2 lut 2022 · Archean Eon (also spelled Archaean Eon) was the second eon of Earth's history and it lasted from about 4-2.5 billion years ago. Archean rocks reveal that at this time, volcanoes were rapidly erupting as a result of the excessive heat inside Earth's crust.
The intense heat that was a hallmark of the Hadean Eon (4.6 billion to 4 billion years ago) likely prevented most surface rock from solidifying. Conditions cooled somewhat during the Archean Eon (4 billion to 2.5 billion years ago), allowing rock to solidify.
