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.
