Abstract
WITH the growing interest in ancient climates many geologists have questioned the validity, as indicators of glacial conditions, of those poorly sorted conglomerates which were called ‘tillites’ by earlier geologists. It is now recognized that very similar deposits can be formed by submarine slumping. Most geologists agree, however, that the presence of a striated surface beneath such poorly sorted conglomerates is strong evidence of a glacial origin1. To this criterion I would add the need to find several widely separated pavements of the same age.
