Fall 2013
Monocrystalline gem-quality diamonds from Akwatia, Ghana and De Beers Pool, South Africa have trace-element concentrations ranging from ppt to ppm levels, but mostly are below the limit of quantification. CeN/EuN (1–6; N = chondrite normalized) and CeN/TiN (0.6 to 12) indicate mildly elevated...

Expression of Major and Trace Element Signatures of the Frasnian Duvernay Formation within a Sea Level Context: insights into the processes that control mudstone composition, paleoredox conditions and organic matter enrichment
DownloadSpring 2016
This study evaluates the effects of sea level on redox conditions, shale composition and sediment provenance in the Late Devonian (Frasnian) Duvernay Formation of the Western Canada Sedimentary Basin (WCSB) of Alberta, Canada, an organic-rich ‘black’ shale localized between the reefs and...

Spatial variations of total and dissolved trace elements and their distributions amongst major colloidal forms along and across the Lower Athabasca River
DownloadFall 2020
The Athabasca River (AR) is the longest river in Alberta with a wide variety of natural and potential anthropogenic inputs. The purpose of this study was to quantify the spatial variation of trace element (TE) concentrations and forms in this aquatic system. Water samples were gathered along a...

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...

Trace elements associated with the coarse and fine aerosol fractions in Sphagnum moss within the Athabasca Bituminous Sands region
DownloadFall 2022
The Athabasca Bituminous Sands industry in Alberta has dramatic impacts on the economy of the province. Nevertheless, with increasing industrial operations, environmental concerns are also raised regarding the contamination of air and water with trace elements (TEs). To better assess the...
