Revision as of 16:44, 17 December 2018 by 2dev>Jmdonev
A geologic eon is the largest unit of time for the geologic time scale (Figure 1). Geologic eons are also referred to as "eonothems" (the chronostratigraphic name) or simply "eons". Eons are hundreds, even thousands, of years in length. Eons are made up with shorter eras.[1]
Currently the eons are:[1]
- Phanerozoic (the current eon)
- Proterozoic (Precambrian)
- Archean (Precambrian)
