Sand formations that are caused by the action of the wind.

Notes
1. "Savary Island is capped with a thick sequence of aeolian sand that rests unconformably on sediments deposited during the last glaciation.

Where undisturbed by human activity the aeolian sediments form large stabilized parabolic dunes that trend to the northwest.

An investigation has revealed the presence of several buried soils, the oldest discovered so far dating to nearly 10,000 years. These sediments therefore represent a record of relative landscape stability (soil formation) and instability (aggrading sand) spanning nearly all of the Holocene."

2. In the study of geology and weather, the term Aeolian processes deals with the wind's ability to shape the surface of the Earth. It derives from the name Aeolus, the Greek god of the winds.
