Book excerpt: The map area is located east of Long Lake and comprises Daley Township and the eastern part of Ginoogaming First Nation Indian Reserve, formerly Long Lake Indian Reserve 77. Field work was carried out in summer 1988 and consisted of mapping the Precambrian bedrock and its mineral deposits. Rock samples were collected in the field, with 50 samples submitted for gold and silver assays, 40 for whole-rock geochemistry, and 88 for thin sectioning. This report describes the general geology, rock geochemistry, structural geology, metamorphism and alteration, geochronology, and economic geology of the area, including descriptions of existing properties, and the possibilities for gold, silver, base metals, iron, corundum, stone, and sand and gravel.

This book was released on 2000 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines aspects of the geological evolution of the Sharbot Lake domain and compares it with that of neighbouring domains & terranes in the Central metasedimentary belt, Grenville Province, Ontario. The study reports uranium-lead zircon & titanite geochronological ages for a granodiorite phase of the Pakenham intrusion from the northern part of the Sharbot Lake domain. The new data expand the known range of magmatism in this part of the belt, elucidate the early tectonic evolution of the domain, and constrain the timing of overprinting metamorphism. Possible links between the Pakenham structure and the Wolf Grove structure to the south-east are also discussed.

This book was released on 2000 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North Caribou terrane is one of the largest blocks with continental affinities in the western Superior Province. This paper reviews field relationships at the southern margin of this terrane in the western Uchi belt between Trout Lake, north-west Ontario, and Lake Winnipeg, Manitoba. After an introduction on the regional geological framework, the paper describes the Trout Lake Batholith, the Red Lake-Garner Lake lobe, the Bloodvein-Wanipigow River corridor, the English Lake magmatic complex, and the eastern Lake Winnipeg area. Implications of the observations for crustal architecture are discussed.

This book was released on 2000 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents geochronological age determinations of zircons from eight plutons in the Grenville Province, Ontario (Oso and Mountain Grove plutons in the Sharbot Lake domain; Silver Lake & Bennett Bay plutons and Fall River mangeritic augen gneiss associated with the Maberly shear zone; North Crosby & Pike Lake plutons in the north-west sheared part of the Frontenac terrane; and the Beales Mills pluton in the interior of the Frontenac terrane). The results are used to propose a re-interpretation of the tectonics of the Frontenac suite and the origin of the magmas responsible.

Book excerpt: The various chapters of this book have been written by researchers who are still working in the Canadian Inland Seas region. The chapters synthesize what is known about these seas, yet much still is to be learnt. It is hoped that this collection of information will serve as a springboard for future, much needed, studies in this fascinating, diverse region, and will stimulate comparative analyses with other subarctic and arctic basins of the world. The Canadian Inland Seas are the only remnants, albeit cold, of the ancient cratonic marine basins which occupied central North America throughout the Paleozoic and part of the Mesozoic. Precambrian rocks and gently dipping Paleozoic sedimentary rocks underlie the seas. The area is also close to the centers of Pleistocene glaciations. The coastal areas represent an emerged landscape of the post-glacial Tyrrell sea, as the region has been isostatically uplifted to about 350 meters since glacial times. A total of 56 fish species inhabit Hudson Bay and James Bay. Seals, whales and one of the largest and southernmost populations of polar bears inhabit the seas as well. The coastal areas are important habitats for migratory bird populations, some of which migrate from as far away as Southern Argentina.The ostic environment has preserved these regions relatively unchanged by man, with only a major harbour at Churchill, Manitoba, which is active for part of the year, and a second large, rail-terminal settlement in the south at Moosonee, Ontario. A few, small, native Indian and Inuit villages dot the coasts. The seas are being affected indirectly by the damming of rivers for the generation of hydroelectric power, and by drainage diversions towards the man-made reservoirs. A major project is being completed in Quebec east of James Bay, but other rivers in Ontario and Manitoba have been dammed as well. Undoubtedly freshwater is one of the more important resources of the area, however its exploitation needs careful thought because of the possible long-range effects on the environment, particularly the coastal marshes, which sustain much of the eastern American intercontinental migratory avifauna. Other resources occur in the regions, primarily minerals and perhaps petroleum. For the most part however, such resources remain to be discovered.

Book excerpt: Presents a geochronological and geochemical study of the Barbers Lake and McLean plutons in the Grenville Province of Ontario, including comparisons of whole-rock analyses of these plutons with the Elphin and Leggat Lake plutons. The assignment of various plutons in the study area to one of several age groups is discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The early chapters of the volume present data and interpretations of the geophysics of the craton and summarise, with sequential maps, the tectonic evolution of the craton. The main body of the text and accompanying plates and figures present the stratigraphy, structural history, and economic geology of specific sedimentary basins and regions. The volume concludes with a summary chapter in which the currently popular theories of cratonal tectonics are discussed and the unresolved questions are identified.
