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 … WebAbstract. On the contemporary Earth, distinct plate tectonic settings are characterized by differences in heat flow that are recorded in metamorphic rocks as differences in apparent thermal gradients. In this study we compile thermal gradients [defined as temperature/pressure ( T/P) at the metamorphic peak] and ages of metamorphism …
