Plate tectonics and the Archean Earth
If we accept that a critical condition for plate tectonics is the creation and maintenance of a
global network of narrow boundaries separating multiple plates, then to argue for plate …

No evidence for high-pressure melting of Earth's crust in the Archean
Much of the present-day volume of Earth's continental crust had formed by the end of the
Archean Eon, 2.5 billion years ago, through the conversion of basaltic (mafic) crust into sodic …

Formation and evolution of Archean continental crust: A thermodynamic–geochemical perspective of granitoids from the Tarim Craton, NW China
When and how continental crust formed and evolved to its current state is a fundamental
question regarding crust–mantle evolution and geodynamic regimes on the early Earth …

When crust comes of age: on the chemical evolution of Archaean, felsic continental crust by crustal drip tectonics
The secular evolution of the Earth's crust is marked by a profound change in average crustal
chemistry between 3.2 and 2.5 Ga. A key marker for this change is the transition from …

Generation of Archaean TTG gneisses through amphibole‐dominated fractionation
P Liou, J Guo - Journal of Geophysical Research: Solid Earth, 2019 - Wiley Online Library
The early continental crust is characterized by the tonalite‐trondhjemite‐granodiorite
gneisses (TTG) of Archaean terrains. There is a consensus that TTGs were formed by partial …
