Web30 de jan. de 2024 · Abstract. The ca. 3.8–3.6-b.y.-old Isua supracrustal belt of SW Greenland is Earth’s only site older than 3.2 Ga that is exclusively interpreted via plate-tectonic theory. The belt is divided into ca. 3.8 Ga and ca. 3.7 Ga halves, and these are interpreted as plate fragments that collided by ca. 3.6 Ga. WebThe time of the onset of plate interactions on Earth is unknown. Have plate tectonics-like processes been a general feature of Earth since its earliest history? It is important to know this at least when considering planetary heat-loss, element recycling and habitats for the origin of life. We report direct evidence for plate boundary processes before 3.7 Ga from …
