Stoss-side mud-drapes: deposits of interdune pond margins

Arcuate mud-drapes have been observed in an interdune area in southern Tunisia. They are believed to have been formed by deposition from ponded water around aeolian dunes during flood events. They are preferentially preserved on the stoss-side of the dunes as a result of subsequent dune migration, and exhibit extensive evidence of animal tracks. They are useful in illustrating dune-interdune dynamics and recording the type of animals present.
