A dune is a common geological landform composed of loose, unconsolidated material, typically sand, that is shaped by wind action. These features are created through eolian transport processes, where wind picks up sediment particles and deposits them when wind velocity decreases or when the material encounters an obstacle. The resulting structures vary widely in size, shape, and arrangement, and their formation and migration are governed by prevailing wind patterns and the composition of the parent sediment. The morphology and movement of dune fields provide valuable insights into paleoenvironmental conditions and the dynamics of sediment supply and removal within a landscape.
