Evidence from ancient greenstone belts confirms that impact-derived meteoritic materials and spherules are preserved within early Archean sedimentary rock sequences.

The analysis

The retrieved papers include studies detailing ancient spherule layers and meteoritic components preserved in early Archean sedimentary sequences (such as the Barberton Greenstone Belt), supporting the claim that meteoritic evidence is found in very old sedimentary rocks.
