Paleocene – Oligocene microfossil and palynological biostratigraphy of the wells DGU 38.1203 and DGU 38.1204, island of Fur, Denmark

Microfossil and palynological biostratigraphy was carried out on samples from 2 wells, DGU 38.1203 and DGU 38.1204, both located on Fur, in order to ascertain which lithological units they should be assigned to.

In well DGU 38.1203, samples 14–15 m to 40–41 m are assigned to the Viborg Formation. The Lillebælt Clay Formation (Beds L4–lower L5) is represented by samples 42–43 m & 48–49 m. The Knudshoved Member of the Røsnæs Clay Formation is present from 50–51 to 53–54 m. Sample 55–56 m is assigned to the Fur Formation based on microfossils and the Knudshoved Member of the Røsnæs Clay Formation based on palynomorphs. The Fur Formation is represented by samples 57–58 m to 59–60 m.

In well DGU 38.1204 all samples are assigned to the Fur Formation, apart from the lowest two samples, 44–45 m and 47–48 m, which represent the Stolle Klint clay.
