Geothermics

This book, now in its second edition, offers a comprehensive and modern treatment on the background knowledge of heat transfer processes in the lithosphere. In the light of the success of the first edition, several chapters of the book have been revised and the book has been enriched with a new chapter on geothermal methods used for the inference of past climate changes.The book starts with a brief review of global tectonics and of the structure of the crust and upper mantle. Then the theory of heat conduction as well as the thermal properties and the methods for the determination of thermal conductivity and radiogenic heat are introduced. Subsequently the geothermal flow and the thermal state of the lithosphere and deep interior are analyzed. The formation, upwelling mechanisms, solidification and cooling of magmas, which can be a fundamental heat source in many geothermal systems, are reviewed. Analytical methods used for gaining information on heat and groundwater flow from the analyses of temperature depth data are also covered. Data and practical examples are supplied to facilitate the understanding of the different topics.The book is intended for Earth science graduate students and researchers.

Autorentext

Vincenzo Pasquale worked as a Researcher for the National Research Council (CNR) from 1972 to 1979 and as Assistant Professor of Physics of the Earth for the Geodetic and Geophysical Institute of the University of Genoa, Italy. Since 1980, he is a Professor of Solid Earth Geophysics at the University of Genoa. He has authored more than 250 scientific papers, 100 of which were published in leading international journals. The first ten years of his research were devoted mainly to seismology. In 1980s, he began his studies on the Earth's rheology and thermal field. He has been responsible of a numerous research projects. He is a member of national and international scientific associations and referee of international journals. Massimo Verdoya received his MSc in Geological Sciences in 1985, and in 1992 his Ph.D. degree in Geophysics at the University of Genoa, Italy. From 1993 to 2014 he worked as a Researcher in Solid Earth Geophysics and thereafter as Associate Professor at the University of Genoa. His fields of interest are: thermal modeling of lithospheric geodynamical processes, applied geothermics, analytical and numerical simulations of heat and groundwater transfer (with special reference to hydrothermal reservoirs), determinations of thermo-physical properties of rocks and soils (thermal conductivity and diffusivity), past climate change inferred from underground temperatures. He is vice-chairman of the International Heat Flow Commission of the IASPEI (International Association of Seismology and Physics of the Earth Interior) and member of the board of directors of the International Geothermal Association. Paolo Chiozzi received his MSc in Earth Sciences in 1989 and his Ph.D. in Geophysics at the University of Genoa (Italy) in 1995. Since 1996, he works as a Research Fellow at the University of Genoa on several projects encompassing a wide range of geodynamic and geothermic problems. Hisresearch is focused on the relationships between the thermal structure and the deformation processes within the lithosphere. He has developed techniques of spectral analysis of magnetic data to obtain information on the deep magnetic boundary and their relation with the temperature distribution and the Curie point. Moreover, his activity is addressed to the determination of thermo-physical properties and natural radioactivity of rocks and soils and underground temperatures. He has published more than 50 papers in international journals.
