The spectrum of physical and chemical dating methods now covers the entire range of Earth history. But there are so many methods that it is becoming increasingly difficult to select those that are appropriate for solving a specific problem. The objective of this book is to cover the whole spectrum of methods and to give examples of their applications. Thus it is addressed to everybody interested in the application of physical and chemical dating methods to the geosciences and archeology. It is especially valuable as a concise, but comprehensive reference for students and practitioners.

With the growing recognition during the last two centuries that the Earth has an immense age and processes over long periods of time have changed the morphology and composition of the Earth's crust, geologists have become increasingly interested in determination of absolute ages. A rela tive geochronology was established on the basis of the lithostratigraphic and biostratigraphic principles developed during the last century. With the discovery of radioactivity, the basis for a new geoscientific discipline - geochronology - was established (Rutherford 1906). It is the study of geological time, based mainly on the time signatures provided by the isotopic composition in geologic materials. The isotopic signature in a rock yields more information than that provided by the geochemical signature alone because it reflects the origin and history of the element in the rock. The aim of geochronology is to calibrate and standardize chronostrati graphic scales, to develop geological time scales that have a sensitive or at least useful resolution in order to place the geological events in the correct chronological order, and to assign their proper time spans. In practice, the application of geochronology is much wider because the data in the "natural archives" often provide information on the origin, genesis, and history of the materials. This, of course, requires an understanding of the geochemical behavior of the substances involved.

Download and read online ebook Encyclopedia of Solid Earth Geophysics write by Harsh Gupta. This book was released on 2011-06-29. Encyclopedia of Solid Earth Geophysics available in PDF, EPUB and Kindle. The past few decades have witnessed the growth of the Earth Sciences in the pursuit of knowledge and understanding of the planet that we live on. This development addresses the challenging endeavor to enrich human lives with the bounties of Nature as well as to preserve the planet for the generations to come. Solid Earth Geophysics aspires to define and quantify the internal structure and processes of the Earth in terms of the principles of physics and forms the intrinsic framework, which other allied disciplines utilize for more specific investigations. The first edition of the Encyclopedia of Solid Earth Geophysics was published in 1989 by Van Nostrand Reinhold publishing company. More than two decades later, this new volume, edited by Prof. Harsh K. Gupta, represents a thoroughly revised and expanded reference work. It brings together more than 200 articles covering established and new concepts of Geophysics across the various sub-disciplines such as Gravity, Geodesy, Geomagnetism, Seismology, Seismics, Deep Earth Processes, Plate Tectonics, Thermal Domains, Computational Methods, etc. in a systematic and consistent format and standard. It is an authoritative and current reference source with extraordinary width of scope. It draws its unique strength from the expert contributions of editors and authors across the globe. It is designed to serve as a valuable and cherished source of information for current and future generations of professionals.

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.

Download and read online ebook Encyclopedia of Lakes and Reservoirs write by Lars Bengtsson. This book was released on 2012-06-25. Encyclopedia of Lakes and Reservoirs available in PDF, EPUB and Kindle. Lakes and reservoirs hold about 90% of the world's surface fresh water, but overuse, water withdrawal and pollution of these bodies puts some one billion people at risk. The Encyclopedia of Lakes and Reservoirs reviews the physical, chemical and ecological characteristics of lakes and reservoirs, and describes their uses and environmental state trends in different parts of the world. Superbly illustrated throughout, it includes some 200 entries in a range of topics, including acidification, artificialisation, canals, climate change effects, dams, dew ponds, drainage, eutrofication, evaporation, fisheries, hydro-electric power, nutrients, organic pollution, paleolimnology, reservoir capacities and depths, sedimentation, water resources and more.
