N2 - The interpretation of glacigenic diamictons is a subjective process, for which
quantitative support is frequently sought from parameters such as clast shape and fabric. It has been widely suggested that different glacigenic diamicton facies possess distinct clast-fabric
signatures. This paper examines this concept using a data set of 111 clast fabrics, and a synthesis of published results. Eigenvalues are calculated and compared for a variety sedimentary facies. It is concluded that clast fabric alone is not able to discriminate between different glacigenic
facies, and it is argued that clast fabric offers little quantitative support in the interpretation of glacigenic sediments. It is suggested, therefore, that although clast fabric may continue to have
a role as an indicator of relative strain at specific sites, its use in the discrimination of glacigenic
facies is limited. Consequently, we should be much more selective in undertaking such analyses in the future.
