Karlby klint

Theme: Danian strata and boundary to Selandian  

Locality: Karlby klint
Description of a Danish GeoSite


Primary identification


1. GeoSite no.:
GS - 2-4.

2. National locality no.:
NGI - 38.

3. GeoSite name:
Karlby Klint.

4. Location:
Denmark; Djursland, Eastern Jutland.

5. Co-ordinates UTM:
System ED50 Zone 32, x=616177, y=6261601.

6. Type of locality:
Coastal cliff.


Primary geological features


7. Main topic:
Bioherms.

8. Geo(morpho)logy:
Bedded greyish white bryozoan limestone with chalk matrix and occasional dark flints. Bedding is enhanced by the beds of flints and demonstrates quasicircular biohermal mounds that climb each other towards southeast.

9. Frame / context:
Sedimentology.

10. Chronostratigraphy:
Early Danian.

11. Primary value:
History of geology (a depositional interpretation of the bryozoan limestone is related to the locality.

12. Comparative evaluation:
The same stratigraphic interval and mounded depositional structure is demonstrated at the cliff of Stevns (GS - 2-1), which is part of the type area for the Danian period.

13. Comparable GeoSites:
In Denmark: Stevns Klint (GS - 2-1).
In Sweden: Limhamn Quarry.
