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." Mechanical analyses of sediments from Cretaceous and Eocene localities of the London basin, England, were used in the study.
