Physics and Chemistry of the Earth, Volume VI is a collection of research papers that present geochemical and geophysical investigations of the constitution and history of the earth; geological phenomena; and oil and ore formation. The book is composed of seven chapters written by different authors who are experts in the fields of geophysics and geochemistry. It covers the description of the structure and composition of the earth''s mantle; a survey of the developments in the study of seismic surface waves; and model experiments of tectonic processes. Articles on the application of trace element data to problems in petrology and factors in the distribution of the trace elements during the crystallization of magmas, both important topics on mining, are presented as well. Geologists, geophysicists, geochemists, and students of petrology and mineralogy will find this book a good source of information.

Physics and Chemistry of the Earth, Volume VII focuses on three topics—orogenic fold-belts and a hypothesis of earth evolution; earthquake energy and magnitude; and meteoritic, solar, and terrestrial rare-earth distributions. This book consists of three chapters. Chapter 1 examines features of the distribution and history of the Precambrian fold-belts in relation to the theory of continental drift. The two kinds of information obtained from seismograph records—time readings and amplitude readings that provide information on the total seismic wave energy released in earthquakes—are elaborated in Chapter 2. Chapter 3 discusses the meteoritic and terrestrial matter in rare earth elements (REE). This publication is a good reference to students and researchers conducting work on earth science.

Continental Drift brings together within one volume a discussion of the geophysical evidence relating to horizontal movements in the earth''s crust in its widest sense. This is not the time for a reappraisal of the work of German meteorologist Alfred Wegener, but it is hoped that this volume will stimulate a serious interest in a subject formerly considered by many earth scientists as already closed. The book contains 12 chapters and begins with a discussion of paleomagnetic evidence for continental drift and its geophysical cause. This is followed by separate chapters on of paleoclimatic evidence on the paleomagnetic latitudes given by paleomagnetism; studies of earthquake mechanism; movements on major transcurrent faults; and magnetic evidence for horizontal displacements in the floor of the Pacific Ocean. Subsequent chapters deal with thermal convection in the earth''s mantle; the theory of convection in spherical shells and its application to the problem of thermal convection in the earth''s mantle; mountain-building hypotheses; and investigations of the deep-sea floor.
