Understanding of secular evolution of the Earth system is based largely on the rock and
mineral archive preserved in the continental lithosphere. Based on the frequency and range …

The end of the Archean aeon (3.0–2.5 Ga) was a period of fundamental change in many
aspects of the geological record. In Archean cratons, this timespan is marked by a …

TTGs (tonalite–trondhjemite–granodiorite) are one of the archetypical lithologies of
Archaean cratons. Since their original description in the 1970s, they have been the subject …

This work examines the global distribution of Archaean and modern igneous rock's
compositions, without relying on preconceptions about the link between rock compositions …

Earth's continental crust is dominantly made of buoyant, felsic igneous material (granitoids),
that was ultimately extracted from the mantle as a result of Earth's differentiation. Since felsic …

Arc magmas originate in subduction zones as partial melts of the mantle, induced by
aqueous fluids/melts liberated by the subducted slab. Subsequently, they rise through and …

As a consequence of secular cooling of the Earth, there is generally no modern analog to
assist in understanding the tectonic style that may have operated in the Archean. Higher …

Subduction zones are tectonic expressions of convergent plate margins, where crustal rocks
descend into and interact with the overlying mantle wedge. They are the geodynamic system …

The geochemical signatures of subducting crust have been identified in various types of
mafic igneous rocks at convergent plate boundaries, where island arc basalts (IAB) and …

Until recently it was assumed that the Archaean continental crust (made of TTGs: tonalites,
trondhjemites, and granodiorites) was generated through partial melting of MORB-like …
