Description
Abstract. — The object of this paper is the study of the shaping and successive formations of the glacial margin in Artense : and of the extension of the ice sheets in that area where merged the confluent deposits of the Mont Dore, Cézallier and North Side of Cantal. In the areas of the glacial margin, many fluvio-glacial formations are to be noticed. Above Bort-les-Orgues, there existed a large lake whose location was closely determined by the structural pattern, and whose, presence is accounted for by a glacial barrier. If the reconstitution of the origin, of the shaping and deposits is comparatively easy, it is rather difficult to suggest a sequence of events to know precisely how many glacial periods led to these forms.
