A Model for the Solubility of Minerals in Saline Aqueous Fluids in the Crust and Upper Mantle
DownloadFall 2018
Quantifying and predicting the dissolution of minerals in complex (multicomponent) aqueous fluids across wide ranges of P-T space is critical for interpreting geologic processes that involve water-rock interactions in the Earth’s crust and upper mantle. Here, we define a new thermodynamic model...

Controls on Solubility and Deposition of Quartz, Calcite, Fluorite and Anhydrite in Boiling Saline Hydrothermal Systems
DownloadSpring 2022
Fluid boiling is a key mechanism for precipitation of minerals in epithermal deposits, and evidence for boiling includes a variety of vein mineral textures that indicate rapid deposition. Hence, the relationships between vein mineral paragenesis and boiling are critical to interpreting processes...

Fluid Evolution and Mineralization of Two Distinct High-Sulfidation Epithermal Occurrences in the Toodoggone District, British Columbia, Canada
DownloadSpring 2024
At the Toodoggone District of northern British Columbia, the Ranch area and the Silver Pond zone within the Lawyers area represent two distinct high-sulfidation epithermal occurrences that show some broad similarities but many significant differences. Similarities include some overlaps in terms...

Fall 2020
The physical and chemical properties of aqueous fluids and melts, and how these evolve through time and space, are key controlling factors that govern the formation of mineral deposits. For some metal-rich system types such as iron oxide-apatite deposits (IOA), the sources and chemical...
