Thermal Signatures Of Heat Transfer Processes In The Earth S Crust

This book deals with the signatures left by geodynamic proceses in the temperature field of the Earth's crust. First, it introduces briefly the established, indirect methods for interpreting the present termperature field and methods for reconstructing the thermal fields of the geological past. Then the spatial and temporal scales that are relevant for heat transport processes are described. This problem is discussed both theoretically and on the basis of data from the German Continental Deep Drilling Program (KTB). The climate of the last 200 years and the postglacial warming in central Europe are reconstructed on the basis of two sets of temperature data from shallow and deep boreholes. This book is written for an audience at an advanced undergraduate or graduate level with an understanding of basic physical principles. It avoids particular terminology, and special terms are introduced.

This textbook on geophysics is a translated and revised editon from its third German edition Einfhrung in die Geophysik - Globale physikalische Felder und Prozesse in der Erde. Explaining the technical terminology, it introduces students and the interested scientific public to the physics of the Earth at an intermediate level. In doing so, it goes far beyond a purely phenomenological description, but systematically explains the physical principles of the processes and fields which affect the entire Earth: Its position in space; its internal structure; its age and that of its rocks; earthquakes and how they are used in exploring Earths structure; its shape, tides, and isostatic equilibrium; Earth's magnetic field, the geodynamo that generates it, and the interaction between the Earth's magnetosphere and the solar wind's plasma flow; the Earth's temperature field and heat transport processes in the core, mantle, and crust of the Earth and their role in driving the geodynamo and plate tectonics. All chapters begin with a brief historical outline describing the development of each branch of geophysics up to the recent past. Selected biographies illustrate the personal and social conditions under which groundbreaking results were achieved. Detailed mathematical derivations facilitate understanding. Exercises with worked-out results allow readers to test the gained understanding. A detailed appendix contains a wealth of useful additional information such as a geological time table, general reference data, conversion factors, the latest values of the natural constants, vector and tensor calculus, and two chapters on the basic equations of hydrodynamics and hydrothermics. The book addresses bachelor and master students of geophysics and general earth science, as well as students of physics, engineering, and environmental sciences with geophysics as a minor subject. The Author Christoph Clauser accepted the professorship for Applied Geophysics at RWTH Aachen University in Aachen, Germany in 2000. There, from 2007 until his retirement in 2018, he held the Chair of Applied Geophysics and Geothermal Energy at the E.ON Energy Research Center. He is an elected member of the National Academy of Sciences - German Academy of Sciences Leopoldina. He is specialized in geophysical aspects of reservoir engineering, particularly related to geothermal energy, hydrocarbons, and geological carbon dioxide sequestration.

This introduction to geothermal modeling deals with flow and heat transport processes in porous and fractured media related to geothermal energy applications. Following background coverage of geothermal resources and utilization in several countries, the basics of continuum mechanics for heat transport processes, as well as numerical methods for solving underlying governing equations are discussed. This examination forms the theoretical basis for five included step-by-step OpenGeoSys exercises, highlighting the most important computational areas within geothermal resource utilization, including heat diffusion, heat advection in porous and fractured media, and heat convection. The book concludes with an outlook on practical follow-up contributions investigating the numerical simulation of shallow and deep geothermal systems.

This book is dedicated to the numerical modeling of shallow geothermal systems. The utilization of shallow geothermal energy involves the integration of multiple Borehole Heat Exchangers (BHE) with Ground Source Heat Pump (GSHP) systems to provide heating and cooling. The modeling practices explained in this book can improve the efficiency of these increasingly common systems. The book begins by explaining the basic theory of heat transport processes in man-made as well as natural media. . These techniques are then applied to the simulation of borehole heat exchangers and their interaction with the surrounding soil. The numerical and analytical models are verified against analytical solutions and measured data from a Thermal Response Test, and finally, a real test site is analyzed through the model and discussed with regard to BHE and GSHP system design and optimization.

This book provides a general introduction to impact stratigraphy, with emphasis on the recognition of distal impact ejecta in the field, by focusing on the impactoclastic layers of the Umbria-Marche sequence in Central Italy, with an almost perfect stratigraphic record over the last 200 Million years. A general introduction to impact cratering and a discussion of distal ejecta and impact layers around the world is followed by a detailed description of the record of the impact of extraterrestrial bodies in sediments of the Umbria-Marche Apennines. The volume is of interest to a diverse audience in the geological and planetary sciences, ranging from (upper) undergraduate to research level. This book can also be used by students and researchers as a field guide to some of the most important Italian impact layers.

This volume is devoted to investigation of all aspects of heat-mass transfer processes at different scales and from various origins, as well as the formation and evolution of geological structures. These phenomena are linked to geophysical properties of rocks, geothermal resources, geothermics, fluid dynamics, stress-state of the lithosphere, deep geodynamics, plate tectonics, and seismicity, among others. The book consists of two main parts. The first concerns heat-mass transfer associated with natural and technogenic processes in the upper lithosphere. The second deals with geodynamics and seismicity. The collection of over 25 chapter from leading investigators in Russia is thus an important contribution to research on the lithosphere in connection with formation and evolution of geological structures; heat and mass transfer processes in the lithosphere and their connection with deep Earth geodynamics. Collects a range of research methodologies including application of modelling, seismic tomography, geological field works, geological-geophysical methods, and in situ measurements through instrumentation; Explains how a wide range of geological and geophysical phenomena arising in the Earth’s lithosphere can be investigated under the umbrella of a common approach to heat-mass transfer processes; Includes the latest research by more than 60 leading scientists from Russia.
