About the Book: Geochronology and Thermochronology
The nature of thermochronologic and geochronologic questions are also
frequently basically different. The formation age of minerals is normally
irrelevant in thermochronology, whilst rates of processes are frequently of
dominant interest. Geochronology has demonstrated key to our present-day
understanding of the dynamic procedures that have shaped the Earth. The increase
of high-precision geochronology worldwide in the last 15 years, in particular
that generated by sensitive high-resolution ion microprobe (SHRIMP), has
transformed the geological communitys view of the Proterozoic Eon, and the
implicit assumptions that form the basis of most work conducted on rocks of that
age. Geologic research and mapping requires the
