Mesozoic stratigraphy of Eastern Svalbard: a discussion

Abstract

This paper proposes an alternative to the complex stratigraphical nomenclature introduced in recent descriptions of the stratigraphy of Eastern Svalbard. We believe that the platform nature of the Mesozoic succession in Svalbard enables recognition of individual stratigraphical units over very wide areas. Our principal conclusions are that the Wilhelmoya Formation can be recognized as the upper formation of the Kapp Toscana Group and occurs throughout Eastern Svalbard. It overlies the De Geerdalen Formation on Hopen and Wilhelmoya. The Janusfjellet and Helvetiafjellet Formations can be recognized on Kong Karls Land.

“…Sample localities are indicated. Nathorst (1901), Worsley & Heintz (1977), Edwards et al (1979), Pickton et al (1979), Lauritzen & Ohta (1984), Worsley (1986), Doyle & Kelly (1988) and Larssen (1992). The oldest sediments on the islands belong to the Wilhelmoya (Svensk@ya) Formation and have been dated as Upper Triassic to Lower Jurassic (Rhaetian to Hettangian-Sinemurian).…”
