The Hadean, Archean, and the protozoic eons.
The four eons of the geologic time scale are the Hadean, Archean, Proterozoic, and Phanerozoic eons. These eons span Earth's history from its formation to the present day, each characterized by distinct geological and biological events.
These three eons form the Pre-Cambrian supereon.
There are four eons dividing the geologic scale. Three occurred during the Precambrian era.
Supereon is the longest classification of time in geology. The Precambrian period is a supereon comprised of the Hadean, Archean, and Proterazoic eons.
The Precambrian era spans from about 4.6 billion years ago to 541 million years ago, encompassing almost 90% of Earth's history. It is divided into three eons: the Hadean, Archean, and Proterozoic eons.
Eons are divided into eras, which are further divided into periods. Each period is then subdivided into epochs.

Precambrian - It extends from 4.6 billion years ago to the beginning of the Cambrian Period (about 541 Ma). It includes three eons, the Hadean, Archean, and Proterozoic.
