Book Synopsis Temporal Constraints on Progressive Rifting of a Hyper-extended Continental Margin Using Bedrock and Detrital Zircon (U-Th)/(Pb-He) Dating, Mauléon Basin, Western Pyrenees by : Nicole Rita Hart
Download or read book Temporal Constraints on Progressive Rifting of a Hyper-extended Continental Margin Using Bedrock and Detrital Zircon (U-Th)/(Pb-He) Dating, Mauléon Basin, Western Pyrenees written by Nicole Rita Hart and published by . This book was released on 2015 with total page 838 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the understanding of the structural, temporal, and thermal evolution of rifted continental margins has significantly evolved over the past several decades, critical outstanding questions remain, especially concerning the thermal evolution as well as the spatial and temporal intricacies of tectonically controlled sedimentation and sedimentary provenance during progressive rifting and hyper-extension. To constrain the proximal to distal tectonic, stratigraphic and thermal evolution of rifted continental margins, bedrock and detrital zircon (U-Th)/He (ZHe) and zircon U-Pb double dating techniques were applied to the Mauléon Basin of the western Pyrenees. This non-magmatic, asymmetric, hyper-extended rift basin formed during Early Cretaceous hyper-extension of Iberian lithosphere, as a result of lateral propagation of rifting in the Bay of Biscay, and experienced a limited magnitude of shortening during post-rift Pyrenean inversion. This resulted in the preservation of outcrops of sedimentary cover, upper and lower crustal sections, serpentinized lithospheric mantle, and the basic rift-relationships; making the Mauléon Basin an ideal locality to constrain rift-related processes during hyper-extension. Detrital zircon U-Pb analyses indicate that the proximal rift margin is primarily composed of pre-rift strata with Pan-African zircon U-Pb signatures and primary age peaks at ~615 Ma and ~1000 Ma. In contrast, the distal rift margin is composed of exhumed mid-lower crustal granulites, which have a similar Pan-African signature but with additional Variscan (Permian) overgrowths. Detrital zircon U-Pb analyses of syn- to post-rift strata indicate compartmentalized, local sourcing from the pre-rift strata in the proximal margin and the exhumed lower crust in the distal margin. Late syn- to post-rift strata show a shift to non-compartmentalized, regional sourcing from the proximal rift margin and hinterland. These observations are combined to present a sediment dispersal model for the progression of rifting. ZHe analyses shows preservation of two distinct age domains: an elevation-invariant age cluster at ~98 Ma, interpreted as rift-related cooling due to major exhumation along the SMD, and an elevation-invariant age cluster at ~50 Ma, interpreted as rapid cooling related to Pyrenean inversion. These results indicate the Mauléon Basin experienced early syn-rift heating prior to the exhumation of parts of the proximal domain to 180°C; these are the only localities that record rift-related timing. Based on thermochronometric modeling and burial estimates the syn-rift geothermal gradients in the necking domain were as high as ~80°C/km and ~80-100°C/km in the hyper-thinned domain. From the early syn-rift until Pyrenean inversion at ~50 Ma, most of the distal rift margin remained at temperatures 180°C. These observations of heating and high geothermal gradients are compared to geologic and numerical rifting models to give insight into preferred models for the rifting evolution of hyper-extended margins.
Book Synopsis Modelling Continental Rift Dynamics by : Sascha Brune
Download or read book Modelling Continental Rift Dynamics written by Sascha Brune and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continental rift systems open up unique possibilities to study the geodynamic system of our planet: geodynamic localization processes are imprinted in the morphology of the rift by governing the time-dependent activity of faults, the topographic evolution of the rift or by controlling whether a rift is symmetric or asymmetric. Since lithospheric necking localizes strain towards the rift centre, deformation structures of previous rift phases are often well preserved and passive margins, the end product of continental rifting, retain key information about the tectonic history from rift inception to continental rupture. Current understanding of continental rift evolution is based on combining observations from active rifts with data collected at rifted margins. Connecting these isolated data sets is often accomplished in a conceptual way and leaves room for subjective interpretation. Geodynamic forward models, however, have the potential to link individual data sets in a quantitative manner, using additional constraints from rock mechanics and rheology, which allows to transcend previous conceptual models of rift evolution. ...
Book Synopsis Recent Evolution and Seismicity of the Mediterranean Region by : E. Boschi
Download or read book Recent Evolution and Seismicity of the Mediterranean Region written by E. Boschi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mediterranean is one of the most studied regions of the world. In spite of this, a considerable spread of opinions exists about the geodynamic evolution and the present tectonic setting of this zone. The difficulty in recognizing the driving mechanisms of deformation is due to a large extent to the complex distribution in space and time of tectonic events, to the high number of parameters involved in this problem and to the scarce possibility of carrying out quantitative estimates of the deformation implied by the various geodynamic hypotheses. However, we think that a great deal of the present ambiguity could be removed if there were more frequent and open discussions among the scientists who are working on this problem. The meeting ofERICE was organized to provide an opportunity in this sense. In making this effort, we were prompted by the conviction that each step towards the understanding of the Mediterranean evolution is of basic importance both for its scientific consequences and for the possibleimplicationsfor society. It is well known, for instance, that the knowledge ofongoing tectonic processes in a given region and of their connection with seismic activity may lead to the recognition of middle long term precursors of strong earthquakes. The few cases of tentative earthquake prediction in the world occurred where information on large scale seismotectonic behavior was available. This led to identify the zones prone to dangerous shocks, where observations of short-term earthquake precursors were then concentrated.
Book Synopsis The South China Sea by : Pinxian Wang

Available in PDF, EPUB and Kindle. Book excerpt: Pinxian Wang and Qianyu Li The South China Sea (SCS) (Fig. 1. 1) offers a special attraction for Earth scientists world-wide because of its location and its well-preserved hemipelagic sediments. As the largest one of the marginal seas separating Asia from the Paci?c, the largest continent from the largest ocean, the SCS functions as a focal point in land-sea int- actions of the Earth system. Climatically, the SCS is located between the Western Paci?c Warm Pool, the centre of global heating at the sea level, and the Tibetan Plateau, the centre of heating at an altitude of 5,000m. Geomorphologically, the SCS lies to the east of the highest peak on earth, Zhumulangma or Everest in the Himalayas (8,848m elevation) and to the west of the deepest trench in the ocean, Philippine Trench (10,497m water depth) (Wang P. 2004). Biogeographically, the SCS belongs to the so-called “East Indies Triangle” where modern marine and terrestrial biodiversity reaches a global maximum (Briggs 1999). Among the major marginal sea basins from the west Paci?c, the SCS presents some of the best conditions for accumulating complete paleoclimatic records in its hemipelagic deposits. These records are favorable for high-resolution pa- oceanographic studies because of high sedimentation rates and good carbonate preservation. It may not be merely a coincidence that two cores from the southern 14 SCS were among the ?rst several cores in the world ocean used by AMS C dating for high-resolution stratigraphy (Andree et al. 1986; Broecker et al. 1988).
Book Synopsis The Sedimentary Basins of the United States and Canada by : Andrew Miall
Download or read book The Sedimentary Basins of the United States and Canada written by Andrew Miall and published by Elsevier. This book was released on 2008-12-03 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there have been rapid strides in our understanding of plate-tectonic processes, many developments in methods of basin analysis, and the accumulation of much new surface and subsurface geological and geophysical data. Projects such as COCORP (in the United States) and Lithoprobe (in Canada) have provided essential insights into the deep crustal structure of the continent. Synthesis of all the available information about North America’s geological regions has not been attempted systematically since the “Decade of North American Geology project undertaken by the Geological Society of America and the Geological Survey of Canada nearly twenty years ago. The book commences with a summary of the Phanerozoic geological history of the United States and Canada, illustrated with a suite of new paleogeographic maps, and tying in each of the subsequent regional chapters by the inclusion of numerous cross-references. This followed by a set of fifteen regional syntheses of the principal tectonic regions of the United States and Canada, focusing on the stratigraphic and tectonic history of the major sedimentary basins. Most of these chapters have been contributed by specialists, drawing on their own research, and providing interpretive summaries of a type not previously attempted.
