Fifty-nine sand samples have been analyzed for roundness to determine the relationship between depositional environments grain roundness. The roundness study was patterned after an investigation by Heal and Shepard (1956). Roundness as used in this based on the sharpness of the corners and edges of individual grains from three size fractions. The environments were taken are: off shore, dune, beach ridge, open swash zone, protected swash zone. marsh. lagoon and river. From each of these enviromentss five samples were selected for mechanical analysis. The sorting and grain size parameters used in this analysis show no significant difference in depositional environments. Sands from certain groups of environments show distinctive roundness patterns.
