New paper, volatile-element isotopes in Oued Chebeika 002
New research published in Geochemical Perspectives Letters where Daman and colleagues measured potassium, rubidium, germanium, and copper isotopes in the meteorite Oued Chebeika 002, comparing them with CI chondrites and the asteroids Ryugu and Bennu to trace how volatile elements were distributed among the Solar System’s most primitive material.
