Abstract

Samples of the well known drift at Morpha-bychan, Wales, have been examined with a Scanning Electron Microscope. Examination of the quartz grain surface textures indicates that the deposits cannot be regarded as solely the products of periglacial slope activity. Grains in the Blue Head have surface texture attributable to glacial abrasion
