Book excerpt: The Early Proterozoic Michigamme Formation of northern Michigan was deposited in the southeastern part of the Animikie basin. The formation conformably overlies the Goodrich Quartzite and comprises three widespread members a lower member of thin-bedded shale, siltstone, and sandstone; the Bijiki Iron-formation Member; and an upper member of tur- biditic graywacke, siltstone, and mudstone and a few local members. The Goodrich Quartzite is interpreted as having been deposited in a tidally influenced shallow marine environ- ment. The lower member of the Michigamme is interpreted as having been deposited in a tidally influenced environment, the iron-formation member as having been deposited below wave base in somewhat deeper water, and the upper member as having been deposited in still deeper water with turbidity currents being a major depositional mechanism. Several lines of evidence including paleocurrents, paleo- geographic setting, and neodymium isotopes suggest that the graywacke of the southern part of the outcrop area was derived from the south (Early Proterozoic Wisconsin magmatic terranes, Archean miniplates, and older Early Proterozoic sedimentary units formed on the continental margin), and that the graywacke in the northern area was derived from an Archean terrane to the north. The tectonic model that best fits the available data is a northward-migrating foreland basin.

Book excerpt: Sm-Nd survey of Precambrian granitic and metasedimentary rocks collected from several geophysically defined blocks in central Minnesota confirms the presence of some fundamental geologic boundaries previously mapped on the basis of structure. The Malmo discontinuity an Early Proterozoic structure separates the Archean Minnesota River Valley ter- ranes from an Early Proterozoic (Penokean magmatic) terrane and the McGrath Gneiss dome of east-central Minnesota North of this boundary, the Penokean fold-and-thrust belt can be divided into fault-bounded terranes that were assembled during the Penokean orogeny. Each terrane within the study area has distinct crust formation ages.

Book excerpt: Principles of Precambrian Geologyis an update to the 1991 book, Precambrian Geology: The Dynamic Evolution of the Continental Crust, by the same author. The new edition covers the same topics in a more concise and accessible format and is replete with explanatory figures, tables, and illustrations. The book serves as a modern comprehensive statement on the Earth's Precambrian crust, covering the main aspects of distribution, lithiostratigraphy, age, and petrogenesis of Precambrian rocks by continent within the context of the Earth's evolving continental crust. Principles of Precambrian Geology provides a suitable framework for assessing various Earth dynamic and biospheric hypotheses, including the modern plate tectonic paradigm and the Gaian hypothesis. Despite the concise format, the new edition provides extensive updated references to support the information presented. It is designed to serve the needs of student, teacher, explorationist and general student of the continental crust. - Updated to provide more concise accessible information - Extensive illustrations, tabulations, and maps - Provides a framework for assessing recent hypothesis on Earth dynamics - Covers main aspects of distribution, lithostratigraphy, age, and protogenesis of Precambrian rocks

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.

Available in PDF, EPUB and Kindle. Book excerpt: Nickel Sulfide Ores and Impact Melts: Origin of the Sudbury Igneous Complex presents a current state of understanding on the geology and ore deposits of the Sudbury Igneous Complex in Ontario, Canada. As the first complete reference on the subject, this book explores the linkage between the processes of meteorite impact, melt sheet formation, differentiation, sulfide immiscibility and metal collection, and the localization of ores by magmatic and post-magmatic processes. The discovery of new ore deposits requires industry and government scientists and academic scholars to have access to the latest understanding of ore formation process models that link to the mineralization of their host rocks. The ore deposits at Sudbury are one of the world's largest ore systems, representing a classic case study that brings together very diverse datasets and ways of thinking. This book is designed to emphasize concepts that can be applied across a broad range of ore deposit types beyond Sudbury and nickel deposit geology. It is an essential resource for exploration geologists, university researchers, and government scientists, and can be used in rock and mineral analysis, remote sensing, and geophysical applications. - Provides the only reference book to focus entirely on the Sudbury Igneous Complex - Brings together an understanding of ore deposit and impact melts as a basis for future exploration - Authored by a leading expert on the geology of the Sudbury Igneous Complex with 35 years of experience working on nickel sulfide ore deposits

Available in PDF, EPUB and Kindle. Book excerpt: Geology and Landscape Evolution: General Principles Applied to the United States, Third Edition is an accessible text that balances interdisciplinary theory and applications within the physical geography, geology, geomorphology and climatology of the United States. The vast diversity of terrain and landscape across the United States makes this an ideal tool for geoscientists worldwide who research the country's geological and landscape evolution. The book provides an explanation of how landscape forms and how it evolves. This edition is fully updated with 3 additional sections: Geologic and Tectonic Processes and Provinces; Surface Processes and Provinces; and Compressional Mountain Systems. Rather than limiting the coverage specifically to tectonics or to the origin and evolution of rocks with little regard for the actual landscape beyond general desert, river, and glacial features, this book concentrates specifically on the origin of the landscape itself, with specific and exhaustive references and examples from across the United States. The book goes on to apply those concepts to specific examples throughout the United States, making it a valuable resource for understanding theoretical geological concepts through a practical lens. - Presents the complexities of physical geography, geology, geomorphology and climatology of the United States through an interdisciplinary, highly accessible approach - Offers hundreds of figures, maps and photographs that capture the systematic interaction of land, rock, rivers, glaciers, global wind patterns and climate, including Google Earth images - Provides a thorough assessment of the logic, rationale, and tools required to understand how to interpret landscape and the geological history of the Earth - Features exercises that conclude each chapter, aiding in the retention of key concepts - Includes 3 new sections and 8 additional chapters, as well as major updates to chapters throughout

Available in PDF, EPUB and Kindle. Book excerpt: Geology and Health is an integration of papers from geo-bio-chemical scientists on health issues of concern to humankind worldwide, demonstrating how the health and well-being of populations now and in the future can benefit through coordinated scientific efforts. International examples on dusts, coal, arsenic, fluorine, lead, mercury, and water borne chemicals, that lead to health effects are documented and explored. They were selected to illustrate how hazards and potential hazards may be from natural materials and processes and how anthropomorphic changes may have contributed to disease and debilitation instead of solutions. Introductory essays by the editors highlight some of the progress toward scientific integration that could be applied to other geographic sites and research efforts. A global purview and integration of earth and health sciences expertise could benefit the future of populations from many countries. Effective solutions to combat present and future hazards will arise when the full scope of human interactions with the total environment is appreciated by the wide range of people in positions to make important and probably expensive decisions. A case to illustrate the point of necessary crossover between Geology and Health was the drilling of shallow tube wells in Bangladesh to provide non-contaminated ground water. This "good" solution unfortunately mobilized arsenic from rocks into the aquifer and created an unforeseen or 'silent' hazard: arsenic. Geologists produce maps of earth materials and are concerned with natural processes in the environment with long time-frame horizons. The health effects encountered through changing the water source might have been avoided if the hydrological characteristics of the Bangladesh delta had been known and any chemical hazards had been investigated and documented. A recurrence of this type of oversight should be avoidable when responsible parties, often government officials, appreciate the necessity of such integrated efforts. The book extols the virtues of cooperation between the earth, life and health sciences, as the most practical approach to better public health worldwide.
