This analysis uncovers the role of tectonic realms in forming continental crust, highlighting implications for crustal evolution.
The nature of tectonic realms is a key to the origin of continental crust on early Earth. However, it is questionable to infer the composition of major elements in crustal rocks only from the composition of trace elements in zircon. Whereas non-plate tectonics was popular in generating the mafic crust in the Hadean, the operation of plate tectonics is necessary in transforming the mafic crust to the felsic crust in the Archean.
