The Archean rock record contains seventeen asteroid impact ejecta units that represent the terrestrial vestiges of an extended late heavy bombardment (LHB). Correlated impact ejecta units include 3472–3470 Ma impact spherule layers in the Barberton Greenstone Belt, Kaapvaal Craton, South Africa, and the Pilbara Craton, Western Australia, and several ejecta units dated between 3250 and 3220 Ma and between 2630 and 2480 Ma (Lowe and Byerly, 2010; Lowe et al., 2003, 2014). This paper reports the...[Show more]
