Some Problems of Size and Sorting in Sands

Published online by Cambridge University Press:  01 May 2009

Abstract

For certain unconsolidated sediments there is a linear relationship between the arithmetic mean size and the “grading factor”, and sediments with an average particle size of 0·2 mm. show the maximum degree of sorting. An hypothesis has been developed to explain this relationship in terms of the environment of deposition.
