==Dunes==
Dunes are formed by wind deposition and transport, then the sediments accumulate in a variety of dune forms. Dune morphology is determined by the availability of sand, wind intensity, and the variability of wind directions (Lancaster, 1999; Pye and Tsoar, 1990). Dune consists of well sorted and well rounded grains, mostly quartz rich , but also heavy minerals and rock fragments are present. Coastal dune consists of many ooids , skeletal fragments, and other carbonate grains. Eolian dune is characterized by the presence of large cross bedding.
