Leakage and swell in emulsion liquid membranes : experimental studies and corrected computational methods
Emulsion liquid membrane (ELM) systems are water-in-oil emulsions dispersed in water, which, with appropriate chemistry, can efficiently extract and concentrate metals (e.g., cadmium, chromium, copper, cobalt, nickel, ... -
Alteration and mineral paragenesis of the McArthur River and Fox Lake uranium deposits, Athabasca Basin : a new model for the formation of unconformity-related uranium deposits
The McArthur River uranium mine in the Athabasca Basin, Canada, hosts the largest high-grade uranium deposit in the world, accounting for 12% of global uranium production in 2015. McArthur River is a Proterozoic ... -
Depositional and chemical controls on sedimentation, sequence stratigraphy, and pore development of the Pronghorn, Lower Silt, and Lower Shale members of the Bakken Formation, Williston Basin
An integrated stratigraphical, petrographical, geochemical, and petrophysical analyses were presented in this study to characterize the depositional environments, stratigraphic framework, and pore network of the Upper ... -
Structural-metallogenic evolution of the Garrison gold camp of the Archean southern Abitibi greenstone belt, Ontario, Canada
The southern Abitibi greenstone belt in Ontario and Quebec, Canada, stands out as the most prolific fragment of Neoarchean crust within the Superior province. Over 200 Moz gold endowment is attributed to numerous orogenic ... -
Form and fill of a transtensional rift basin : lower Talangakar Formation, Jatibarang subbasin, offshore NW Java, Indonesia
The Paleogene synrift sediments in North West Java Basin area are viable and prolific petroleum plays and the exploration of the reservoir within these lacustrine strata likely be a source of future reserve additions, ... -
Geologic significance of microbialites and microbially influenced sedimentary structures of the Bakken Formation, Williston Basin, North Dakota
The Late Devonian – Early Mississippian Bakken Formation, is a prolific petroleum system that is currently producing more than 1.4 million barrels of oil per day (NDDMR, 2019). Advances in horizontal drilling and hydraulic ... -
Three essays on mineral economics and economic geography
This dissertation presents three essays on resource economics. The first essay discusses economics of mineral supply as a by-product. Specifically, this essay estimates how much uranium might be recoverable from current ... -
Elastic waveform inversion of microseismic data in anisotropic media
Event location, estimation of source mechanisms, and anisotropic velocity model-building are the most important goals of microseismic monitoring of hydraulic fracturing. Waveform inversion (WI) could provide higher-resolution, ... -
Progradational slope architecture and sediment partitioning in the mixed siliciclastic-carbonate Bone Spring Formation, Permian Basin, west Texas
Slope-building processes and sediment partitioning in mixed carbonate-siliciclastic sediment routing systems are poorly understood but are important constraints on the spatial and temporal distribution of reservoir-forming ... -
Evidence for a subseafloor replacement origin of the Cretaceous Palma volcanogenic massive sulfide deposit, central Peru
The Palma volcanogenic massive sulfide deposit is one of the most recent significant base metal discoveries in central Peru. Base-metal mineralization can be followed over a strike length of over 2.5 km, with the currently ... -
Nature and timing of metamorphism within the San Isabel granite aureole, Wet Mountains, south Colorado , The
The Wet Mountains, southern Colorado, expose Mesoproterozoic metamorphic and magmatic rocks that record the early deformational history of the east-central continental USA. An increase in metamorphic grade from northwest ... -
Characterization of pentlandite-bearing quartz veins of Kambalda, Western Australia
The Kambalda Dome of the Yilgarn Craton is located in Western Australia and has been historically mined for Ni after the discovery of magmatic sulfide orebodies in 1966. The Ni orebodies consist of komatiite-associated ... -
Hybrid nanoscale devices for magnetocaloric refrigeration
Refrigeration is one of the main technologies contributing to climate change because of its use of greenhouse gases. Magnetic cooling provides an alternative refrigeration method that is more energy efficient than standard ... -
Seismic inversion for the Vaca Muerta shale of the Neuquen Basin, Argentina
The Vaca Muerta Shale in the Neuquen Basin of Argentina is a world class shale reservoir still in the early stages of development. With thickness of 500 m, TOC of up to 14% and estimated recoverable reserves of 16 billion ... -
Learning and online prediction of weld quality in robotic GMAW
We have come a long way in the automation of robotic welding. But with the decline in qualified welders, there has been a steadily growing demand for robotic solutions with capabilities that match that of human welders. ... -
Effects of conductive well casings on electromagnetic surveys : experimental studies and numerical modelling, The
Controlled source electromagnetic (CSEM) surveys can be used in petroleum exploration to supplement seismic reflection data because electrical resistivity is highly sensitive to pore space fluid content. Traditionally, ... -
Pre-Laramide salt tectonics in the Eagle Basin : a new paradigm for the tectonic evolution of central Colorado
Combined field mapping, measured stratigraphic sections, and balanced cross-sections of the Pennsylvanian-aged Eagle Valley Evaporite and overlying Late Pennsylvanian- to Jurassic-aged strata indicate a long-lived phase ... -
Enhanced geothermal system (EGS) well stimulation design and simulation using DFN-based model : Newberry EGS case study
A conceptual model of the Newberry EGS (Enhanced Geothermal System) project stimulation program for well NWG 55-29 has been developed. A discrete fracture network (DFN) model is embedded in the simulation to investigate ... -
Estimating geoelectric fields for geoelectric hazard assessment : an examination of data and models within complex physiographic zones
During magnetic storms, time-varying geomagnetic fields induce geoelectric fields at the surface that produce geomagnetically induced currents (GICs) within power transmission systems. These GICs can permanently damage ... -
Benchmarking isosopin symmetry breaking in ab initio nuclear theory via the isobaric multiplet mass equation in T = 1 superallowed β decay systems
Searching for physics Beyond the Standard Model (BSM) has become a central focus in physics research over the past few decades. One way to do this is through precision measurements of superallowed 0+ → 0+ Fermi β decay. ...
