Lithology and environment
| Primary lithology: | planar lamination sandy "siliciclastic" |
| Includes fossils? | Y |
| Lithology description: Dominated by parallel-laminated sandy sediments up to 35m thick. The upper contact to unit B2 is gradational. Mollusc shells are sparsely present and at least the upper part of the unit is marine. | |
| Environment: | shoreface |
| Glacial or sequence phase: | transgressive |
| Geology comments: Bennike (1990) interpreted the unit as representing back and foreshore and shoreface environment.The sediments were deposited during a transgression where sedimentation and sea level kept pace. | |
Taphonomy
| Modes of preservation: | body |
Collection methods and comments
| Reason for describing collection: | general faunal/floral analysis |
| Collection method comments: faunal list from observation of four localities (not listed) | |
