Introduction to Geochronology
Geochronology is the field of science concerned with determining the ages of rocks and other stuff. 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 methdologies and applications however there is a focuss on the mainstream chronometers and the application of these to the quantification of geologic time.
