Krumbein sphericity
WebAbstract. Sphericity of quartz grains in sediments determined by three dimensional measurement varies from 0.5 to 1.0 around a mean of 0.75 sphericity units and is approximately normally distributed. Differences in sphericity of quartz grains between arkoses, graywackes, and quartzites are not large and arkoses are least spherical, … Web1932, 1933) defined “Sphericity” as the measure of the overall shape of a particle at the largest scale or “Form” suggested by Barrett ( 1980). Sphericity has been defined by …
