Abstract

Fifty-nine sand samples have been analyzed to determine the relationship between depositional environment and quartz grain roundness. Roundness as used in this study is based on the sharpness of the corners and edges of individual sand grains from three size fractions. The environments from which samples were taken are: off shore, dune, beach ridge, open swash zone, protected swash zone, marsh, lagoon, and river. Sands from certain groups of environments show distinctive roundness patterns.
