Definition

Windblown and deposited granular material with particle sizes of 0.0625–2 mm.

This entry discusses sand deposits in general; details on bedforms and other aeolian deposits can be found in the appropriate entries.

Subtypes by Deposit Hierarchy

Sand systems are self-organized into a hierarchy of superimposed sand patterns (bedforms) (Lancaster 1995). These forms are in a state of quasi equilibrium state; they cannot grow into a form belonging to another hierarchical order (Sharp 1963).

Scales of aeolian sand bedforms:
  1. (1)

     Ripples (from smaller aerodynamic and larger impact ripples to megaripples): They are controlled by reptation flux (Anderson 1987).

     
  2. (2)

    (Simple/elementary/basic)  dunes. Their formation is controlled by long-term wind trends.

     
  3. (3)

     Mega-dunes(giant,...
