Formation and composition of Earth’s Hadean protocrust

Nature, Published online: 02 April 2025; doi:10.1038/s41586-025-08719-3A modelling study shows that the trace-element composition of Earth’s Hadean protocrust is similar to that of the current average continental crust, severely compromising geochemical arguments for when and how plate tectonics began.
