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 ...

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) ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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, ...
