The Padda Member corresponds in general to 6c of Kiær (1908) in the Malmøya area. Its name is derived from a small island northeast of Malmøya (NM992390) where the upper parts of the unit are well exposed, but its base is defined in a complete 30 m‑thick type section on the west coast of Malmøya (NM981377). Although shales also dominate this member, thin interbeds and lenses of both calcareous siltstone and limestone occur together with calcareous nodules. The base of the Padda Member is defined at the sharp introduction of these interbeds above the highly shaly upper parts of the underlying units. Characteristic faunal elements are both in situ and reworked populations of Stricklandia lens; other brachiopods, bryozoans, corals and stromatoporoids are also common.

The dominantly shaly Padda Member grades rapidly into the thinly interbedded limestones and shales (in approximately equal proportions) of the overlying Rytteråker Formation (Fig. 7b); the junction is taken at the first appearance of finely nodular limestone horizons assigned to the Rytteråker Formation. Bedding plane exposures show that many of these nodules are carbonate infills of endichnial burrows in the shales.
