Water and Fine-grained Sediment Assessment in the Capital Region (Edmonton) of the North Saskatchewan River (Canada)
DownloadFall 2022
Purpose: To better understand the behaviors of sediment-associated metals (Cu, Ni, Cd, Mn, Cr, Pb, Fe, Sr, Mo, and Co), an evaluation of physicochemical parameters and metal speciation on suspended and bedload sediment collected from the North Saskatchewan River was conducted in 2018. Sampling...

Precious metal, Lu-Hf, and Re-Os geochemistry of the metasomatized lithospheric mantle: implications for subcrustal precious metal mobilization and MARID petrogenesis
DownloadFall 2022
The connection between metasomatism - the change in chemical composition of a rock via interaction with a fluid or melt - and the formation of metalliferous ore deposits in the Earth’s crust is well established. Similarly, it is now accepted that the Earth’s lithospheric mantle has experienced...

Tracing Organic Contamination from Collection to Curation: Contamination Mitigation of Meteorites and Implications for Advanced Curation Methods of Astromaterials
DownloadFall 2022
Meteorites are the most primitive materials in the solar system and can provide important information about the early earth, planetary processes, and possibly yield insights to the building blocks of life. All meteoritic astromaterials are exposed to both organic compound and microbial...

Tungsten skarn deposits from the Canadian Cordillera: paleogeographic and geochemical controls on ore distribution
DownloadSpring 2022
Tungsten is a critical metal. Critical metals are strategic metals with associated economic, social, energy, geostrategic and environmental issues. As a result, the need to monitor and to secure local supplies of critical elements, including tungsten, has become a strategic priority for many...

The Edmonton-area landscape has been shaped by multiple geomorphic events throughout the Quaternary period. These events account for the distribution of resources and landforms across Central Alberta, making their reconstruction essential to understanding the geomorphic history of the Canadian...

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...

Implications of in situ zircon U-Pb, Lu-Hf, oxygen-isotope, and trace element geochemistry on the petrogenetic history of the northern Hogem batholith in the Quesnel terrane, north-central British Columbia, Canadian Cordillera
DownloadSpring 2022
The Cordilleran orogen of western Canada is a type example of accretionary tectonism and thus an ideal location to study continental growth by oceanic and continental arc magmatism and terrane accretion. Cordilleran Intermontane terranes are interpreted as accreted oceanic arcs that contributed...

Spatiotemporal variability of the fraction of Photosynthetically Active Radiation (fPAR) in a mixed coniferous forest using Wireless sensor networks
DownloadSpring 2022
Contemporary climate change has become rapid, and its impacts affect forest growth and productivity directly and indirectly through changes in temperature, precipitation, carbon dioxide, and other factors. Forest ecosystem plays an essential role in carbon exchange between the atmosphere and...

Cyanobacteria are among the most abundant primary producers in the oceans and are present in nearly every environment on the planet. They were one of the first organisms to evolve nearly 3.8 billion years ago, making them excellent analogs for the investigation of ancient ocean chemistry. The...
