Much of the continental crust exposed within the continental interiors consists of metamorphosed rocks. These rocks can be conveniently grouped in terms of the age of metamorphism as recorded by common40 Ar/39 Ar geochronometers such as K-feldspar, biotite, muscovite, and hornblende. Such a division illustrates the evolution of the continental crust through time from the early Archean exposed in the continental interiors to the youngest metamorphic rocks found in the rapidly exhumed rocks at the continental margins. Metamorphic rocks are important in that they often constitute the only record of evolution of the continental crust and bear evidence for tectonic processes in the geological past.
