Aeolian, sometimes spelled eolian or œolian, are deposits of windblown sediments. Since wind has a much lower carrying capacity than water, aeolian deposits typically consist of clast sizes from fine dust to sand [ 52 ]. Fine silt and clay can cross very long distances, even entire oceans suspended in the air.Question: Arrange all the clastic rocks in the order of increasing grain size. here are the rocks: • Breccia • Coal • Conglomerate • Coquina • Chalk • Mudstone • Oolitic limestone • Sandstone • Shale • Travertine.

If there is a mix of grain sizes then it is ‘poorly-sorted’, and if all of the grains are uniform in size it is ‘well-sorted’. After …In order to be present in a sandstone as a lithic fragment, the grain size of the minerals in the lithic fragment must be smaller than the grain size of the sediment. Thus, granitic fragments will be expected to be rare, except in coarse sands, and volcanic and fine-grained metamorphic fragments will be expected to be more common.
