Abstract
Natural rock data and thermo-mechanical model predictions seem to indicate a tectonic transition in planet earth from "pre-subduction" vertical tectonics to "modern subduction" regime of horizontal plate motions between 3.2 and 2.8 Ga. Mesoarchaean metamorphic rocks are, therefore, ideally suited to decipher the early earth tectonic transition. Despite their importance, Mesoarchaean metamorphic history is rather meagre in the rock record due to overprints of younger tectonothermal events that mostly obliterate their early history.
