Chromium isotope evidence in ejecta deposits for the nature of Paleoproterozoic impactors
International audience Non-mass dependent chromium isotopic signatures have been successfully used to determine the presence and identification of extra-terrestrial materials in terrestrial impact rocks. Paleoproterozoic spherule layers from Greenland (Graensesø) and Russia (Zaonega), as well as som...
