Mesoarchaean
The Mesoarchaean is a geologic eon spanning from 3,200 to 2,800 million years ago (Ma). It is the second of the four defined eons of Earth's history, following the Paleoarchaean and preceding the Neoarchaean. This period falls within the larger Archean Supereon. The Mesoarchaean represents a significant chapter in Earth's early development, characterized by ongoing continental formation and the emergence of early life forms.
During the Mesoarchaean, the Earth's crust continued to differentiate, leading to the formation of larger and
Evidence from this eon points to the presence of early life, primarily prokaryotic microorganisms. Stromatolites, layered
