The study assesses process-morphology relationships on 27 debris slopes of an Arctic periglacial environment. A systematic sampling procedure is followed to obtain profile angle and debris size, shape and orientation for each slope. A rigorous test design to analyze size and shape variation has high statistical power and yields reliable results. Vector analysis is employed in the study of debris orientations, while non-parametric tests are performed on geometric parameters. Supplementary studies are made on rockfall accumulation and subsurface meltwater flow. Responses of slope geometry and debris characteristics to three major process groups are independently analyzed and compared in four selected localities, and the nature and effects of each process in the study area are presented. A discussion of interactions between the processes, geometry and debris concludes with a relative assessment of each process. / Thesis / Master of Science (MS)

<p> Separated minerals From 18 different rock samples were available. These came From various locations in the Grenville province. OF these samples, there were 44 minerals which had at least one coexisting mineral phase. These were all analysed For boron by thermal neutron irradiation using the Prompt Gamma Neutron Activation Analysis at McMaster University Nuclear Reactor. There was a preferential boron partition determined For the samples originating From an igneous source, and a numerical value of 0.7 was determined for k-Feldspar/Biotite. There was no Preferential boron partition among the coexisting phases that originated From a metamorphic source. Sphene and Fluorite contained much less boron than other minerals that coexisted with them. </p> / Thesis / Bachelor of Science (BSc)

The purpose of this thesis is to establish possible changes in the CI/Br ratio of ancient oceans over the past 2 x 10 9 years. Variations in the Cl/Br ratio of carbonate rocks are used to indicate these changes. A secondary objective of this thesis is to determine the distribution patterns of F in limestones and dolomites. Variations in the F content of dolomites are shown to be related to environment of deposition and can be used to establish tho genesis of dolomite. The contents of the thesis include; 1) a comprehensive review of the pertinent literature, 2) a discussion of the evolution of the Cl/Br ratio of the ocean. 3) application of F in paleoenvironmental reconstruction, and 4) suggestions for further research. / Thesis / Doctor of Philosophy (PhD)
