The Prelate area comprises 6,000 square miles in southwestern Saskatchewan adjoining the Alberta boundary north of latitude 50•. Glacial drift which is as thick as 450 feet in two north trending preglacial valleys, overlies shale, sandstone, sands, conglomerates and gravel formations ranging from Late Cretaceous to Early Pleistocene age. Borings and exposures along South Saskatchewan River reveal five till sheets separated by stratified deposits: three till sheets correlate with end moraines within the area. Deposits of several glacial lakes cover much of the area and overlap each other; these lakes discharged successively through spillways to the south, east and north. Dune sand and loess were laid down mainly in post-glacial time. [...]

Missing p.160, 162, 165, 178. / Stratigraphic problems and interpretations of the Cambro-Ordovician rocks of the Quebec complex in an area along the St.Lawrence south shore between the town of Montmagny and St-Andre-de-Kamouraska are outlined and discussed in this thesis. Geologically, the area covers a part of an assemblage of Cambro-Ordovician, pre-Taconic sedimentary rocks which are complexly deformed on the northwestern side of what is believed to be the extension of the Sutton anticlinorium in this part of the northern Appalachian Highlands. [...]

The basal Paleozoic clastic units in the geologic-physiographic area known as the St. Lawrence Lowlands have been examined in the field in varying detail for the past one hundred and twenty years. However, astonishingly little detailed petrologic work has been attempted. The present study is undertaken as a preliminary qualitative evaluation of the basal Paleozoic quartzose sandstones in the St. Lawrence Lowlands of southern Quebec. [...]

The ore deposits of the Noranda camp have been the subject of numerous discussions regarding ore genesis and the relationship of ore to intrusives. [...]

The size distribution of heavy minerals in water-laid sediments has previously been explained in terms of the same fluvial sorting which controlled the grain size of the light minerals. What appeared to be a sympathetic variation between the size of heavy minerals and that of the light mineral with which they were associated led to the formulation of the concept of Hydraulic Equivalence and to belief in the constancy of the hydraulic ratio. [...]

This work was undertaken as a preliminary study of variations in composition of coexisting biotite and muscovite in rocks of metamorphic and plutonic origins. By comparing rocks of two different metamorphic grades, i.e. rocks of the greenschist and amphibolite facies, any observed differences in the distributions of elements between coexisting micas might be related to the pressure temperature conditions at the time of formation. Biotite and muscovite pairs from a granite pegmatite, two granites, and a quartz monzonite were included for comparison in the study. [...]

This thesis is concerned with the taxonomy of a collection of Stromatoporoidea from Baffin Island. Fossils were collected from a great thickness of carbonate strata found at Brodeur Peninsula, the northwestern tip of the island. A detailed review of the Ordovician and Silurian stratigraphy of northwestern Baffin Island is included. A brief statement on the importance of stromatoporoids in stratigraphic correlation is given. [...]

Mount Pleasant in southwestern New Brunswick, the site of an ancient volcano in Mississippian time, is the location of a tin deposit containtng minor amounts of zinc, copper, lead, molybdenum, tungsten, and indium. The country rocks, a gently dipping, highly altered sequence of acidic volcanic rocks, termed feldspar and quartz porphyry, are cut by numerous steeply dipping structures includlng acidic intrusive dikes, breccia dikes and pipes, faults, shears and joints. [...]

Geologists have drawn many conclusions from qualitative and quantitative geological studies in regard to past climatic conditions on the earth. Criteria formulated to determine ancient temperatures, or "paleotemperatures", can be divided into geological, mineralogical and ecological criteria. For example, tillites and pellodites are generally considered as being geological evidence of glacial conditions. [...]

The largest known magnetite deposits in Australia are present in three areas of the Savage River - Rocky River region in northwestern Tasmania. Magnetite is associated with amphibolite or disseminated in meta-sediment. Folded, steeply-dipping Precambrian Whyte Schist underlies most of the region and encloses bodies and concordant linear sheets of amphibolite, which may be genetically related to a Cambrian serpentinized basic and ultrabasic complex.
