Talk:Aeolian sandstone

Large-scale cross beds and well-rounded sand grains are no longer considered as diagnostic features of eolian sandstone. In fact, there is a large volume of literature in sedimentology that has resulted from the controversy over eolian vs shallow marine origin of these rocks. Since early 1980s we know eolian sandstone are characterised by following small scale sedimentary structures: a. Reverse graded wind ripple srata, b. Adhesion structures, and c. A particular arrangement of grainflow, grainfall and wind ripple strata within eolian cross beds. Rounding of grains in a well sorted qurtz sand, though not diagnostic, are still considered to be to be suggestive of eolian origin of a sandstone.
