Book Description
This report presents findings of a bedrock geological mapping project carried out in 2003 in the Ferguson Lake area, located about 200 kilometres west of Rankin Inlet, Nunavut. The project was initiated to provide better understanding of the geology & deformation history of the area and to put a local nickel-copper-platinum group element deposit into a regional context. The main part of the report describes the rock units exposed in the area (metamorphosed supracrustal rocks and intrusive rocks) and the area's structural elements (gneissosity, folds, foliation, shear zones, faulting). An attempt is then made to correlate the deformational features observed in the area with those documented by other researchers. Finally, implications of the findings for the timing of mineralization are briefly discussed.

Book Description
This paper reports the results of a mapping program in the vicinity of the Boston gold deposit near Hope Bay, south-west Nunavut. It first reviews the regional geology, the granitoid rocks of the Hope Bay volcanic belt, and their contact relationships with the belt. It then focusses on the geology of the deposit area, with descriptions of the rock types, the geologic structures, and the gold mineralization. Finally, implications of the findings for mineralization in other areas of the Hope Bay belt are discussed.

Book Description
"You can't really know the place where you live until you know the shapes and origins of the land around you. To feel truly at home in the Bay Area, read Doris Sloan's intriguing stories of this region's spectacular, quirky landscapes."—Hal Gilliam, author of Weather of the San Francisco Bay Region "This is a fascinating look at some of the world's most complex and engaging geology. I highly recommend this book to anyone interested in an understanding of the beautiful landscape and dynamic geology of the Bay Area."—Mel Erskine, geological consultant "This accessible summary of San Francisco Bay Area geology is particularly timely. We are living in an age where we must deal with our impact on our environment and the impact of the environment on us. Earthquake hazards, and to a lesser extent landslide hazards, are well known, but the public also needs to be aware of other important engineering and environmental impacts and geologic resources. This book will allow Bay Area residents to make more intelligent decisions about the geological issues affecting their lives."—John Wakabayashi, geological consultant

Critical Mineral Resources of the United States
Author: K. J. Schulz
Publisher: Geological Survey
ISBN: 9781411339910
Category : Business & Economics
Languages : en
Pages : 868
Book Description
As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

Category : Fault zones
Languages : en
Pages : 10
Book Description
This paper presents results of geological mapping conducted in 2003 as part of a project addressing the stratigraphic, structural, and metamorphic relationships along the Columbia River valley in British Columbia. The results relate to the stratigraphy of the Upper Arrow Lake & Trout Lake areas and the structural geology of the Columbia River fault zone. The significance of the stratigraphic succession found along Upper Arrow Lake is discussed in regard to previous theories concerning a crustal-scale displacement along the fault zone.

The Magnetotelluric Method
Author: Alan D. Chave
Publisher: Cambridge University Press
ISBN: 1107376971
Category : Science
Languages : en
Pages : 571
Book Description
The magnetotelluric method is a technique for imaging the electrical conductivity and structure of the Earth, from the near surface down to the 410 km transition zone and beyond. This book forms the first comprehensive overview of magnetotellurics, from the salient physics and its mathematical representation to practical implementation in the field, data processing, modeling and geological interpretation. Electromagnetic induction in 1-D, 2-D and 3-D media is explored, building from first principles, and with thorough coverage of the practical techniques of time series processing, distortion, numerical modeling and inversion. The fundamental principles are illustrated with a series of case histories describing geological applications. Technical issues, instrumentation and field practices are described for both land and marine surveys. This book provides a rigorous introduction to magnetotellurics for academic researchers and advanced students, and will be of interest to industrial practitioners and geoscientists wanting to incorporate rock conductivity into their interpretations.
