren Upham in the 1890’s. </p><p>Lake …

Geologic Setting of the Phoenix Lander Mission Landing Site
<p>The Phoenix Lander touched down on the northern distal flank of the shield volcano Alba Patera in a ~150 km wide valley underlain by the Scandia Formation. The geomorphology and geology of the landing site is dominated by the ~0.6 Ga, 11.5 km wide, bowl-shaped impact crater, Heimdal, and its …

The subsurface fluid mechanics of geologic carbon dioxide storage
… at power plants and then injected into deep geologic reservoirs for long-term storage. While CCS may be critical for the continued use of fossil fuels in a carbon-constrained world, the subsurface behavior of CO₂ remains poorly understood, which has contributed to the absence of government …

Implications of permeability uncertainty within engineered geologic fluid systems
Carbon-capture and sequestration (CCS) in geologic reservoirs is one strategy for reducing anthropogenic CO2 emissions from large-scale point source emitters. Recent developments have shown that basalt reservoirs are highly effective for permanent mineral trapping on the basis of CO2-water-rock …

The experimental investigation of the inelastic behavior of geologic materials
A knowledge of the mechanical behavior of geologic materials (rocks and minerals) has become increasingly important in mining and civil engineering, geology, geophysics and more recently in a number of defense and aerospace fields. This research describes an investigation of one particular aspect …

A nonlinear viscoplastic double yield surface constitutive model for geologic materials
A new constitutive model is proposed to describe the stress-strain-time behaviour of clays and organic soils. This approach is based on the framework of overstress viscoplastic theory and can be applied to any elastoplastic (inviscid) model.The most innovative idea of the proposed model is the …
