Download or read book Tectonics of Sedimentary Basins written by Cathy Busby and published by John Wiley & Sons. This book was released on 2011-12-07 with total page 1034 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigating the complex interplay between tectonics and sedimentation is a key endeavor in modern earth science. Many of the world's leading researchers in this field have been brought together in this volume to provide concise overviews of the current state of the subject. The plate tectonic revolution of the 1960's provided the framework for detailed models on the structure of orogens and basins, summarized in a 1995 textbook edited by Busby and Ingersoll. Tectonics of Sedimentary Basins: Recent Advances focuses on key topics or areas where the greatest strides forward have been made, while also providing on-line access to the comprehensive 1995 book. Breakthroughs in new techniques are described in Section 1, including detrital zircon geochronology, cosmogenic nuclide dating, magnetostratigraphy, 3-D seismic, and basin modelling. Section 2 presents the new models for rift, post-rift, transtensional and strike slip basin settings. Section 3 addresses the latest ideas in convergent margin tectonics, including the sedimentary record of subduction intiation and subduction, flat-slab subduction, and arc-continent collision; it then moves inboard to forearc basins and intra-arc basins, and ends with a series of papers formed under compessional strain regimes, as well as post-orogenic intramontane basins. Section 4 examines the origin of plate interior basins, and the sedimentary record of supercontinent formation. This book is required reading for any advanced student or professional interested in sedimentology, plate tectonics, or petroleum geoscience.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The Himalaya–Karakoram–Tibet mountain belt resulted from Cenozoic collision of India and Asia and is frequently used as the type example of a continental collision orogenic belt. The last quarter of a century has seen the publication of a remarkably detailed dataset relevant to the evolution of this belt. Detailed fieldwork backed up by state-of-the-art structural analysis, geochemistry, mineral chemistry, igneous and metamorphic petrology, isotope chemistry, sedimentology and geophysics produced a wide-ranging archive of data-rich scientific papers. The rationale for this book is to provide a coherent overview of these datasets in addressing the evolution of the mountain ranges we see today. This volume comprises 21 specially invited review papers on the Himalaya, Kohistan arc, Tibet, the Karakoram and Pamir ranges. These papers span the history of Himalayan research, chronology of the collision, stratigraphy, magmatic and metamorphic processes, structural geology and tectonics, seismicity, geophysics, and the evolution of the Indian monsoon. This landmark set of papers should underpin the next 25 years of Himalayan research.

Book excerpt: Andean Tectonics addresses the geological evolution of the Andes Mountains, the prime global example of subduction-related mountain building. The Andes forms one of the most extensive mountain belts on Earth, spanning approximately an 8,000 km distance along the western edge of South America, from 10°N to 55°S. The tectonic history of the Andes involves a rich record of diverse geological processes, including crustal deformation, magmatism, sedimentary basin evolution, and climatic interactions. This book addresses the range of Andean tectonic processes and their temporal and spatial variations. This critical resource is ideal for researchers interested in the causes and consequences of Andean-type orogenesis and the long-term evolution of fold-thrust belts, magmatic arcs, and forearc and foreland basins. Evaluates the history of Andean mountain building over the past 250 million years (the Mesozoic and Cenozoic eras) Integrates recent results and provides new perspectives on the complementary records of deformation, magmatism and sedimentary basin evolution, along with their interactions in time and space Provides insights into the development of the northern, central and southern Andes, all of which have typically been considered in isolation

Download or read book Tectonic Evolution of the Easternmost Himalayan Collisional System written by Peter Jasura Haproff and published by . This book was released on 2018 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cenozoic India-Asia collision generated the Tibetan Plateau and the Himalayan collisional system, the latter consisting of the convergence-perpendicular Himalayan orogen and the convergence-parallel Eastern and Western Flanking Belts located along the margins of India. Studying the evolution of each of these tectonic domains is critical to understanding the collision process and differentiating the end-member models of indenter-induced continental deformation. Despite this importance, there is a notable lack of geologic investigations on the development of the flanking belts in comparison to the extensive research of the Tibetan Plateau and east-trending Himalayan orogen. To address this problem, the research of this dissertation is focused on the Mesozoic-Cenozoic tectonic evolution of the northernmost segment of the Eastern Flanking Belt, the northern Indo-Burma Ranges, which are located directly east to southeast of the eastern Himalayan syntaxis. In the following chapters, I integrate the results of geologic field mapping, balanced cross section construction and restoration, U-Pb zircon geochronology, whole-rock geochemistry, thermobarometry, and (U-Th)/He zircon thermochronology to examine the litho-structural framework of the northern Indo-Burma Ranges and tectonic relationships in time and space with the adjacent eastern Himalayan orogen, the southern Tibetan Plateau, and the Eastern Flanking Belt. The research of this dissertation shows that the study area exposes a southwest- to west-directed Cenozoic thrust belt cored by a hinterland-dipping duplex system. Thrust faults sole into a northeast- to east-dipping di collement, which extends to >30 km depth. Southwestward forward propagation of the thrust belt in the foreland was coeval with out-of-sequence thrusting in the hinterland. This structural framework combined with the observed southward deflection in the trends of ductile stretching lineations within shear zones (northeast-trending in the north and east-trending in the south) suggest deformation around the eastern Himalayan syntaxis is best approximated by models of clockwise lithospheric flow accommodated by distributed thrusting. Major lithologic units involved in the northern Indo-Burma thrust belt from south to north include the easternmost continuations of the Tertiary Sub-Himalayan Sequence, Proterozoic-Cambrian Lesser Himalayan Sequence, and Indus-Yarlung suture zone of the Himalayan orogen and the Mesozoic northern Gangdese batholith belt and Mesoproterozoic basement of the Lhasa terrane. However, several Himalayan-Tibetan lithologic units are missing, including the Paleoproterozoic-Ordovician Greater Himalayan Crystalline Complex, Proterozoic-Eocene Tethyan Himalayan Sequence, Mesozoic-Cenozoic Xigaze forearc basin, and Cenozoic igneous rocks of the southern Gangdese batholith. Research suggests that these units were present in the study area at the onset of the Cenozoic India-Asia collision and their present-day absence is related to an eastward increase in post-collisional crustal shortening and continental underthrusting along the Himalayan collisional system. This interpretation is supported by a Cenozoic shortening strain estimate of ~81% (>156 km) across the northern Indo-Burma Ranges and a dramatic southward decrease in the width of the collisional system from ~200 km across the Himalayan orogen to ~5 km across the study area. Active deformation across the northern Indo-Burma Ranges and adjacent southeastern Tibetan Plateau is characterized by right-slip transpression partitioned between the range-bounding, oblique-slip Mishmi thrust in the southwest and right-slip Puqu and Parlung faults of Jiali fault zone in the northeast. The leading Mishmi thrust is kinematically-linked with the ~1000-km-long, right-slip Sagaing fault to the south via a previously-unmapped, southwest-trending restraining bend. This structural relationship of the Eastern Flanking Belt provides a key example of the spatial transition from transpressional deformation near the corner of an indenter to discrete right-slip motion along the side of an indenter during continental collision.

Available in PDF, EPUB and Kindle. Book excerpt: The book provides a model for the structural evolution of the Himalaya with relevant background information making it easily accessible to earth scientists specializing in other areas. The book is divided into two parts: The first part describes the basic principles of structural geology that are required to understand the evolutionary model described in the second part. The book incorporates some of the commonly ignored structural features, such as Pre-Himalayan rift tectonics, reactivation of faults, simultaneous development of folds and thrust faults, superposed folds, strike-slip faults developed during early and superposed deformation, problems with GPS data, erratic crustal shortening obtained by restoration of deformed sections, etc. The proposed model is essentially based on inversion tectonics and provides answers to some previously unresolved questions. It describes in detail the structure of the Himalaya as a primary arc, with supporting evidence from model deformation under controlled boundary conditions and anisotropy of magnetic susceptibility studies.

Download or read book Insights Into the Growth and Decay of Orogenic Wedges from Foreland Basin Successions written by Theresa M. Schwartz and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Convergent plate margins are dynamic settings where the evolution of sedimentary basins is influenced by a variety of interrelated autogenic and allogenic processes. These include plate tectonic-scale processes such as plate subduction and the development of a volcanic arc, fold-thrust belt, and associated basins; the development of climatic gradients across the orogen; shallow-crustal structural partitioning of the basins into discrete depocenters; and the surficial (topographic) responses to such events. This dissertation examines the interplay of tectonic, sedimentary, and climatic processes during the evolution of two retroarc foreland basin systems: the Late Cretaceous-Eocene Magallanes-Austral basin of Patagonia (Chapters 2 and 3) and the Late Cretaceous-Oligocene Rocky Mountain foreland basin of southwestern Montana (Chapter 4). These chapters investigate a variety of geologic processes that occur at different temporal and spatial scales. Specifically, major goals of this dissertation include (1) generating a paleogeographic reconstruction of latest Cretaceous depositional environments in the Magallanes-Austral basin to better understand the termination of the long-lived deep-marine foreland basin (Chapter 2); (2) utilizing detrital zircon U-Pb ages to understand variations in sediment dispersal patterns and long-term average sedimentation rates during shoaling of the Magallanes-Austral basin (Chapter 3); and (3) integrating structural, stratigraphic, sediment provenance, and stable isotope ([delta] 18O, [delta] 13C) data to better understand the spatial and temporal relationships of tectonic activity and climate (Chapter 4). Data types and methods are diverse, and include detailed outcrop description, detrital zircon U-Pb geochronology, thin-section petrography, 1-D subsidence modelling, and stable isotope ([delta] 18O, [delta] 13C) stratigraphy from calcic paleosols.

Book excerpt: "Spanning eight kilometers of topographic relief, the Himalayan fold-thrust belt in Nepal has accommodated more than 700 km of Cenozoic convergence between the Indian subcontinent and Asia. Rapid tectonic shortening and erosion in a monsoonal climate have exhumed greenschist to upper amphibolite facies rocks along with unmetamorphosed rocks, including a 5-6-km-thick Cenozoic foreland basin sequence. This Special Paper presents new geochronology, multisystem thermochronology, structural geology, and geological mapping of an approximately 37,000 km2 region in midwestern and western Nepal. This work informs enduring Himalayan debates, including how and where to map the Main Central thrust, the geometry of the seismically active basal Himalayan detachment, processes of tectonic shortening in the context of postcollisional India-Asia convergence, and long-term geodynamics of the orogenic wedge"--Publisher's website

Download or read book Weathering and Climate in the Himalaya Since the Miocene - Insights from Foreland Basin Sediments written by Natalie Vögeli and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Himalaya orogen has major impact on global and regional climate and acts as an orographic barrier for atmospheric circulations. The interplay of the Asian monsoon system and the tectonic evolution of the mountain belt make it an ideal laboratory to study interactions between tectonics, climate and erosion, and its implications on weathering and atmospheric CO2 drawdown. Lateral variations in exhumation rates have been observed and studies on paleoclimate have been conducted in the central and western Himalaya, but the onset, the evolution and the characteristics of the monsoonal climate are still debated. Paleo weathering rates and intensities are challenging to reconstruct and remain poorly studied, especially in the eastern part of the orogen.This thesis focuses on lateral variations in climate, weathering and vegetation along the Himalayan mountain range, on weathering regimes in the eastern Himalaya since Miocene times, and on the implications for the evolution of the Asian monsoon. The foreland basin sediments of the pre-Siwalik and Siwalik Groups contain a record of tectonics and paleoclimate. The approach focuses on a direct west-east comparison; we therefore sampled three previously dated sedimentary sections in the western Himalaya, namely the Joginder Nagar, Jawalamukhi and Haripur Kolar, which combine into a timespan of 20 Ma, and the Kameng river section in the east, which spans over the last 13 Ma.Stable carbon isotopes on organic matter are used to reconstruct changes in vegetation. Stable carbon isotopes show important lateral variations, with a change toward more positive values in the west at ~7 Ma and in contrast no change in the east, indicating a change in vegetation from C3 to C4 plant in the west but not in the east. These variations implicate a change towards a dryer and more seasonal climate in the western Himalaya, whereas the climate in the eastern part remained too humid for C4 plants to evolve, due to its proximity to moisture source (Bay of Bengal).In order to reconstruct paleo weathering regimes by analyzing foreland basin sediments, it is important to take into account changes in provenance and possible influences of burial diagenesis. Results of heavy-mineral and petrographic analyses of the Kameng section provide better insight into diagenesis and provenance, showing that the older part of the Kameng section is influenced by diagenesis. Changes in provenance do not correlate with changes in clay mineralogy and major elements, which are therefore indicating an overall increase in weathering over time, with a remarkable change at ~8 Ma.The compilation of the three sections in the west represent one of the longest sedimentary records in the Himalayas, spanning over 20 Ma. Clay minerals show similar trends in the west and the east, indicating the development of a more seasonal climate starting at ~8 Ma. Major elements show a trend toward stronger weathering over time in the west and the east, but the western Himalaya are generally more weathered than in the east, which is consistent with the interpretation of the stable carbon isotope data, suggesting the climate to be more humid in the east. More runoff and erosion inhibit extensive weathering of the sediments, whereas dry sea sons with little runoff allow sediments to weather.Lithium isotopic compositions were measured on bulk sediments as a new approach to reconstruct chemical weathering rates, applied for the first time on Siwalik sediments. Results show a change in weathering intensity in the west, where lithium isotopic values become more positive over time, whereas, they stay relatively constant in the east. More positive values in the west, suggest that the system becomes more weathering-limited and more incongruent.

Download or read book Thermo-tectonic Record of Hyperextension, Structural Inversion, and Foreland Basin Evolution of the Eastern and Central Pyrenees written by Margaret Larkin Odlum and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct constraints on processes associated with rifting and mantle exhumation are necessary to understand the thermal and structural evolution of continental rift systems, and the role of pre-existing crustal architecture on orogenesis and foreland basin development. This work constrains the Early Cretaceous hyperextension history along the Iberia-European margin and how rift inheritance affected the structural and foreland basin evolution of the Late Cretaceous-Oligocene Pyrenean orogeny. Chapters 1 and 2 aim to understand the thermal and structural evolution of the North Pyrenean basement massifs during Early Cretaceous rifting and hyperextension using multi-mineral thermochronometry. These chapters integrate zircon, apatite, and rutile U‐Pb ages from the Agly and Saint Barthélémy massifs that provide new constraints to understand the decoupled versus coupled extensional evolution, exhumation timing of the middle‐lower crust, and the age of juxtaposition of the upper crust granitic pluton with middle crustal gneisses, and fluid-rock interactions along a detachment fault. Novel method integration and approaches using apatite were developed and implemented in these chapters to best interpret the apatite U-Pb ages to gain the most insight into thermal, structural, and fault zone processes in the Early Cretaceous rift system’s distal margin. Chapters 3 and 4 use the sedimentary record in the pro-wedge foreland basins of inversion and orogenesis to understand the provenance, hinterland evolution, and the role of extensional inheritance on the orogenic phase of the margin. This work shows that the eastern Pyrenean foreland basin deposits were sourced from Corsica-Sardinia and the Catalan Coastal Ranges during the Late Cretaceous-Paleocene, and the Pyrenees beginning in the Eocene. Detrital mineral trends across the basins suggest that the pro-wedge foreland basin developed and remained segmented throughout the Late Cretaceous-Oligocene. The results from these chapters highlight the dominant control of inherited structures and rift basins on controlling the sediment provenance and foreland basin architecture in inverted rift systems. The dissertation aims to show the structural evolution of the Early Cretaceous rifting and thermal and structural processes that were operating within the continental crust at the rift margin, and how this inherited rift architecture affected the orogenic evolution and foreland basin development during the Pyrenean orogeny. These results add to our overall understanding of the structural and thermal evolution during rifting and continental break-up and role of rift inheritance in the evolution of superimposed orogenic systems and their associated foreland basins
