Geochemical and mineralogical characterization of arsenic in lake sediments impacted by legacy gold mining in the Yellowknife region
Arsenic concentrations in lake sediments in the Yellowknife region, Northwest Territories, Canada are elevated from the weathering of mineralized bedrock and/or from the mining and processing of arsenic (As)-bearing ores ... -
The Geochemical and Mineralogical Controls on the Environmental Mobility of Rare Earth Elements From Tailings, Nechalacho Deposit, Northwest Territories
(2014-05-28)Increased demand for rare earth elements (REEs) for applications in modern technologies has led to an increase in REE exploration. Several deposits are expected to begin mining within a decade, but few studies have examined ... -
Geochemical and Mineralogical Evolution of the McArthur River Zone 4 Unconformity-Related Uranium Ore Body and Application of Iron Oxidation State in Clay Alteration as Indicator of Uranium Mineralization
(2012-11-05)The sandstone-hosted McArthur River Zone 4 U ore body and alteration system, located in the Athabasca Basin, are the focus of a detailed mineralogical and geochemical study aimed at reconstructing its evolution. The ... -
Geochemical Characterization of Coexisting Precipitates and Waters from High-Sulfidation Epithermal Gold Deposits
(2016-02-03)Water management and treatment at closed mine sites have become primary concerns for mining companies due to their costly nature, potential commitment of decades of water treatment, and impact on the environment. The ... -
Geochemical Evaluation of Living and Holocene Brachiopods and the Relationship With Modern Oceanography, Southern Australian Shelf
(2015-10-01)Brachiopod shell chemistry is a commonly used proxy in paleoceanography and paleoclimate studies because their shells are composed of diagenetically-resistant low-Mg calcite and are, for the most part, in chemical equilibrium ... -
Geochemical Indicators of Buried Sulphide Mineralisation Under Sedimentary Cover Near Talbot Lake, Manitoba
(2011-05-16)The Paleoproterozoic Talbot volcanogenic massive sulphide (VMS) Cu-Zn occurrence is located near Talbot Lake, Manitoba, about 80 km south of Snow Lake. The mineralised system is unconformably overlain by more than 100 m ... -
Geologic Controls on Instability in WWI Excavations, Canadian National Memorial Site, Vimy, France
(2008-01-14)The Canadian National Memorial Site, near Vimy, Artois, France, commemorates the WWI Battle of Vimy Ridge; where all four divisions of the young Canadian Corps fought together with the British Forces to liberate the French ... -
Geological models and their influence on geotechnical investigation
(2015-12-02)Geological models, including maps and 3D models, are used in geotechnical site investigation in order to contribute to the evaluation of an area. A geological map is constructed through a complex, subjective interpretation ... -
Geology, Hydrothermal Alteration and Mineralization of the Gold Eagle Deposit: a New Discovery in the Red Lake Camp, Canada
(2012-04-02)Greenstone belts have been recognized as highly prospective settings for high grade gold mineralization, and are host to a number of world class quartz-carbonate vein deposits, which account for approximately 13% of the ... -
