The Escarpment owes its formation to three phases in different geological epochs.

The Palaeocene is the first geological epoch in the Neogene.

During the geological epochs the ocean originally prevailed everywhere.

The Oligocene is the last geological epoch in the Palaeogene.

Similar to the way sediment layers in planetary core samples show various geological epochs.

Dr. Oppenheimer has looked back at past geological epochs.

And then, really relaxed for the first time in what seemed like several geological epochs, I contemplated my immediate future.

Pieniny mountains formed at the bottom of the sea in several geological epochs.

Over geological epochs cracks expand to become caves and cave systems.
