Available in PDF, EPUB and Kindle. Book excerpt: A multidisciplinary perspective on the dynamic processes occurring in Earth's mantle The convective motion of material in Earth's mantle, powered by heat from the deep interior of our planet, drives plate tectonics at the surface, generating earthquakes and volcanic activity. It shapes our familiar surface landscapes, and also stabilizes the oceans and atmosphere on geologic timescales. Mantle Convection and Surface Expressions brings together perspectives from observational geophysics, numerical modelling, geochemistry, and mineral physics to build a holistic picture of the deep Earth. It explores the dynamic processes occurring in the mantle as well as the associated heat and material cycles. Volume highlights include: Perspectives from different scientific disciplines with an emphasis on exploring synergies Current state of the mantle, its physical properties, compositional structure, and dynamic evolution Transport of heat and material through the mantle as constrained by geophysical observations, geochemical data and geodynamic model predictions Surface expressions of mantle dynamics and its control on planetary evolution and habitability The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Download or read book The Earth's Heterogeneous Mantle written by Amir Khan and published by Springer. This book was released on 2015-04-28 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights and discusses recent developments that have contributed to an improved understanding of observed mantle heterogeneities and their relation to the thermo-chemical state of Earth's mantle, which ultimately holds the key to unlocking the secrets of the evolution of our planet. This series of topical reviews and original contributions address 4 themes. Theme 1 covers topics in geophysics, including global and regional seismic tomography, electrical conductivity and seismic imaging of mantle discontinuities and heterogeneities in the upper mantle, transition zone and lower mantle. Theme 2 addresses geochemical views of the mantle including lithospheric evolution from analysis of mantle xenoliths, composition of the deep Earth and the effect of water on subduction-zone processes. Theme 3 discusses geodynamical perspectives on the global thermo-chemical structure of the deep mantle. Theme 4 covers application of mineral physics data and phase equilibrium computations to infer the regional-scale thermo-chemical structure of the mantle.

This book was released on 2007 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: We combine large data sets of surface-wave phase anomalies, long-period waveforms, and body-wave travel times in order to provide new constraints on the anisotropic shear-wave velocity structure of the Earth's mantle. The waveform inversion is performed using a new and more accurate method developed to correct seismograms for non-linear crustal effects. Starting with an isotropic spherically symmetric earth model, we build a new one-dimensional, transversely isotropic reference model by independently constraining variations in five elastic parameters and density. Using this new reference model, we invert the data for a whole-mantle model of shear-wave velocity and investigate lateral anisotropic variations at all depths in the mantle. Finally, we develop a technique that allows us to calculate a high-resolution tomographic model of a specific region as a perturbation with respect to the low-resolution global model, and implement this technique to study the structure beneath Eurasia.

Download or read book Seismology and Structure of the Earth written by Barbara Romanowicz and published by Elsevier. This book was released on 2010-04-20 with total page 873 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treatise on Geophysics: Seismology and Structure of the Earth, Volume 1, provides a comprehensive review of the state of knowledge on the Earths structure and earthquakes. It addresses various aspects of structural seismology and its applications to other fields of Earth sciences. The book is organized into four parts. The first part principally covers theoretical developments and seismic data analysis techniques from the end of the nineteenth century until the present, with the main emphasis on the development of instrumentation and its deployment. The second part reviews the status of knowledge on the structure of the Earths shallow layers, starting with a global review of the Earth's crustal structure. The third part focuses on the Earth's deep structure, divided into its main units: the upper mantle, the transition zone and upper-mantle discontinuities, the D region at the base of the mantle, and the Earth's core. The fourth part comprises two chapters which discuss constraints on Earth structure from fields other than seismology: mineral physics and geodynamics. - Self-contained volume starts with an overview of the subject then explores each topic with in depth detail - Extensive reference lists and cross references with other volumes to facilitate further research - Full-color figures and tables support the text and aid in understanding - Content suited for both the expert and non-expert

Download or read book Shear-wave Velocity Structure in the Crust and Upper Mantle Beneath the Central Tien Shan from Surface-wave Tomography written by Arianna Lisi and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tien Shan in central Asia is the world's largest and most active intracontinental orogen, with a shortening rate of 20 mm/yr. Its tectonic reactivation started 20-25 Ma, which has been attributed to the India-Eurasia collision. Despite many geological and geophysical studies in the Tien Shan, the mechanism of building this intraplate mountain belt remains debatable. Here I constructed a 3-D shear-wave velocity model beneath the central Tien Shan using Rayleigh-wave data recorded at 41 broadband stations in the study area. Phase velocities are obtained from the two-plane-wave inversion at periods of 20 to 133 s and from the ambient noise tomography at 8 to 30 s and are used to determine shear-wave velocity variations beneath the central Tien Shan. Low-velocity anomalies in the upper crust correlate well with thick sediments in the Tarim basin, Lake Issky Kul, and Naryn basin. The lowest velocity in the lower crust is beneath the central high range, suggesting a weak crust. A fast velocity anomaly is imaged beneath the northern Tarim block to the Naryn basin from 30 to 70 km, indicating the underthrusting of the Tarim basement. These observations support that the formation of the Tien Shan is due to both a strong Tarim and a weak Tien Shan lithosphere. A circular slow anomaly to 150 km depth is observed beneath the Naryn basin in the west, while the eastern central Tien Shan is characterized by a fast anomaly. In addition, the fast anomaly that represents the Tarim lithosphere stops sharply at the Naryn basin but continues and deepens under the eastern part. Such variation of velocity structure along the Tien Shan strike implies that the western and eastern range is undergoing different mountain building procedures. A favorable interpretation is that the subducted Tarim lithosphere was delaminated in the west and the slow anomaly there reflects the hot asthenosphere. In contrast, the Tarim lithosphere is still present beneath the eastern part, which may be removed in the future to develop the scenario as in the western part.
