Impact‐Generated Mixing, Melting and Vaporization of the Early Earth's Crust

open access: yesEarth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Earth's primary accretion was followed by a protracted flux of interplanetary collisions by leftover planetesimals. The effects of the largest collisions—with bodies possibly exceeding 1,000 km diameter—would have been devastating for terrestrial near‐surface environments.
