About this book
As in the original edition of 1988, this book covers the principles and practice of argon isotopic dating, a technique that has been used to determine the numerical age of the Earth. The greater precision of the 40Ar/39Ar method allows scientists to test smaller geological samples than its precursor, the K-Ar method, which required a comparison of different elements. The new edition will incorporate new developments made in 40Ar/39Ar application over the last decade, made possible by advances in lasers and mass spectrometry.

"The coverage of the book is broad and detailed, and the book contains a great deal of information on a variety of related topics. Many examples of studies on specific samples are used as illustrations throughout the book, almost all involving terrestrial materials. The book uses many tables, figures, and equations to illustrate concepts. it also contains 26 pages of references and a seven-page index. It is by far the most extensive treatment of the 40Ar/39Ar dating technique and its applications of which I am aware. Every laboratory performing radiometric dating may wish to have a copy." -- Donald D. Bogard, Meteoritics & Planetary Science, 36, 2001
