Scientific paper

We report Sr-Nd isotope parameters for impactites from the 100 km sized Popigai impact crater, Siberia. One tagamite whole rock sample, and six impact melt glass samples, separated from breccias, show present-day epsilon-Sr between +351 and +395 and epsilon-Nd of about -23.5; the model ages (in Ga) are: Sr(UR) about 2.1, and Nd(DM) about 2.2. Three gneiss whole rocks, display much more variations in epsilon-Sr and epsilon-Nd, and slightly higher Nd(DM) model ages of 2.4 Ga. Glassy ejecta material in late Eocene deposits in the Western Hemisphere has distincly different isotope parameters, ruling Popigai out as source crater.
