The evolution of the continental crust and the onset of plate tectonics
The Earth is the only known planet where plate tectonics is active, and different studies have
concluded that plate tectonics commenced at times from the early Hadean to 700 Ma. Many …

A change in the geodynamics of continental growth 3 billion years ago
Models for the growth of continental crust rely on knowing the balance between the
generation of new crust and the reworking of old crust throughout Earth's history. The …

Crustal melting vs. fractionation of basaltic magmas: Part 1, granites and paradigms
Granitoids are a major component of the continental crust. They play a pivotal role in its
evolution, either by adding new material (continental growth), or by reworking older …
