DOWNLOAD EBOOK"This book is a must-read for researchers interested in extensional tectonics in general and the Neogene tectonics of the Basin and Range in particular, because it challenges, on the basis of more than 50 years of field studies, the existing paradigm of province-wide uniformly large extension and replaces it with a model integrating extension with extension-normal shortening-both as primary strains. The first chapter takes the reader on two journeys southwestward from central Utah through the Lake Mead area: the first to emphasize the lack of uniformly distributed or integrated extension and the second to highlight left-lateral shear at 13 localities along the east margin of the Basin and Range that is kinematically compatible with right-lateral shear along the west margin. The compatibility provides a basis for understanding the extreme Neogene tectonics of the Lake Mead area. The second chapter summarizes multifaceted field evidence from the well-studied eastern Lake Mead area as a focused example of the need for a complete revision of the extensional paradigm." -- Publisher's description.

DOWNLOAD EBOOKLandscape Evolution of Continental-Scale River Systems: A Case Study of North America's Pre-Pleistocene Bell River Basin provides a detailed case study and complete analysis of this continental-scale North American paleo-river system. The book uses detrital zircon provenance data to link incision of the Grand Canyon to deposition of its erosional products in a giant drowned delta in the Labrador Sea, in the context of sedimentary source-to-sink processes and Plio-Pleistocene continental drainage changes. The case study describes the tectonic changes in this continental-scale paleo-river system, with global implications, and contrasts this system to other continental-scale river systems around the world. This book is a valuable reference for postgraduate students, academics and researchers in the fields of geology, fluvial geomorphology and other geosciences. Readers will be able to use this detailed case study to better understand the implications for how active tectonics of headwaters regions influence delta deposition in continental-scale river systems around the world. - Details the landscape evolution of a continental-scale paleo-river system using detrital zircon geochronology with fluvial processes - Provides a multidisciplinary case study with applications to other continental-scale river systems around the world - Compares and contrasts the Bell river to the Amazon and uses these examples as analogs to discuss other systems

DOWNLOAD EBOOKThis 27-page report analyzes new detailed (1:12,000 scale) geologic mapping of a 14 square mile area centered by the high-temperature (350°F) Sulphurdale heat source, which at the surface makes up a circular area about a mile in diameter that is likely caused by a magma body at depth. A former small steam-driven geothermal electric power plant in the circular area is being replaced by a larger plant (Enel Green Power North America) that will use binary technology. Five cross sections tied to and at the same scale as the map help interpret the likely extent of the geothermal resource. Sulfur derived from evaporites at depth was initially mined at a solfatara above the heat source; associated sulfuric acid seeped downward to remove the Kaibab Limestone and Toroweap Formation from the subsurface.

DOWNLOAD EBOOKGeomechanics investigates the origin, magnitude and deformational consequences of stresses in the crust. In recent years awareness of geomechanical processes has been heightened by societal debates on fracking, human-induced seismicity, natural geohazards and safety issues with respect to petroleum exploration drilling, carbon sequestration and radioactive waste disposal. This volume explores the common ground linking geomechanics with inter alia economic and petroleum geology, structural geology, petrophysics, seismology, geotechnics, reservoir engineering and production technology. Geomechanics is a rapidly developing field that brings together a broad range of subsurface professionals seeking to use their expertise to solve current challenges in applied and fundamental geoscience. A rich diversity of case studies herein showcase applications of geomechanics to hydrocarbon exploration and field development, natural and artificial geohazards, reservoir stimulation, contemporary tectonics and subsurface fluid flow. These papers provide a representative snapshot of the exciting state of geomechanics and establish it firmly as a flourishing subdiscipline of geology that merits broadest exposure across the academic and corporate geosciences.

DOWNLOAD EBOOKThis volume focuses on the geometry, kinematic development, and origin of regional segmentation structures within the basin and range province of Western North America. Contributions range from analysis of individiual structures to broad regional syntheses, including a map of basin and range structures and tilt domains. Several papers discuss the implications of regional segmentation structures in assessing seismic hazards, hydrocarbon and mineral resources, and ground-water supplies.

DOWNLOAD EBOOK"The Las Vegas Formation was established in 1965 to designate the distinctive light-colored, fine-grained, fossil-bearing sedimentary deposits exposed in and around the Las Vegas Valley, Nevada. In a coeval designation, the sediments were subdivided into informal units with stratigraphic and chronologic frameworks that have persisted in the literature. Use of the Las Vegas Formation name over the past half century has been hampered because of the lack of a robust definition and characterization of the entire lithostratigraphic sequence and its geographic distribution and chronology. This study evaluates and describes deposits attributed to the Las Vegas Formation with detailed stratigraphy, sedimentology, and field relations"--Provided by publisher.
