Electromagnetic Geothermometry Excerpt :

Electromagnetic Geothermometry explores, presents and explains the new technique of temperature estimation within the Earth’s interior; the Electromagnetic technique will identify zones of geothermal anomalies and thus provides locations for deep drilling. This book includes many case studies from geothermal areas such as Travale (Italy), Soultz-sous-Forêts (France) and Hengill (Iceland), allowing the author and reader to draw conclusions regarding the dominating heat transfer mechanisms, location of its sources and to constrain the locations for drilling of the new boreholes. Covering a topic that so far has very little coverage (due to its newness) Electromagnetic Geothermometry presents ground breaking information on the interpretation of MT signals. And as such, is similar to the work that was done to develop new generations of seismic inversion methods that have since come to dominate the oil industry. Up until now geophysical methods have had difficulty resolving temperature differences which have been critical in the understanding of location and magnitude of geothermal resources Authored by the world’s foremost geothermometry experts who combined have more than 40 years of experience on the subject Presents case studies, allowing the author and reader to draw conclusions regarding the dominating heat transfer mechanisms, location of its sources and to constrain the locations for drilling of the new boreholes Provides important information on the constraints for drilling of new exploration boreholes Describes techniques that will dramatically decrease the costs associated with exploration drilling Includes information to help the reader improve the accuracy of the temperature estimations in the interwell space as well as far beneath boreholes

Geoelectromagnetic Investigation of the Earth s Crust and Mantle Excerpt :

Electrical conductivity is a parameter which characterizes composition and physical state of the Earth's interior. Studies of the state equations of solids at high temperature and pressure indicate that there is a close relation be tween the electrical conductivity of rocks and temperature. Therefore, measurements of deep conductivity can provide knowledge of the present state and temperature of the Earth's crust and upper mantle matter. Infor mation about the temperature of the Earth's interior in the remote past is derived from heat flow data. Experimental investigation of water-containing rocks has revealed a pronounced increase of electrical conductivity in the temperature range D from 500 to 700 DC which may be attributed to the beginning of fractional melting. Hence, anomalies of electrical conductivity may be helpful in identitying zones of melting and dehydration. The studies of these zones are perspective in the scientific research of the mobile areas of the Earth's crust and upper mantle where tectonic movements, processes ofthe region al metamorphism and of forming mineral deposits are most intensive. Thus, in the whole set of research on physics of the Earth the studies of electrical conductivity of deep-seated rocks appear, beyond doubt, very important.

Induction Soundings of the Earth s Mantle Excerpt :

At the heart of this book is the generalized theoretical approach that is applied to investigate the geoelectrical structure of the Earth’s mantle. It also analyzes the results of regional and global induction sounding of the Earth’s mantle and compares them with the results obtained by other geophysical methods. The generalized theoretical approach employs the Induction Law as a basis for identifying extended relations between magnetic field components, including their plane divergence, impedances and spatial derivatives. The estimations of impedance values and spatial derivatives are performed using the theory of stochastic processes. The book also considers the external sources of magnetic fields used for sounding the Earths mantle from the modern theory perspective, as well as the problem of coincidence of magneto-variation and magnetotelluric methods. Further, it discusses secular variations in the Earth’s resistance caused by non-induction sources, factors that are correlated with the number of earthquakes in the region and shifted in time with global indexes. It is a valuable resource for scientists applying deep induction soundings or interested in the structures of and processes in the Earth’s interior.

Physics and Chemistry of the Earth s Interior Excerpt :

The Indian National Science Academy was established in January 1935 with the objective of promoting science in India and harnessing scientific knowledge for the cause of humanity and national welfare. In 1968 it was designated as the adhering organisation in India to the International Council for Scientific Union (ICSU) on behalf of the Government of India. Over the years, the Academy has published a number of journals, volumes, biographical memoirs, etc. The year 2009–2010 will be specially celebrated to mark the Platinum Jubilee of the Academy. Many programmes are planned in different centres in India on this occasion. In addition, the Academy has decided to publish a number of special volumes on different s- jects ranging from earth sciences to life sciences. This volume is on Physics and Chemistry of the Earth’s Interior. One of the main objectives of geophysicists is to establish the internal structure of the earth as revealed by seismic tomography. It is also their primary goal to correlate geophy- cal data to reveal thermal and chemical state of the crust, mantle and core of the earth. In - der to interpret seismic velocities and associated density and elastic properties in terms of mineralogical and petrological models of the earth’s interior, thermodynamic and hi- pressure temperature data from mineral physics are essential. With the advent of different types of multi-anvil and laser-heated diamond anvil equipment, it is now possible to simulate conditions prevalent even in the lower mantle and core of the earth.

The conductivity can be determined from the amount of shift between the field data and the theoretical curve. A detailed description of the curve matching procedure is found in a text by Keller and Frischknecht (1966). The curve matching procedure, though used, has several disadvantages. Measurements must be made over a diagnostic portion of the theoretical curve, one in which there is some curvature, so that the amount of shift required to make a match can be determined uniquely. This means that the approximate conductivity of the earth must be known when measurements are made. Secondly, determination of a single value of conductivity requires measurements made over a wide range of frequencies. This would appear to be wasteful of data, inasmuch as the equations indicate that a single measurement at a single frequency should be enough to de termine conductivity.
