Geochronology is the field of science concerned with determining the ages of geologic materials from granite and mudstone to fossils and meteorites. In this book we attempt to outline the basic principles used for the quantification of geological time focusing on the radio-isotopic dating techniques. We are attempting to be inclusive about the methodologies and applications however there is a focus on the mainstream chronometers and the application of these to the quantification of geologic time.
