Archean crust-mantle geodynamic regimes: A reviewShuwen Liu aHan Bao aGuozheng Sun bWei Wang cJinghao Fu dLei Gao cRongrong Guo eYalu Hu fGeosystems and Geoenvironment
Understanding the dominant crustal accretion model in any Archean craton is the key to understanding the dominant geodynamic process responsible for early crust formation during the Hadean (> 4.0 Ga) and Archaean (4.0–2.5 Ga). The continental crust has been proposed to have formed through eithe...

Earth—MantleEarth—CrustGeology, StructuralPossible geodynamic regimes that may have prevailed in the Archean are investigated by back-tracking the thermal history of Earth from the present-day conditions. If the temporal evolution of plate-tectonic convection is modulated by strong depleted lithosphere ...
enriched mantle which was variably contaminated by 3000-2900 Ma crust during its ascent.The Victoria terrane is unique amongst the Archean basement terranes in Greenland because it is dominated by 3500-3260 Ma crust. However, the Arctic basin contains detrital zircons of that age, and rocks of...
While a range of geodynamic regimes can explain the production of TTG magmas, the processes by which they separated from their source and acquired distinctive geochemical signatures remain uncertain. This limits our understanding of how the continental crust internally differentiates, which in turn ...

Geodynamic regimes responsible for the formation of Eoarchean-to-Mesoarchean continental crust may be investigated using numerical modeling in which deeper mantle processes are coupled with shallower processes responsible for the formation and modification of the crust. In an earlier study using a 2D ...
