-
A.
Sturtian glaciation

-
C.
Huronian glaciation
The Huronian glaciation was one of Earth's earliest and longest ice ages, occurring over 2.4 billion years ago and likely linked to the Great Oxidation Event and major climatic shifts.
-
D.
Kaigas glaciation
The Kaigas glaciation was an early Neoproterozoic ice age event in Earth's history, preceding the more extensive Sturtian glaciation and representing one of the planet's significant pre-Cryogenian glacial episodes.
-
E.
Würm glaciation
