Book Description
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.

Book Description
This is a discount Black and white version. Some images may be unclear, please see BCCampus website for the digital version.This book was born out of a 2014 meeting of earth science educators representing most of the universities and colleges in British Columbia, and nurtured by a widely shared frustration that many students are not thriving in courses because textbooks have become too expensive for them to buy. But the real inspiration comes from a fascination for the spectacular geology of western Canada and the many decades that the author spent exploring this region along with colleagues, students, family, and friends. My goal has been to provide an accessible and comprehensive guide to the important topics of geology, richly illustrated with examples from western Canada. Although this text is intended to complement a typical first-year course in physical geology, its contents could be applied to numerous other related courses.

Book Description
The Earth's Crust and Mantle presents the deformations of the Earth's crust, which are attributed to mantle currents. This book explores the gravity observations, which give indications about the way in which the masses in the Earth are distributed. Comprised of five chapters, this book starts with an overview of the constitution of the various parts of the Earth and mentions the densities concerned. This text then discusses the thermal behavior of the Earth as well as examines the principle of isostasy and the readjustments of isostatic equilibrium. Other chapters examine the general effects of horizontal compression of the rigid crust and the fields of positive gravity anomalies. This book discusses as well the effects of active volcanicity, which is one source of disturbances of equilibrium of the Earth. The final chapter deals with the oceanic parts of the crust. This book is a valuable resource for geologists, geophysicists, physical geographers, and physical geodesists.

Book Description
The translation is a summary of complex data on the earth's crust and upper mantle. In the examination of the data on the various regions of the terrestrial globe (characteristics of the gravity, magnetic, seismic, thermal and electric fields of the earth) and the comparison between them and the structure of the crust, the author reveals the specific features of the different geological structures and determines the diagnostic significance of the geophysical data. Much attention is given to the crustal structure of the oceanic areas. A description of the general characteristics of the relief and the physical properties of the upper mantle is given in the last section of the book, where the physical map of the upper mantle is given in the last section of the book, where the physical map of the upper mantle is presented. In conclusion, a review is given of the projects of ultradeep scientific boring in the Pacific ocean, territory of the USSR, Japan and Canada. (Author).

Book Description
This breakthrough new book may help save countless lives and avoid enormous losses. It presents a methodology for using gas migration to predict earthquakes and explosive gas buildup. Using rigorous scientific investigation and documented worldwide case histories, this remarkable book presents compelling evidence showing that changes in gas rates, composition, and migration accompany the tectronic events preceding earthquakes and their associated seismic events, such as volcanoes and tsunamis. Because these gas parameters are detectable and measurable, they provide an early warning of seismic activity.Gas Migration is the first book to accumulate, analyze and apply the interdisciplinary knowledge on gas migration and detail its connection to tectronic, seismic, and geologic phenomena. It combines geological, geochemical, geophysical, seismological, and petroleum engineering insights to demonstrate how gas migration and its associated phenomena can be used in earthquake and environmental geohazard identification and prediction. Topics include-·Tectonics and Earthquakes·Gas Migration at Plate Boundaries·Surface Soil-Gas Surveys·Faults and Petroleum Reservoirs·Earthquake Precursors·Whispering Gases·Paths and Mechanics of Gas Migration·Subsidence, Gas Migration, and Seismic Activity·And much moreWith this information, environmental specialists, civil engineers, petroleum geologists, seismologists, and urban planners now have a new and powerful conceptual basis and tool for understanding and perhaps even predicting gas explosions and earthquakes.

Book Description
Constitution of the Earth's Interior discusses the physical and evolutionary principles connecting various elements of the knowledge about structure and dynamics of the Earth's interior. This work is divided into eight chapters that primarily focus on the physical, chemical, and petrological state. This text contains general data on a general stationary model, which is described by equations of state combining the basic parameters, including pressure, temperature, density, gravity acceleration, and mineral composition within the Earth's interior. Considerable chapters concern the chemical and petrological composition of the matter in the Earth's interior. The remaining chapters describe models containing inhomogeneities used to illustrate processes connected with phase transitions. This book will be of great value to geologists, physicists, and researchers.

Book Description
30% discount for members of The Mineralogical Society of Britain and Ireland The movement of fluids through rocks has profound consequences for the transport of heat and matter within the Earth. Recently, considerable effort has been expended in determining the mechanisms and pathways of geological fluid flow, with much of this research concentrated on the effects of deformation on rock permeability. Although it is well known that fractures can act as conduits for fluid transport (as evidenced by abundant mineral-fined veins and sheet-like igneous intrusions), the role of ductile deformation has now been recognised as an important factor controlling rock permeability in environments as diverse as the mantle, the deep crust, and shallow crustal shear zones. This book brings together review and research articles united by the theme of deformation-enhanced fluid transport, with the aim of emphasizing the many common roots of this important body of work. Subjects covered include the movement of basaltic melts in the mantle; the segregation, ascent and emplacement of granitic melts in the crust; the flow through the crust of volatile fluids produced during metamorphic events; and the movement of aqueous fluids through fractured rocks near the Earth's surface. Deformation-Enhanced Fluid Transport in the Earth's Crust and Mantle will appeal to all geoscientists interested in the movement of fluids through the Earth. It will prove an invaluable reference work for those working in the field and will provide i useful introduction to this wide-ranging and rapidly evolving area of research for non-specialists.
