Résumé

In this note the writer points out the existence, in the Mesozoic of the Lebendun nappe, of a stratigraphic member which - in the nature of its parent sediments, in its stratigraphic position and in its mineralogical and petrographical characters - is directly analogous to the Quartenschiefer of the south slope of the Gottard massif. Consequently the author suggests the existence, during the upper Triassic, of an analogous paleogeographic environment either in the penninic Lebendun zone or in the ultrahelvetic one, outcropping along the southern border of the Gottard massif.
