    • n glaciation The act of freezing.
    • n glaciation The result of freezing; ice.
    • n glaciation In geology, the present or former existence of a mass of ice, glacier, or ice-sheet, covering a certain region; subjection to the action of ice. Thus, it is said that the surface of the country in Sweden exhibits the effects of a former glaciation— that is, that the surfaces of the rocks in many places are smoothed or striated, as they are under or near actual glaciers in the Alps or elsewhere. Such surfaces are said to be glaciated.
    • n glaciation A consequence of or phenomenon caused by such a process or covering, as the striation and smoothing of rock-surfaces.

In science:

The nature of the glaciations in the Phanerozoic (0 − 545 Myr BP) are to a large extent well understood.
The Spiral Structure of the Milky Way, Cosmic Rays, and Ice Age Epochs on Earth
Comparison between the cosmic ray flux and the occurrence of glaciations shows a compelling correlation for the pattern speed chosen (fig. 10).
The Spiral Structure of the Milky Way, Cosmic Rays, and Ice Age Epochs on Earth
To check the consistency, a second analysis was performed to find the probability that a random distribution of glaciation epochs could generate a χ2 result which is as low as previously obtained.
The Spiral Structure of the Milky Way, Cosmic Rays, and Ice Age Epochs on Earth
To mimic the effect that nearby glaciations might appear as one epoch, we bunch together glaciations that are separated by less than 60 Myrs (which is roughly the smallest separation between observed glaciations epochs).
The Spiral Structure of the Milky Way, Cosmic Rays, and Ice Age Epochs on Earth
The fraction of random configurations that surpass the χ2 obtained for the best fit found before is of order 0.1%. (If glaciations are not bunched, the fraction is about 100 times smaller, while it is about 5 times larger if the criterion for bunching is a separation of 100 Myrs or less).
