An electron microscope examination of beach and glacial pebbles suggests that these two environments do not impress distinctively different textures on pebble surfaces. A detailed study of the surface textures of beach pebbles indicates that the size reduction is predominantly an abrasional rather than solutional process. The three textural features noted, flat planar surfaces, pits, and arc-shaped fractures, were characterized by an abundance of mechanical breakage blocks slightly modified by solution. All three textural types were experimentally duplicated.
