This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Andes Mountains are a culmination of smaller mountain ranges that form the longest mountain chain in the world, accommodating convergence and the subduction of the Nazca Plate under the South American Plate since the Late Jurassic. Subduction along the Andean margin varies from normal-dipping to flat-slab subduction, with flat-slab segments commonly characterized by crustal thicknesses upwards of ~70 km. The Peruvian segment is of particular interest, as magmatic arcs in this region show an eastward younging trend and active extension along the western margin of the youngest plutonic feature, the Cordillera Blanca batholith. Extension along this margin is limited to high elevations and occurs along an active low-angle normal detachment fault striking parallel to the trend of the ~200-km-long Cordillera Blanca mountain range, which hosts numerous peaks > 6000 m. The detachment exhumes a mylonitic shear zone of deformed batholith rocks. Tectonic fabrics suggest that 1) extension along the fault is parallel to the direction of plate convergence and regional crustal shortening, and 2) the shear zone crossed the brittle-ductile transition while it was actively deforming during exhumation. These conditions make for a unique setting in which to study the mid-crustal brittle-ductile-transition, and strain localization in a syn-convergent extensional setting where the regional principal stresses are known. This project characterizes deformation of the exhumed shear zone using detailed kinematic analyses, deformation temperature analyses, paleopiezometry, and geochemistry. From this work, a crustal strength profiles for the Cordillera Blanca has been constructed, providing a model for the rheologic evolution of this particular region and contributing to the structural community's understanding of the rheologic conditions that allow for convergence-parallel extension in the mid-crust.

This book was released on 2008-01-01 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Franciscan subduction complex formed a long-lived accretionary wedge of Late Jurassic through Oligocene age that fringed the western edge of the North American Cordillera. This volume summarizes absolute finite-strain data from the Franciscan subduction complex and brittle strain data from important faults in and above this complex. Because the Franciscan is generally considered a prototypical sediment-rich subduction complex, its tectonic evolution is important for understanding convergent plate margins, and the results outlined in this volume may have broad implications for other subduction-zone settings."--pub. desc.

Available in PDF, EPUB and Kindle. Book excerpt: The Geological Survey's 1907 Memoir 'The Geological Structure of the North-West Highlands of Scotland' outlined many of the principles of field-based structural and tectonic analysis that have subsequently guided generations of geologists working in other mountain belts, both ancient and modern. These 32 papers celebrate the centenary of the 1907 Memoir by placing the original findings in both historical and modern contexts, and juxtaposing them against present-day studies of deformation processes operating not only in the NW Highlands, but also in other mountain belts.

Available in PDF, EPUB and Kindle. Book excerpt: The motion and deformation of rocks are processes of fundamental importance in shaping the Earth, from outer crustal layers to the deep mantle. Reconstructions of the evolution of the Earth therefore require detailed knowledge of the geometry of deformation structures and their relative timing, of the motions leading to deformation structures and of the mechanisms governing these motions. This volume contains a collection of 22 papers on field, experimental and theoretical studies that add to our knowledge of these processes.

This book was released on 2022 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work the central area of Corsica island was studied in order to reconstruct the tectono-metamorphic history of the continental and oceanic high pressure units that occupy the structurally deeper levels of the tectonic stacking of Alpine Corsica and their stratigraphic and structural relationship with the European margin (Hercynian Corsica). The study includes the geological mapping, the mesoscale and microscale structural analysis, the acquisition of chemical analyzes and micromaps with the microprobe, thermobarometric estimation through specific methodologies for metapelites, U-Th-Pb dating of zircons and allanites. The results obtained allows to reconstruct the geodynamic model of this sector of the Alpine belt from the Permian to the Burdigalian.

Available in PDF, EPUB and Kindle. Book excerpt: This collection of research and review papers addresses the question of structural evolution during deformation to high strains and the physical properties of rocks that have been affected by high-strain zones. The discussions range from natural examples at outcrop to microscopic studies. They include experiments and numerical models based on the active processes in high-strain zones as well as studies on the physical properties of highly strained rocks in the field and laboratory. Specific questions addressed include magnetotelluric imaging of faults, magnetic fabrics, fabric development, seismic properties of highly strained rocks, change of rheology with strain, influence of melt on the localization of deformation, the relationship between deformation and metamorphism as well as new methods in the analysis of deformation. The book is aimed at an interdisciplinary group of readers interested in the effects of high strain in rocks.

Download or read book Analogue and Numerical Modelling of Crustal scale Processes written by Susanne Janita Henriët Buiter and published by Geological Society of London. This book was released on 2006 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crust of the Earth records the deformational processes of the inner Earth and the influence of the overlying atmosphere. The state of the Earth's crust at any time is therefore the result of internal and external processes, which occur on different time and spatial scales. In recent years important steps forward in the understanding of such complex processes have been made by integrating theory and observations with experimental and computer models. This volume presents state-of-the-art analogue and numerical models of processes that alter the Earth's crust. It shows the application of models in a broad range of geological problems with careful documentation of the modelling approach used. This volume contains contributions on analogue and numerical sandbox models, models of orogenic processes, models of sedimentary basins, models of surface processes and deformation, and models of faults and fluid flow.
