Ristinge Klint

Theme: Glacially dislocated coastal cliffs 

Locality: Ristinge Klint
Description of a supplementary Danish GeoSite


Primary identification


1. GeoSite no.:
GS - 4-3.

2. National locality no.:
NGI - 129.

3. GeoSite name:
Ristinge Klint.

4. Location:
Denmark; The Funen archipelago (Southern Langeland)

5. Co-ordinates UTM:
System ED50 Zone 32, x=603351, y=6076896.

6. Type of locality:
Coastal cliff exposure.


Primary geological features


7. Main topic:
Glacial stratigraphy and thrusting.

8. Geo(morpho)logy:
Repeated successions over 2 km of sea cliff in 34 tilted Late Weichselian thrust blocks with interbedded tills, meltwater deposits and lacustrine beds. The lake deposits are of a glossy clay variety (Det Blanke Ler) dating from the Eemian interglacial. They are overlain by the shallow marine Cyprina clay which was deposited i a relatively warm climate. Weichselian depositional incidents of till deposition are recorded from the Elder Baltic Glacier and the North West Glacier, which are seperated by meltwater- and eolian deposits. This succession was thrusted and overstepped by the Younger Baltic Glecher, which left local Weichselian tills, whereafter the Ice Push Event of the Belts left a drape of meltwater sand and gravel as the final glacial bed.

9. Frame / context:
Structural geology.

10. Chronostratigraphy:
Saale, Eem and Weichsel.

11. Primary value:
Glaciottectonic thrusting of flakes.

12. Comparative evaluation:
Informal typelocality for Weichsel stratigraphy in the Baltic Sea area, in which all Weichselian glacial pushes younger than the Eemian are documented.

13. Comparable GeoSites:
In Denmark: In Sønderby Klint, Southwestern Funen, a comparable glaciotectonically deformed section is visible. This exposure is, however, less impressive and the local Eemian deposits (bogs) are no longer exposed.
