Available in PDF, EPUB and Kindle. Book excerpt: "Two hundred and eight potassium-argon age determinations carried out on Canadian rocks and minerals are reported. Each age determination is accompanied by a description of the rock and mineral concentrate used: brief interpretative comments regarding the geological significance of each age are also provided where possible. The experimental procedures employed are described in brief outline and the constants used in the calculation of ages are listed. Two geological time-scales are reproduced in tabular form for ready reference and an index of all Geological Survey of Canada K-Ar age determinations published in this format has been prepared using NTS quadrangles as the primary reference." --

Download or read book The Upper Mantle written by A. R. Ritsema and published by Elsevier. This book was released on 2013-10-22 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developments in Geotectonics, 4: The Upper Mantle focuses on the upper mantle and its influence on the development of the earth's crust, including history of the moon and other planets and volcanology. The selection first offers information on the origin of the earth, including ideas on the formation process of the terrestrial planets, condensation of dust particles, nature of the earth's core, thermal history of the earth, and fractionation of iron in the terrestrial planets. The text then ponders on the beginning of continental evolution, as well as the oldest rocks of the earth's crust, thermal history of the moon, and early history of the other planets. The text elaborates on magmatic activity as the major process in the chemical evolution of the earth's crust and mantle; trends in the evolution of continents; progress and problems in volcanology; and pressure and temperature conditions and tectonic significance of regional and ocean-floor metamorphism. The manuscript also takes a look at the state of mantle minerals, melting temperatures in the earth's mantle, and geomagnetic induction studies and the electrical state of the upper mantle. The publication is a dependable reference for readers interested in the study of the upper mantle.
