This book was released on 2005 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results from a Quaternary mapping project conducted in two areas of central mainland Nunavut that were located beneath the Keewatin Ice Divide during the last glaciation. Field work included surficial mapping, regional-scale till sampling, stratigraphic studies, and ice-flow indicator surveys. The paper summarizes the findings related to ice flow directions, patterns, and the sequence of flow events in the two map areas. Preliminary interpretations are offered of the ice flow record from the oldest recognized ice-flow events to the most recent flows.

Sandeman and published by Natural Resources Canada. This book was released on 2005 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper provides an overview of the geology of the Darby Lake and Arrowsmith River area, located south-west of Committee Bay, Nunavut. The area is divided into three north-east trending sub-domains, all of which are dominated by granitoid rocks. Characteristic rock types from the area are described along with the phases of regional deformation and metamorphism in the area. Implications of the findings for mineral deposits are briefly discussed.

Download or read book Overview of Quaternary Research for the Committee Bay Project Central Nunavut written by Edward C. Little and published by Natural Resources Canada. This book was released on 2002 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents an overview of the field research conducted during the 2001 season, along with preliminary field observations, from the second year of the Committee Bay Project's Quaternary studies. The objectives of these studies are to compile high-resolution terrain inventories for the Laughland Lake, Walker Lake, Arrowsmith River, and Ellice Hills map areas of central Nunavut; to begin a reconnaissance-scale drift prospecting program that utilizes both heavy-mineral & till geochemical analyses; and to interpret the glacial history at local & regional scales. After introductory sections on regional geology, previous research, and sampling & survey methods, the paper summarizes preliminary results from field observations regarding generalized ice movements & glacial landforms.

This book was released on 2000 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The areas described in this report encompass several northeast-trending Precambrian supracrustal belts set in a granitoid terrane of the Churchill structural province near the base of the Boothia Peninsula, Nunavut. After an introduction on the study area and previous research, descriptions are provided of the area's Archean granitoid complex, Archean and Proterozoic supracrustal rocks, their lithology, contact relations, age & correlation; associated intrusions (pegmatite, diabase dykes); metamorphism; structural geology; and mineral occurrences worthy of further exploration. The appendix contains tables of results of mineral & rock analyses.

This book was released on 1987 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four concrete pads 7.6 m x 7.6 m x 0.5 m thick were constructed in Thailandfor calibration of airborne gamma-ray spectrometers. They comprised a lowradioactivity background pad, a potassium pad, a uranium pad and a thoriumpad. The background pad was constructed of masonry sand and cement, theuranium and thorium pads with a small quantity of uranium and thorium oreadded to the same background matrix, and the potassium pad from feldspar andcement. The uranium ore, from Canada, was in radioactive equilibrium and alow emanator of radon. The thorium ore, a separated monazite beach sand, andthe feldspar were both obtained in Thailand. This report presents a detailed account of calibration pad construction.

Download or read book Canadian Inland Seas written by I.P. Martini and published by Elsevier. This book was released on 2011-09-22 with total page 515 pages. Available in PDF, EPUB and Kindle. 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.
