Geochronology and thermochronology combine geochemistry, nuclear reactions, and technology to probe the history and dynamics of Earth and planetary processes.
Geology is, in essence, the history of the Earth, and any history depends on dates and rates. Geochronology supplies these. A new book, Geochronology and Thermochronology, recently published by the American Geophysical Union, presents the current state of this science including its concepts, approaches, methods, and applications. Here, the authors answer some questions about the science of geochronology and its relevance, and describe how this field has evolved. Read more.
