Coarse sand sheet (Pye and Tsoar 1990); Sand levee
Description
Zibar are recognized by their coarse grain size, which is distinct in an aeolian system as the wind is generally capable of most easily carrying fine- to medium-grained sands. These coarse-grained, rounded bedforms have low amplitude and lack well-developed slip faces. The zibar are interbedded with interzibar deposits which also comprises relatively coarser sands with low-angle flat-ripple laminae (wind ripples). In the absence of the zibar, these coarse-grained sandy layers with low-angle flat-ripple (wind ripples) laminae combine to form amalgamated interzibar deposits (Biswas 2005; Neilson and Kocurek 1986).
