The study proposes a new roundness scale for sedimentary particles. The scale is defined by six roundness classes and is applied by comparing photographs of two sets of clay models—one with high sphericity and one with low—to classify particle roundness.
ABSTRACT A new roundness scale is proposed. This scale is defined by six roundness classes. Two sets of clay models were prepared to characterize each roundness class. One set shows a high sphericity, the other a low sphericity. Photographs of these models are used to determine the roundness of a particle by comparison.
