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 …

Deep formation of Earth's earliest continental crust consistent with subduction
About four billion years ago, Earth's outer layer is thought to have been composed mostly of
a 25-to 50-km-thick basaltic crust that differentiated to form the oldest stable continental …

Granitoids of the tonalite–trondhjemite–granodiorite (TTG) series dominate Earth's earliest
continental crust. The geochemical diversity of TTGs is ascribed to several possible …

Origin, accretion, and reworking of continents
The continental crust is unique to the Earth in the solar system, and controversies remain
regarding its origin, accretion and reworking of continents. The plate tectonics theory has …

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 …

Remnants of Eoarchean continental crust derived from a subducted proto-arc
Eoarchean [3.6 to 4.0 billion years ago (Ga)] tonalite-trondhjemite-granodiorite (TTG) is the
major component of Earth's oldest remnant continental crust, thereby holding the key to …

TTG generation by fluid-fluxed crustal melting: Direct evidence from the Proterozoic Georgetown Inlier, NE Australia
Abstract Across the Archaean to Proterozoic transition, the composition of newly-formed
felsic continental crust changed from tonalite–trondhjemite–granodiorite (TTG) to calc …

Earth's oldest stable crust in the Pilbara Craton formed by cyclic gravitational overturns
During the early Archaean, the Earth was too hot to sustain rigid lithospheric plates subject
to Wilson Cycle-style plate tectonics. Yet by that time, up to 50% of the present-day …

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 …
