Download or read book Regional Studies written by Bozzano G Luisa and published by Elsevier. This book was released on 2012-12-02 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regional Studies is a collection of papers that deals with strata-bound mineral deposits in the Eastern Alps, in the Canadian Cordillera, in north-central, and southwest England. Other papers describe southern African stratiform ore deposits and the genesis of Irish base-metal deposits. One paper compares the various types of volcanogenic mineral deposits and their depositional environments characterized by distinct assemblages of volcanic rocks, which formed in the Northern Appalachians during certain episodes of the tectonic evolution. The paper notes that the youngest volcanogenic deposits of economic interest are tungsten—molybdenum—tin—bismuth base metal deposits in highly altered rhyolitic sub-volcanic complexes at Mount Pleasant, New Brunswick. Another paper reviews the mineral occurrences in southern Africa that include stratiform, non-magmatic, ore deposits, The paper considers a subdivision of deposits formed from surficial chemical processes during previous (or current) cycles of weathering and erosion. Many ore bodies have a dual origin: for example, the iron in the high-grade hematite deposits is partly syngenetic and partly epigenetic. The paper also illustrates the time-dependence of some stratiform ore deposits in southern Africa in a schematic diagram. Geologists, researchers, or engineers whose works are related with ore deposits and mining will benefit tremendously from the collection.

Download or read book Basement Tectonics 8 written by Mervin J. Bartholomew and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 729 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 8th International Conference on Basement Tectonics was held in Butte, Montana, August 8-12,1988. Historically, basement tectonics conferences have focused on such topics as reactivation of faults, the influence of basement faults on metallogeny and hyrocarbon accumulation, and the use of geophysical and remote sensing techniques to interpret subsurface and surface geology. The 8th Conference diverged from past conferences in that a unifying theme was selected. Because ancient major terrane or cratonic boundaries are often postulated to be fault zones which are subsequently reactivated, the conference was organized to examine all aspects of ancient continental margins and terrane boundaries and to compare younger (Mesozoic) ones, about which more is known, with older (Paleozoic and Precambrian) ones. Moreover, because the 8th Conference was held in the northwestern United States, a greater emphasis was placed on the Mesozoic margin of western North America and the North American shield. The seven oral sessions and four poster sessions all dealt with aspects of the conference theme: characterization and comparison of ancient continental margins. The organizers extend their thanks to those individuals who graciously consented to serve as moderators for the oral sessions: John M. Bartley, Mark S. Gettings, M. Charles Gilbert, John M. Guilbert, Donald W. Hyndman, William P. Leeman, Robert Mason, and A. Krishna Sinha. The program with abstracts volume was prepared by S. E. Lewis and M. J. Bartholomew.

Download or read book Compressional Tectonics written by Elizabeth J. Catlos and published by John Wiley & Sons. This book was released on 2023-06-14 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: A synthesis of current knowledge on collisional and convergent plate boundaries worldwide Major mountain belts on Earth, such as the Alps, Himalayas, and Appalachians, have been built by compressional tectonic processes during continent-continent and arc-continent collisions. Understanding their formation and evolution is important because of the hazards associated with convergent and collisional plate boundaries, and because these mountain belts contain resources such as precious metals, rare earth elements, oil, gas, and coal. Compressional Tectonics: Plate Convergence to Mountain Building reviews our present-day knowledge of the tectonic evolution of the Alpine-Himalayan and Appalachian belts. Volume highlights include: overview of terminology relating to compressional and contractional tectonics discussion of subduction zone dynamics debates over the timing of the collision and convergence of particular subduction and suture zones examples of the different stages in the development of orogenic belts This book is one of a set of three Tectonic Processes: A Global View The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Download or read book The Regulation of Peace River written by Michael Church and published by John Wiley & Sons. This book was released on 2014-12-31 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview of the first longitudinal study of the downstream response of a major river to the establishment of a large hydropower facility and dams. Peace River, a northward flowing boreal river in northwestern Canada was dammed in 1967 and the book describes the morphological response of the 1200 km downstream channel and the response of riparian vegetation to the change in flow regime over the first forty years of regulated flows. Beginning with a description of the effect of regulation on the flow and sediment regimes of the river, the book proceeds to study changes in downstream channel geometry on the main stem, on the lowermost course of tributaries, and on the hydraulic geometry, the overall morphology of the channel, and riparian vegetation succession. The river is subject to annual freeze-up and break-up, so a chapter is devoted to the ice regime of the river. A chapter compares the effects of two extraordinary post-regulation flood events. The penultimate chapter presents a prediction of the ultimate equilibrium form of the regulated river based on rational regime theory. An online database of all the main observations will provide invaluable material for advanced students of river hydraulics and geomorphology. This book carefully brings together a range of studies that have been previously inaccessible providing a rare and comprehensive analysis of the effects of a big dam on a river, a river that itself represents an example of the kind of system that is likely to receive considerable attention in the future from dam engineers and environmentalists. • An invaluable reference to river scientists, hydroelectric power developers, engineers and environmentalists • Focus on a northward flowing boreal river, a type that holds most of the remaining hydroelectric power potential in the Northern Hemisphere • Exceptional separation of water and sediment sources, permitting study of the isolated effect of manipulating one of the two major governing conditions of river processes and form • Unique example of water regulation and both natural and engineered flood flows • Detailed study of both morphological changes of the channel and of the riparian vegetation • Online data supplement including major data tables and numerous maps. Details of the main observations and provides material for problem study by advanced students of river hydraulics and geomorphology are provided

Book excerpt: The purpose of this study is to examine & characterize facies changes in the Devonian strata of north-eastern British Columbia, particularly within the economically important Dunedin Formation, and to correlate these rocks with correlative strata in the subsurface to the east. Preliminary observations & interpretations based on field work are discussed with regard to general stratigraphy, sedimentary features, and regional facies development of the Dunedin Formation.
