Abstract
Pebbles from a Pothole: A Study in Shape and Roundness
Dorothy Carroll
ABSTRACT
An assemblage of pebbles collected from a pothole in even-grained sandstone is described. Variation in shape and roundness for the different lithologic types of pebbles is given. The influence of original shape of the piece of rock worn into a pebble is stressed, and a series of stages in abrasion is described. The observations are compared with the facts and principles obtained by experiments on pebble abrasion by workers elsewhere, and it is believed that the experimental principles are exemplified by this sample of pebbles abraded in a pothole.
