Stratigraphy
Formation: | Stappogiedde | Member: | Innerelv | ||
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: The Innerelv Member is in the same stratigraphic section as the basal portions of the the Lower Brevik Formation which is Vendian in age. The member is 275m thick and sonsists of two shallowing-upward sequences, each representing a transition from offshore marine (below wave-base) to wave-influenced, shallowing subtidal and intertidal deposition. |
Lithology and environment
Primary lithology: | wave ripples,"cross stratification" lithified sandstone |
Secondary lithology: | lithified mudstone |
Includes fossils? | Y |
Lithology description: General for the member: interbedded greenish-grey shales and fine-grained, ripple cross-laminated sandstoens (south westerly paleocurrent interpretted from asymmetrical ripple marks) with thick interbeds of medium to coarse, parallel laminated sandstones with rippled tops and deformation due to slumping and loading. Fossils found in a group of beds comprised of fine sandstones with ripple cross-laminations, climbing ripples, and thin mudstone interbeds. | |
