Subglacial Limestone Deposits in the Canadian Rocky Mountains

Abstract

FORD et al.1 have recently reported the discovery in the Rocky Mountains of Canada of calcite deposits which they have ascribed to a subglacial origin. The occurrence of such subglacial limestone deposits is, however, neither as rare in glaciated lands nor as neglected in the literature as they seem to believe. The problems of genesis noted by Ford et al. are therefore reviewed here in the context of a wider literature.
