Heiligenhafener rock (also "Heiligenhafener Kieselgestein") is a debris that occurs locally in Schleswig-Holstein , especially in the southern parts of the country . Its name goes back to an occurrence of clods in a cliff ("Hohes Ufer") near Heiligenhafen in the Hohwachter Bay . A similar occurrence near Kühlungsborn (Mecklenburg-Western Pomerania) is called "Scherbelstein" there.
The gray-green, sometimes yellowish marl and clay stones have a clearly recognizable fine layering. These are deposits of shallow marine waters from the middle Eocene ( Lutetian ). There is, however, a glacial scaling in which the Obereocene has also been proven. The rock is sometimes rich in sponge needles , foraminifera and coccoliths . Larger fossils are rare.
Due to its higher fine sand content, the Heiligenhafen rock differs from the Lower Ozone Londonton (Tarras) that also emerges on the Heiligenhafener Kliff and on the nearby island of Fehmarn ( Katharinenhof ). In the middle of the Heiligenhafener Kliff, Heiligenhafener Rock and Londonton appear side by side. The Heiligenhafen rock is extremely brittle there - in contrast to the sometimes very large and solid debris in other places. Londonton, on the other hand, appears as a tough, plastic mass.
