History of Meteorites from the Moon Collected in Antarctica
In large asteroidal or cometary impacts on the moon, lunar surface material can be ejected with escape velocities. A few of these rocks were captured by Earth and were recently collected on the Antarctic ice. The records of noble gas isotopes and of cosmic ray—produced radionuclides in five of these...
