archaean
The Archaean, also spelled Archean, is a geologic eon that spanned from about 4 billion to 2.5 billion years ago, during which the Earth's crust had cooled enough to allow the formation of continents and life began to arise. It is often referred to as the age of the oldest known rocks, as it is denoted by the significant geological, biological, and atmospheric changes that occurred during this period. It is the second of four eons of the Earth's history, preceded by the Hadean and followed by the Proterozoic.
