Available in PDF, EPUB and Kindle. Book excerpt: The motivation for this volume came from the idea that thePrecambrian is the key, both to the present, and to theunderstanding of the Earth as a whole. The Precambrian constitutesabout 85% of Earth's history, and of that, about 3.75 billion yearsof Precambrian time, represented by rocks, are accessible togeoscientists. Ancient atmospheric and environmental conditions canbe traced back to the time when the Earth was only about 250million years old. Precambrian rocks supply almost 75% of importantmineral resources such as Fe, Mn, Au, Pt and Cr. Many of theseelements are associated with sedimentary rocks and some importanthydrocarbon, coal and graphite deposits are also hosted byPrecambrian rocks. This volume is aimed at geoscientists interested in Precambriansedimentary rocks and at students of Earth history. It containsreview articles discussing Precambrian conditions and case studiesfrom Precambrian shields and successions of North and SouthAmerica, Australia, Africa, Europe, Asia and India. Theintroductory papers, written by experts on Precambrianenvironments, treat comprehensively the application of actualism tothe Precambrian, the evolution and influence of life on thesedimentary rock record, the genesis of Banded Iron Formations, thePrecambrian sulphur cycle and the significance of Precambrianchemical carbonate precipitates. The case studies includedepositional settings and processes in Archean terranes, inPaleoproterozoic sequences, with some emphasis on the lack ofvegetation and weathering, and in late Proterozoic sequences, withsome emphasis on glacial deposits. The contributions demonstratethat Precambrian sedimentary deposits are commonly similar to theirPhanerozoic counterparts in terms of composition, sedimentaryprocesses, and depositional setting, but may differ significantlyas a result of lack of vegetation, climatic and biologicalconstraints, composition and circulation of seawater, and thesecular involvement of continental crust.

This book was released on 1984 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report contains a detailed description of the unconsolidated sedimentary materials and landforms in the Smithers-Terrace-Prince Rupert region, and an account of the geological processes that have been active in shaping this area during late Quaternary time. The information in this report is vital to an understanding of the character and distribution of agriculatural soils, the nature of foundation conditions, the location and extent of construction aggregate and aquifers, and the nature of natural hazards in the region.

Book excerpt: THis volume consists of papers presented to the symposium 'Metamorphism in the Canadian Shield', which was held in Ottawa, May 5-6, 1977, to mark the completion of the first metamorphic map of the Canadian Shield. The papers provided the regional contributors to the map project an opportunity to discuss the outstanding metamorphic features in their regions and also to place on record information too detailed to be shown on the map.

Download or read book Precambrian Geology of the Arseno Lake Map Area District of Mackenzie Northwest Territories written by R. A. Frith and published by . This book was released on 1991 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the course of regional mapping of the Indin Lake area, a number of gneiss domes were discovered just west of Arseno Lake. Further study of the domes led to remapping at a 1:50,000 scale, an analysis of the structure of the domes in detail and a study of metamorphic assemblages present in the paragneiss of the region being conducted using microprobe techniques. This report summarizes the work to date, including older structural studies along the Slave Province boundary. The regional tectonism is reinterpreted in light of the more recent ideas brought forward by mapping the Wopmay Orogen.
