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


A type of  aeolian deposit.


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

     Drift deposits (Greeley et al. 2002)


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.
