The limestone is very fine grained (calcilutite) and is slightly lithified. There is a local occurrence of bryozoa chalk. As in the other outcrops of Danian limestone in GPWJ there are many regular layers of flint. Fossils, both macrofossils investigated by Ødum and newer studies of nannofossils, indicate that the deposit is of Middle to Upper Danian age. The limestone is quite poor in fossils which may be due to it being deposited in relatively deep water. The assemblage does, however, include fossils and fragments of calcareous sponges, corals, crinoids, starfish, sea urchins, brachiopods and mussels (spongiae, anthozoa, crinoidae, asteroidea, echinoidea, brachiopoda, lamellibranchiata).
The elevated limestone forms a dome-shaped landscape which, together with the low-lying limestone at the coast (site 42 – Odby Klint), clearly demonstrates the effect of a rising salt structure. Despite the erosive effect of several glacial advances the central part of the salt structure is almost 30 m higher than the exposed Danian limestone at Odby Klint, outside the area influenced directly by the salt dome.
