Clay minerals are ubiquitous at the Earth’s surface and they impart a significant influence on numerous geochemical cycles due to their high surface reactivity. Aqueous pH and ionic strength (hereafter IS) are two major factors that affect clay surface reactivity and subsequently govern trace...

Hydrothermal Treatment of Bitumen Froth at 250 °C: Impact on Bitumen Properties and Role of Clay Minerals
DownloadFall 2023
Bitumen froth produced in the hot water extraction process of mined oil sands consists of about 60 wt % bitumen, 30 wt% water and 10 wt% mineral solids. To convert the bitumen in bitumen froth into a marketable product, the water and solids need to be separated. Solvent-based froth treatment...

Trace Element Variability in Clay Sediments as a Function of Environmental Conditions within the Fluvial to Marine Water Transition Zone
DownloadFall 2019
Estuaries are marginal marine environments of considerable complexity, due to their spatial and temporal variations in hydrodynamic energy, water chemistry, and sediment source and composition. This complexity hinders geologists’ ability to accurately reconstruct paleoenvironments and...
