Projectile remnants in central peaks of lunar impact craters

Unusual minerals observed in lunar craters were thought to originate from beneath the Moon’s surface. Numerical simulations show that rather than being vaporized, much of the impactor material can survive in the crater, implying that the unusual minerals come from the impactor and may not be indigenous to the Moon.
