Onset of plate tectonics by the Eoarchean
One of the most contentious areas of Earth Science today is when, or whether or not modern-
style plate tectonics was in operation in the Archean Eon. In this review we present evidence …

The diversity and evolution of late-Archean granitoids: Evidence for the onset of “modern-style” plate tectonics between 3.0 and 2.5 Ga
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 …

Sedimentary rocks and crustal evolution: tectonic setting and secular trends
SM McLennan, SR Taylor - The Journal of geology, 1991 - journals.uchicago.edu
A significant change in the composition of turbidites deposited at active tectonic settings is
seen at the Archean/post-Archean transition. In comparison to post-Archean active margin …

Genesis of high Mg# andesites and the continental crust
PB Kelemen - Contributions to Mineralogy and Petrology, 1995 - Springer
The continental crust has an andesitic composition with high Mg/(Mg+ Fe) and Ni contents
which may be too high to have formed by differentiation of basaltic magmas. Instead, mantle …
