Download or read book Late Pleistocene holocene Slip Rates in the Northwestern Zagros Mountains Kurdistan Region of Iraq Derived from Luminescence Dating of River Terraces and Structural Modeling written by Mjahid Zebari and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: A significant amount of the ongoing shortening between the Eurasian and Arabian plates is accommodated within the Zagros Fold-Thrust Belt. However, the spatial and temporal distribution of active shortening within the belt, especially in its NW part, is not yet well constrained. We determined depositional ages of uplifted river terraces crossing the belt along the Greater Zab River using luminescence dating. Kinematic modeling of the fault-related fold belt was then used to calculate long-term slip rates during the Late Pleistocene to Holocene. Our results provide new insight into the rates of active faulting and folding in the area. The Zagros Mountain Front Fault accommodates about 1.46 ± 0.60 mm a−1 of slip, while a more external basement fault further to the SW accommodates less than 0.41 ± 0.16 mm a−1. Horizontal slip rates related to detachment folding of two anticlines within the Zagros Foothills are 0.40 ± 0.10 and 1.24 ± 0.36 mm a−1. Basement thrusting and thickening of the crust are restricted to the NE part of the Zagros belt. This is also reflected in the regional topography and in the distribution of uplifted terraces. In the southwestern part, the deformation is limited mainly to folding and thrusting of the sedimentary cover above a Triassic basal detachment. In the NE, deformation is associated with slip on basement thrusts. Our study sheds light on the distribution of shortening in the Zagros Mountains and helps to understand the regional tectonic system. Our results may be the foundation for a better seismic hazard assessment of the entire area
Download or read book Holocene Left slip Rate Determined by Cosmogenic Surface Dating on the Xidatan Segment of the Kunlun Fault Qinghai Chin written by and published by . This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmogenic dating, using in-situ 26A1 and 10Be in quartz pebbles from alluvial terrace surfaces, constrains the late Holocene slip rate on the Xidatan segment of the Kuniun fault in northeastern Tibet. Two terrace risers offset by 24 " 3 and 33 f" 4m, having respective ages of 1788 " 388 and 2914 " 471 yr, imply a slip rate of 12.1 " 2.6 mm/yr. The full range of ages obtained ((less than or equal to) 22.8 k.y., most of them between 6.7 and 1.4 k.y.) confirm that terrace deposition and incision, hence landform evolution, are modulated by post-glacial climate change. Coupled with minimum offsets of 9-12 m, this slip rate implies that great earthquakes (M-8) with a recurrence time of 800-1000 yr. rupture the Kunlun fault n.
Download or read book Tectonics of the Himalaya written by S. Mukherjee and published by Geological Society of London. This book was released on 2015-09-28 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Himalayan mountain belt, which developed during the India–Asia collision starting about 55 Ma ago, is a dramatically active orogen and it is regarded as the classic collisional orogen. It is characterized by an impressively continuous 2500 km of tectonic units, thrusts and normal faults, as well as large volumes of high-grade metamorphic rocks and granites exposed at the surface. This constitutes an invaluable field laboratory, where amazing crustal sections can be observed directly in very deep gorges. It is possible to unravel the tectonic and metamorphic evolution of litho-units, to observe the mechanisms of exhumation of deep-seated rocks and the propagation of the deformation. Himalayan tectonics has been the target of many studies from numerous international researchers over the years. In the last 15 years there has been an explosion of data and theories from both geological and geophysical perspectives. This book presents the results of integrated multidisciplinary studies, including geology, petrology, magmatism, geochemistry, geochronology and geophysics, of the structures and processes affecting the continental lithosphere. These processes and their spatial and temporal evolution have major consequences on the geometry and kinematics of the India–Eurasia collision zone.
Download or read book Dolmens in the Levant written by James A. Fraser and published by Routledge. This book was released on 2018-01-17 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Western explorers first encountered dolmens in the Levant, they thought they had discovered the origins of a megalithic phenomenon that spread as far as the Atlantic coast. Although European dolmens are now considered an unrelated tradition, many researchers continue to approach dolmens in the Levant as part of a trans-regional phenomenon that spanned the Taurus mountains to the Arabian peninsula. By tightly defining the term 'dolmen' itself, this book brings these mysterious monuments into sharper focus. Drawing on historical, archaeological and geological sources, it is shown that dolmens in the Levant mostly concentrate in the eastern escarpment of the Jordan Rift Valley, and in the Galilean hills. They cluster near proto-urban settlements of the Early Bronze I period (3700–3000 BCE) in particular geological zones suitable for the extraction of megalithic slabs. Rather than approaching dolmens as a regional phenomenon, this book considers dolmens as part of a local burial tradition whose tomb forms varied depending on geological constraints. Dolmens in the Levant is essential for anyone interested in the rise of civilisations in the ancient Middle East, and particularly those who have wondered at the origins of these enigmatic burial monuments that dominate the landscape.

Download or read book Kinematic Evolution and Structural Styles of Fold and thrust Belts written by J. Poblet and published by Geological Society of London. This book was released on 2011 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fold-and-thrust belts occur worldwide, have formed in all eras of geological time, and are widely recognized as the most common mode in which the crust accommodates shortening. Much current research on the structure of fold-and-thrust belts is focused on structural studies of regions or individual structures and on the geometry and evolution of these regions employing kinematic, mechanical and experimental modelling. In keeping with the main trends of current research, this title is devoted to the kinematic evolution and structural styles of a number of fold-and-thrust belts formed from palaeozoic to recent times. The papers included in this book cover a broad range of different topics, from modelling approaches to predict internal deformation of single structures, 3D reconstructions to decipher the structural evolution of groups of structures, palaeomagnetic studies of portions of fold-and-thrust belts, geometrical and kinematical aspects of Coulomb thrust wedges and structural analyses of fold-and-thrust belts to unravel their sequence of deformations--
Download or read book Reservoir Characterization written by Larry Lake and published by Elsevier. This book was released on 2012-12-02 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reservoir Characterization is a collection of papers presented at the Reservoir Characterization Technical Conference, held at the Westin Hotel-Galleria in Dallas on April 29-May 1, 1985. Conference held April 29-May 1, 1985, at the Westin Hotel—Galleria in Dallas. The conference was sponsored by the National Institute for Petroleum and Energy Research, Bartlesville, Oklahoma. Reservoir characterization is a process for quantitatively assigning reservoir properties, recognizing geologic information and uncertainties in spatial variability. This book contains 19 chapters, and begins with the geological characterization of sandstone reservoir, followed by the geological prediction of shale distribution within the Prudhoe Bay field. The subsequent chapters are devoted to determination of reservoir properties, such as porosity, mineral occurrence, and permeability variation estimation. The discussion then shifts to the utility of a Bayesian-type formalism to delineate qualitative ""soft"" information and expert interpretation of reservoir description data. This topic is followed by papers concerning reservoir simulation, parameter assignment, and method of calculation of wetting phase relative permeability. This text also deals with the role of discontinuous vertical flow barriers in reservoir engineering. The last chapters focus on the effect of reservoir heterogeneity on oil reservoir. Petroleum engineers, scientists, and researchers will find this book of great value.
Download or read book Petrogenesis and Exploration of the Earth s Interior written by Domenico M. Doronzo and published by Springer. This book was released on 2019-02-22 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume is based on the best papers accepted for presentation during the 1st Springer Conference of the Arabian Journal of Geosciences (CAJG-1), Tunisia 2018. The book is of interest to all researchers in the fields of Mineralogy, Geochemistry, Petrology and Volcanology. The Earth's interior is a source of heat, which makes our planet unique. This source regulates the formation and evolution of rocks at larger scales, and of minerals and sediments toward smaller scales. In such context, the exploration of georesources (products) has to be related to petrogenesis (processes). This volume offers an overview of the state-of-the-art petrogenesis and exploration in, but not limited to, the Middle East and Mediterranean regions. It gives new insights into processes and products related to the Earth's interior, and associated georesources by international researchers. Main topics include: 1. Petrogenetic processes: geochemistry, geochronology and geophysical approaches 2. Surficial processes: sedimentation and facies analysis 3. Applied mineralogy and tectonics 4. Geological research applied to mineral deposits
Download or read book Copahue Volcano written by Franco Tassi and published by Springer. This book was released on 2015-09-21 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive description of the volcanological, petrological and geochemical features of the Copahue volcano, located at the border between Argentina and Chile. Scientific studies are limited for this volcanic system, due to its remote location and difficult access in winter. However, Copahue is one of the most active volcanic systems in the southern Andes. Monitoring the volcano's activity is of utter importance, as it provides means of existence for the nearby village of the same name, hosting the world's highest-located hot-springs resort. This book's aim is to present the current monitoring activities, and to describe future research programs that are planned in order to mitigate volcanic hazards. Special attention is therefore devoted to the social and industrial activities close to the volcano, such as health therapies and geothermal energy exploitation. In a special section, the Copahue volcano is presented as a terrestrial modern analog for early-Earth and Mars environments.

Download or read book Rivers and Floodplains written by John S. Bridge and published by John Wiley & Sons. This book was released on 2009-04-01 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers and Floodplains is concerned with the origin, geometry, water flow, sediment transport, erosion and deposition associated with modern alluvial rivers and floodplains, how they vary in time and space, and how this information is used to interpret deposits of ancient rivers and floodplains. There is specific reference to the types and lifestyles of organisms associated with fluvial environments, human interactions with rivers and floodplains, associated environmental and engineering concerns, as well as the economic aspects of fluvial deposits, particularly the modeling of fluvial hydrocarbon reservoirs and aquifers. Methods of studying rivers and floodplains and their deposits are also discussed. Although basic principles are emphasized, many examples are detailed. Particular emphasis is placed on how an understanding of the nature of modern rivers and floodplains is required before any problems concerning rivers and floodplains, past or present, can be addressed rationally. Rivers and Floodplains is designed as a core text for senior undergraduate and graduate students studying modern or ancient fluvial environments, particularly in earth sciences, environmental sciences and physical geography, but also in civil and agricultural engineering. College teachers, researchers, and practising professionals will also find the book an invaluable reference. Presents a process-based approach, which is relevant to modern curricula.

Teachers, researchers and practising professionals will find this an invaluable reference tool. Rivers and Floodplains will also be of interest to geologists, geographers and engineers.
Download or read book The Emergence of the Acheulean in East Africa and Beyond written by Rosalia Gallotti and published by Springer. This book was released on 2018-08-17 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume presents current archaeological research and data from the major early Acheulean sites in East Africa, and addresses three main areas of focus; 1) the tempo and mode of technological changes that led to the emergence of the Acheulean in East Africa; 2) new approaches to lithic collections, including lithic technology analyses; and 3) the debated coexistence of the Developed Oldowan and the early Acheulean. The chapters are the proceedings from the workshop titled “The Emergence of the Acheulean in East Africa”, held at University of Rome “La Sapienza” on September 12–13, 2013. The aim of the workshop was to bring together researchers currently working in this field in East Africa, in order to define the characteristics and the evolution of the early Acheulean. The volume was expanded with some chapters on the preceding Oldowan, on the African fauna and on paleovegetation, on the Acheulean in Asia and, eventually, on the Acheulean in Europe. The book is addressed to the scientific community, and will be of interest to researchers, graduate students, archaeologists, paleontologists, and paleoanthropologists. This volume is dedicated to the memory of Jean Chavaillon (March 25, 1925 - December 21, 2013), the leading archaeologist and Quaternary geologist who researched with unfailing enthusiasm the earliest human cultures and directed from 1965 to 1995 the French Archaeological Mission at Melka Kunture.
Download or read book The Palaeolithic Settlement of Asia written by Robin Dennell and published by Cambridge University Press. This book was released on 2008-12-15 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first analysis and synthesis of the evidence of the earliest inhabitants of Asia before the appearance of modern humans 100,000 years ago. Asia has received far less attention than Africa and Europe in the search for human origins, but is no longer considered of marginal importance. Indeed, a global understanding of human origins cannot be properly understood without a detailed consideration of the largest continent. In this study, Robin Dennell examines a variety of sources, including the archaeological evidence, the fossil hominin record, and the environmental and climatic background from Southwest, Central, South, and Southeast Asia, as well as China. He presents an authoritative and comprehensive framework for investigations of Asia's oldest societies, challenges many long-standing assumptions about its earliest inhabitants, and places Asia centrally in the discussions of human evolution in the past two million years.
