Geochronology and Thermochronology by the 40Ar/39Ar Method
"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
