•Transgressive due to the transgressive sandstone bed, which also indicates rapid establishment of conditions favourable for bentic colonization.

•The repeated occurrences of siltstone and sandstone beds with hummockly lamination indicates a storm influence on a shelf above storm wave base.

•Lower part of the Deltadalen member: sandstone and siltstone interbeds are abundant.

•Calcite concretions are the most abundant in the upper part of the Lusitaniadalen Member but do also occur in the Deltadalen member, but with different carbonate mineralogy.

•The basal sandstone of the Deltadalen member consits of 2-3 meter of medium to fine grained glauconitic grey-green sandstone, that occasionally shows faint cross bedding.

•The sandstone is moderately bioturbated and has a patchly chert cement

•Above the basal sandstone, the Deltadalen Member consits of silty shale with intervals dominated by siltstone or very fine grained sandstone beds.

•Several intervals enriched in sandy siltstone beds occur throughout the member, and several show hummockly lamination, the upper part parts of which are often rippled. Bioturbation is sparse.

•The top of the member consits of thin sandstone beds forming an upward-coarsing upward sequence.
