An outstanding feature of the Archaean Eon is that it was a time of major production and preservation of continental lithosphere. Here I review the geological, geochemical and basic …
The 3.7–3.8 Ga Isua greenstone belt of southwest Greenland is characterized by variably metamorphosed, metasomatised and deformed lithotectonic successions of volcanic and …

There is no consensus on the processes responsible for near-coeval formation of Archaean continental crust (dominantly tonalite–trondhjemite–granodiorite: TTG), greenstone belts …

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 …

High-P/T metamorphic belts were classified into types A and B according to their protoliths. The A-type (collision-type) blueschists possess passive-margin protoliths characterized by …

The granite-and-greenstone terrains that dominate upper crust formed from about 3.6 to about 2.6 Ga, and record magmatic and tectonic processes very different from those of a …
I review geologic evidence for Archean plate tectonic processes within the framework of geophysical, geochemical and experimental observations. For the Late Archean (2.5–3.0 …
Volcanic and intrusive rocks with geochemical signatures typical of modern continental or oceanic arcs are uncommon in the Archaean and the archetypal Archaean granite …
The lithosphere of the Arabian–Nubian shield was mainly formed during an interval of about 150 million years near the end of the Proterozoic aeon. The events recorded in the rocks of …
