Available in PDF, EPUB and Kindle. Book excerpt: As a final product of the International Geological Correlation Program (IGCP) Project 217, this volume brings together significant advances in the understanding of Proterozoic crustal evolution. This IGCP Project focussed on nine research objectives: 1) Comparison of Archean and Proterozoic supracrustal assemblages to more fully understand differences between Archean and post-Archean tectonic regimes; 2) To more fully understand the geochemical differences between Archean and post-Archean sediments and to evaluate the various factors that control sediment composition; 3) From combined U/Pb zircon and whole-rock Sm/Nd studies, to see if the apparent 2.4-2.0 continental crust "generation gap" is real; 4) To employ new techniques in the dating of individual zircons to more fully understand Proterozoic tectonic history and the role of crustal reworking; 5) From trace element ratios and Nd isotopic data from basalts, to better understand Proterozoic mantle evolution; 6) To encourage more detailed studies of the anorogenic granite-anorthosite association to better understand its origin and significance in terms of crustal evolution; 7) From combined Nd, Pb, and Sr isotopic data, to more precisely estimate the amount of new continental crust formed during the Proterozoic; 8) To encourage joint P-T and geochronological studies of Proterozoic and high-grade terranes to better understand Proterozoic orogenesis: and 9) To try and understand why hydrothermal precious metal deposits are relatively rare in the Proterozoic compared to both the Archean and the Phanerozoic. The book should be of interest to professionals in the geosciences (especially geochemists, petrologists and structural geologists) and graduate students in the same fields.

Download or read book Ancient Landscapes of Western North America written by Ronald C. Blakey and published by Springer. This book was released on 2017-10-03 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Allow yourself to be taken back into deep geologic time when strange creatures roamed the Earth and Western North America looked completely unlike the modern landscape. Volcanic islands stretched from Mexico to Alaska, most of the Pacific Rim didn’t exist yet, at least not as widespread dry land; terranes drifted from across the Pacific to dock on Western Americas’ shores creating mountains and more volcanic activity. Landscapes were transposed north or south by thousands of kilometers along huge fault systems. Follow these events through paleogeographic maps that look like satellite views of ancient Earth. Accompanying text takes the reader into the science behind these maps and the geologic history that they portray. The maps and text unfold the complex geologic history of the region as never seen before. Winner of the 2021 John D. Haun Landmark Publication Award, AAPG-Rocky Mountain Section
Download or read book The Geology of Kane County Utah written by Hellmut H. Doelling and published by Utah Geological Survey. This book was released on 1989-01-25 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kane County, with its 4105 square miles, lies along the south-central margin of Utah and is found in the western part of the Colorado Plateaus physiographic province. It is famous for scenic beauty displayed in its colorful rock formations and other geologic features such as faults, folds, arches, monoclines, joints, cross beds, cliffs, lava fields, and canyons. Kane County contains parts of Bryce and Zion National Parks, the Glen Canyon Recreation Area, and it is home to the Coral Pink Sand Dunes and Kodachrome Basin State Parks. The county area has had an interesting geologic history and important fossil finds have added much to our knowledge of world geology. The total value of the mineral production of Kane County, Utah through 1985 is estimated at $21,854,000, of which more than 95 percent is attributed to construction materials, mined or quarried to build and maintain highways. Sand and gravel, crushed stone, coal, gemstones, pumice and volcanic ash, manganese ore, gold, uranium, silver, copper and lead were or have been produced, with the most important current commodities being construction and gem materials. The annual rate of production of these items is erratic, but the value averages a few hundred thousand dollars annually. The production of the construction materials is dependent on the schedules of the Utah Department of Transportation and other road building agencies. Gem materials are mined intermittently to supply the tourist trade. Currently, there are no large, regularly producing mining operations in the county. Other mineral deposits reported in Kane County include titanium and zirconium, gypsum and anhydrite, limestone and dolomite, clay, and vanadium. About 29 tests for petroleum have thus far been drilled without significant success. However, many had interesting shows of oil and gas and the potential for discovery remains high. 192 pages + 10 plates

Download or read book Large Rivers written by Avijit Gupta and published by John Wiley & Sons. This book was released on 2008-02-28 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large Rivers: Geomorphology and Management explores an important topic in geomorphology and sedimentology: the form and function of major rivers. Our knowledge of the big rivers of the world is limited. It is currently difficult to recognise large rivers of the past from relict sedimentary deposits or to structure management policies for long international rivers. This exciting book brings together a set of papers on large rivers of the world, as a unique introduction to a demanding subject. The book includes thirty chapters and is organised into three sections. The first part is on the environmental requirements for creating and maintaining a major river system. The second is a collection of case studies on 14 large rivers from different continents, covering a range of physical environments. The third section includes chapters on the measurement and management of large rivers. First book to offer in a single volume state-of-the-art knowledge on management and geomorphology of large rivers of the world A pioneering study, pushing the boundaries of our knowledge related to big rivers Includes comprehensive case studies covering the major large rivers of the world including Amazon, Mississippi, Nile, Congo, Indus, and Mekong Written by a leading team of distinguished, international contributors Large Rivers: Geomorphology and Management is essential reading for postgraduate students and researchers in fluvial geomorphology, hydrology, sedimentary geology, and river management. It is also of relevance to engineers and environmental consultants in the private and public sectors working on major rivers of the world.
