Distinction between dune, beach, and river sands from ...

Since dune and river sands are skewed in the same direction, a further criterion is needed for distinguishing river from dune sands which have overlapping sorting characteristics. This has been found by separating the light mineral grains from those of the heavy minerals and determining the mean grain-size ratio of quartz and that of a specific ...
