Sedimentary rhythms in the Jurassic and Cretaceous of Svalbard

Abstract The Janusfjellet Subgroup on Svalbard consists on a 400 to 500 m thick sequence representing shallow marine depositional environments. Coarsening-upward units, often separated by carbonate beds, are commonly found in rhythmic developments. Rhythmicities (285000(?) and 850000(?) years) in th...
