Meteoritic highly siderophile element and Re‐Os isotope signatures of Archean spherule layers from the CT3 drill core, Barberton Greenstone Belt, South Africa

Archean spherule layers represent the only currently known remnants of the early impact record on Earth. Based on the lunar cratering record, the small number of spherule layers identified so far contrasts to the high impact flux that can be expected for the Earth at that time. The recent discovery...
