Book excerpt: This volume provides a state-of-the-art account of the geology of part of Central Asia named The Central Asian Orogenic Belt (CAOB). This Belt formed by accretion of island arcs, ophiolites, oceanic islands, seamounts, accretionary wedges, oceanic plateaux and microcontinents (c. 1000-250 Ma ago) by similar processes to those in the circum- Pacific Mesozoic-Cenozoic accretionary orogens. Also known as Altaids, this region is one of the largest orogenic belts on Earth, extending from the Ural Mountains in the West to far eastern Siberia. It is the product of a complex evolution lasting for more than 800 million years from the latest Mesoproterozoic to the end of the Palaeozoic. The CAOB consists of numerous accreted terranes, made up of island arcs, oceanic plateaux and islands, Precambrian microcontinents and remnants of oceanic crust that are preserved as fragmented ophiolites. Although the broad history if this huge territory is now reasonably well understood there are still major unanswered questions such as the rate and volume of crustal growth, the origin of continental fragments, the detailed mechanism of accretion and collision, the role of terrane rotations during the orogeny, and the age and composition of the lower crust in Central Asia. Large parts of Central Asia (Kazakhstan, Kyrgyzstan, Siberia and parts of Mongolia) treated in this volume have only been poorly covered in scholarly western publications. Most contributions of this book are by Russian scientists actively involved in field and laboratory research of the CAOB and therefore have an intimate knowledge of the terranes which they describe and analyze. In view of the increasing significance of Central Asia because of its wealth of mineral resources this volume is of interest to readers from all fields of the geosciences and from academics to industry.
Download or read book Whence the Mountains written by James W. Sears and published by Geological Society of America. This book was released on 2007-01-01 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 19 original papers on the tectonic evolution of mountain systems were collected to mark the 50th anniversary of Price's description of the Canadian Cordillera. A sampling of topics turns up the driving mechanism and three-dimensional circulation of plate tectonics, the Belt-Purcell Basic as the keystone of the Rocky Mountain fold-and-thrust belt in the US and Canada, Silurian-Devonian orogenic events in the central Appalachians and the crystalline southern Appalachians, and defining the eastern boundary of the North Asian craton from structural and subsidence history studies of the Verkhoyansk fold-and-thrust belt. A fold-out sheet of color maps and diagrams is tucked into a pocket inside the back cover.
Download or read book Structural Geometry of Mobile Belts of the Indian Subcontinent written by Tapas Kumar Biswal and published by Springer Nature. This book was released on 2020-02-21 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the latest research on the structural geology of the mobile belts of the Indian subcontinent including the Himalayas, NE Himalayas, Bangladesh thrust belt, Andaman subduction zone, the Aravalli‐Delhi, the Central India Tectonic Zone, the Singhbhum, the Eastern Ghats and the Southern granulite terrane. It offers essential information on deformational structures in the mobile belt, such as folding patterns, the character of the shear zone, shear strain analysis, and faults, as well as fault zone rocks. The findings presented here are based on field observations, mapping, sampling and analysis work (e.g. petrographic studies), as well as limited geochemical and geochronological analysis to support the findings. A discussion on the structural evolution of these mobile belts and their connections with other belts rounds out the coverage.
Download or read book Introduction to Geological Maps and Structures written by John L. Roberts and published by Elsevier. This book was released on 2013-10-22 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Geological Maps and Structures describes the basic methods to interpret and attain a better understanding of geological maps. The book describes the nature and preparation of geological maps, and then covers topics such as solid and drift maps, geological boundaries, sections, and the use of symbols. The book explains sedimentary rocks, outcrop patterns, and the topographic representation of geological structures. The text also addresses the geometry of folds and folding when pre-existing surfaces are distorted into zigzag patterns. The author explains in detail the morphology of folded layers and the mechanism involved in folding. He goes on to interpret the formation of outcrop patterns, as well as the structure of a cylindrical and cylindroidal fold patterns. The author also describes the different structures that result from the brittle fractures present in rocks that undergo massive stress. Of interest is the presentation of how fissures and mineral veins are formed and deposited. The author then discusses earth movements resulting in angular unconformities known as stratigraphic break. These breaks in the stratigraphic record, such as diastems, non-sequences, paraconformities, or disconformities, can be interpreted as the intervals of geological time. The book then explains the nature of tectonic maps, which involves features arising from the continental crust, and how these maps are different from geological maps that show the outcrop of lithostratigraphic units. Geologists, cartographers, meteorologists, seismologists, land use developers, and students of the earth sciences will find this book valuable.

This book was released on 2017-09-11 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dedicated to Bob Hatcher, this Memoir explores linkages between tectonic processes through a series of field-, numerical- and laboratory-based studies, concentrating on feedback mechanisms within ancient and evolving orogens by which individual or linked tectonic processes may influence or predetermine the operation of other processes in space and time. Case studies cover a wide range of ancient to modern orogens: the Svecofennian of southern Finland, the Gyeonggi Massif of Korea, the Caledonides of northern Scotland, the Variscan of the East European craton, the Appalachians of the eastern United States, the European Alps and Dinarides, north Cascades of the northwestern United States, and the Himalaya. Emphasis is placed on integration between data sets developed from a wide range of analytical approaches, including: field mapping, seismic reflection profiling, strain analyses, petrology, isotopic dating, and numerical modeling-based studies of thermal evolution associated with tectonic processes such as thrust-related burial and exhumation.

Download or read book Geology of the Appalachian Caledonian Orogen in Canada and Greenland written by Harold Williams and published by Geological Society of America. This book was released on 1995 with total page 951 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the Canadian Appalachian region. The chapter on the East Greenland Caledonides stands alone and there is no attempt to integrate the geological accounts of the two far removed regions. Rocks of the Canadian Appalachian region are described under four broad temporal divisions: lower Paleozoic and older, middle Paleozoic, upper Paleozoic, and Mesozoic. The rocks of these temporal divisions define geographic zones, belts, basins, and graben, respectively. The area is of special interest because so many modern concepts of mountain building are based on Appalachian rocks & structures.

This book was released on 2009 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accretionary orogens form at convergent plate boundaries and include the supra-subduction zone forearc, magmatic arc and backarc components. They can be broken into retreating and advancing types, based on their kinematic framework and resulting geological character.Accretionary systems have been active throughout Earth history, extending back until at least 3.2 Ga, and provide an important constraint on the initiation of horizontal motion of lithospheric plates on Earth. Accretionary orogens have been responsible for major growth of the continental lithosphere, through the addition of juvenile magmatic products, but are also major sites of consumption and reworking of continental crust through time.The aim of this volume is to provide a better understanding of accretionary processes and their role in the formation and evolution of the continental crust. Fourteen papers deal with general aspects of accretion and metamorphism and discuss examples of accretionary orogens and crustal growth through Earth history, from the Archaean to the Cenozoic.

Download or read book Geological Mapping of Our World and Others written by Robert W. H. Butler and published by Geological Society of London. This book was released on 2024-04-23 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Map-making is a fundamental tool for developing geological knowledge. It involves data collection and interpretation and has its roots in the earliest discoveries in Earth science. It is the starting point for stratigraphic and structural interpretations, metamorphic facies, geochronology and modelling studies – and underpins civil engineering. From the beginning, geological mapping rapidly evolved into far more than being a simple spatial catalogue of observable rock types and landforms on the Earth’s land-surface: deductive reasoning allows this knowledge to infer subsurface Earth structure. However, the same approaches have also been down-scaled to deduce processes on the grain-scale; or up-scaled to look out to extraterrestrial objects. This Special Publication draws together these strands, crossing geoscience disciplines and observation scales to celebrate geological mapping, its historical importance and future directions, and its use in applied geology together with developing knowledge of Earth and planetary evolution and processes.
