The Statherian Period (

Mya to 1600 Mya (million years ago). Instead of being based on stratigraphy, these dates are defined chronometrically.[2][3]

The period was characterized on most continents by either new platforms or final cratonization of fold belts. Oxygen levels were 10% to 20% of current values.[4]

By the beginning of the Statherian, the supercontinent Columbia had assembled.[7]

Approximately 1.7 billion years ago, natural nuclear fission reactors were generating power in what is now Oklo, Gabon.[8]
