Pliocene climate change on Ellesmere Island, Canada : annual variability determined from stable isotopes of fossil wood
(2006-06-06)
Tree-ring analyses have contributed significantly to investigations of climate change and climate cycles, including the North Atlantic Oscillation (NAO), Pacific Decadal Oscillation (PDO) and El Niño/Southern Oscillation ...
Re-Os dating of algal laminites : reduction-enrichment of metals in the sedimentary environment and evidence for new geoporphyrins
(2004)
The principal aim of this study is the evaluation of algal laminites as appropriate substrates for the application of the Re-Os chronometer. Devonian Keg River algal laminites produced an isochron date (382.2 ± 6.9 Ma) ...
Sedimentary depositional environment of the Prairie Evaporite Formation, Saskatoon region, Saskatchewan
(1990-08-01)
This thesis attempts to reconstruct the environments in which the potashbearing,
Prairie Evaporite Formation (Middle Devonian) of the Elk Point Basin was
deposited, using preserved primary sedimentary features. Evidence ...
Trace element and sulphur isotope geochemistry of sulphide deposits from the Flin Flon and Snow Lake areas of Saskatchewan and Manitoba
(1972)
The Precambrian massive sulphide deposits of the Flin Flon and Snow Lake areas of Saskatchewan and Manitoba have been classified into a "barren" group, containing dominantly pyrrhotite and/or pyrite or arsenopyrite with ...
Trace element geochemistry of the Milk River aquifer groundwater, Alberta, Canada
(1998)
Groundwater samples from 27 wells located along a 50 km flow path in the Milk River
aquifer, Alberta, Canada, were analyzed for trace elements including rare earth elements
(REEs). The objectives were to: 1) complete the ...
Biotransformation of selenium and arsenic in insects : environmental implications
(2009-07-09)
Living organisms constantly respond to changing environmental conditions, and some changes can be far from optimal for many organisms. Insects represent the majority of species in many ecosystems and play an important role ...
Structure-function relationships in cellular copper control
(2009)
X-ray absorption spectroscopy and computational chemistry have been used to probe the structure of biomolecules involved in cellular copper homeostasis. X-ray absorption spectroscopy shows that copper chaperones involved ...
Groundwater investigation in the vicinity of Morden, Manitoba
(1968)
During the summer of 1967, an investigation of the areal
ground-water conditions in the vicinity of Morden, Manitoba,
was carried out. The study was prompted by concern about
deteriorating and dying vegetation on the Canada ...
Thermo-tectonic history of the Kisseynew Domain near Sandy Narrows, Saskatchewan
(2001)
The Sandy Narrows study area is comprised of mainly 1.86-1.84 Ga Kisseynew Domain marine metaturbidite rocks which represent the uppermost stratigraphic level in the Reindeer Zone. Based on mineralogical changes from west ...
Mineralogy, geochemistry and petrology of the Catherwood and Kinley Saskatchewan meteorites
(1973)
Separate aspects of the mineralogy, geochemistry and petrology of the Catherwood and Kinley Saskatchewan meteorites were investigated in this study.
Since Catherwood and Kinley were found approximately twelve miles apart, ...
