Geochronology and Thermochronology by the 40ar/39ar Method

• Gebundenes Buch

Produktbeschreibung

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.

Argon isotopic dating is one of the most important techniques for estimating the ages of rocks and can be used on very small samples. It has been used to assign reliable ages to the Earth and numerous meteorites. This second edition covers the standard principles and methods and incorporates many of new developments from the last decade. It covers the basis of the method, technical aspects, data presentation, diffusion theory, thermochronology, and many applications and case studies.
