Waves and weathering at 3.7 Ga: Geological evidence for an equitable terrestrial climate under the faint early Sun
Chemical sedimentary rocks such as banded iron formation (BIF) and pillow basalts are persistent features of the oldest volcanic and sedimentary record by 3.8-3.7 Ga, and are direct evidence for oceans by the start of the Archean. However, their presence
