Thin, half-molten first crust: model kan níbi tí impacts, kì í ṣe internal heat, ran Hadean
Earth first eon, Hadean, left almost no rock record. Modelling study yìí asks what crust would look like once impacts are included. Using stochastic declining impact-flux model and benchmarked crust/mantle heat-flow simulations, authors find impact heat could exceed Earth internal heat by at least order of magnitude for most Hadean, leaving thin crust (<~5 km) partially molten just few kilometres down — too weak, they argue, for plate tectonics, prone to recycling into mantle, explaining missing Hadean material. As impacts waned after ~3.9 Ga, lasting continental crust could form around when oldest felsic rocks appear — ‘likely not a coincidence.’ Conservative lower-bound heating makes qualitative result robust though exact numbers not fixed. Strong coherent model, not direct observation.
