Available in PDF, EPUB and Kindle. Book excerpt: Proterozoic time produced much of great interest to geologists, and was of tremendous economic import to the people of Canada and the United States. Most of the iron deposits of the Lake Superior district, the Michigan copper deposits, the enormously important Sudbury nickel-copper-platinum deposits, the spectacular silver deposits of the Cobalt district, and all of the important uranium ores in the Shield area are considered to have formed during this period in geological time. Proterozoic rock groups include those Precambrian rocks which are least deformed and metamorphosed. Because of their important economic deposits, they have been examined in great detail in certain localities. The results of such examination, and of others which were for reconnaissance only, are summarized in this volume of the Royal Society of Canada. Suggestions are made for revision of previous interpretations of Precambrian history, and the terminology which grew out of them. Three papers deal with problems arising from the current use of the term Proterozoic, and with possible changes in its use to bring it more into accord with the facts.

Book excerpt: This is a discount Black and white version. Some images may be unclear, please see BCCampus website for the digital version.This book was born out of a 2014 meeting of earth science educators representing most of the universities and colleges in British Columbia, and nurtured by a widely shared frustration that many students are not thriving in courses because textbooks have become too expensive for them to buy. But the real inspiration comes from a fascination for the spectacular geology of western Canada and the many decades that the author spent exploring this region along with colleagues, students, family, and friends. My goal has been to provide an accessible and comprehensive guide to the important topics of geology, richly illustrated with examples from western Canada. Although this text is intended to complement a typical first-year course in physical geology, its contents could be applied to numerous other related courses.

Download or read book Proterozoic Redbed Sequences of Canada written by Francis W. Chandler and published by Geological Survey of Canada. This book was released on 1980 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Redbeds are clastic sedimentary rocks stained red by hematite. They offer important information concerning past climates and depositional and tectonic environments, their paleomagnetic properties and in the reconstruction of past plate motions, and -- possibly of greatest significance -- deposits of base metals, uranium and vanadium occur closely associated with redbeds in many parts of the world. By bringing together information on redbeds the Geological Survey is providing a tool useful in mineral exploration and is thereby meeting one of its principal objectives -- determining the mineral and energy resources available to Canada." --
