List of geotopes in the Haßberge district

This list contains the geotopes of the Lower Franconian district of Haßberge in Bavaria . The list contains the official names and numbers of the Bavarian State Office for the Environment (LfU) as well as their geographical location. This list may not be complete. Around 3,400 geotopes (as of March 2020) are recorded in the Bavarian geotope register. The LfU does not consider some geotopes suitable for publication on the Internet. For example, some objects are not safely accessible or may only be entered to a limited extent for other reasons.

Schlot breccia SE from Schweinshaupten		674A028	Bundorf position	Hassberge region	To the south-east of the Schweinshaupten bathing pond, a tertiary breccia slot is opened on a path embankment, which is part of the Heldburg gang. The total size of the chimney is around 100 by 75 m. Only about 10 percent of the chimney filling consists of basalt, xenolites from the deeper crust and crystalline are involved to a small extent. Mesozoic sediments form the main mass of the ejecta material: mainly claystones, marl and gypsum marl, as well as subordinate sandstones of the Coburg sandstone, the castle sandstone and the reed sandstone. This confirms the important finding that layers of the Jura were still present in the Haßberg Mountains in the Tertiary.	75 15 × 5	Type: Igneous structure Type: Basalt, Breccia	other information	precious	Landscape protection area, nature park
Geusfeld - ravine at the Marienkapelle		674A029	Rauhenebrach position	Sandstone Keuper Region	At the small Marienkapelle in Geusfeld there are sandstones of the Stuttgart formation (reed sandstone) in the embankment. In addition to thicker benches, in which the weathering has very nicely prepared the sloping structure, there are also benches a few cm thick with no recognizable internal structure. Towards the top, dark gray Latvians join in between the sandstone banks. The name reed sandstone comes from the stone breakers who mistook common horsetail remnants for petrified reeds. These sandstones were formed by a north-east-south-west running river system, which in some cases had sunk several tens of meters into the underground of the grave field formation (layers of estheria) before these river channels were filled with sand. The sandstones exposed here, with their thick, sloping benches, show the characteristic image of such a channel filling.	240 80 × 3	Type: sequence of layers, rock type: sandstone, claystone	embankment	significant	Natural park
Sandstone quarry between Koppenwind and Untersteinbach		674A030	Rauhenebrach position	Sandstone Keuper Region	The former quarry in Coburg Sandstone (Haßberge Formation) is largely overgrown and the walls are only partially accessible. Especially in the east wall, the thick sandstone is still well developed today. Sandy-clayey sediments follow above the work stone bench, some of which are deepened into the sandstone like channels. In a similar position, TRUSHEIM first found fossils of the leaf pod Triops cancriformis in 1934. These animals, which are only a few cm tall, belong to the longest-lived known animal species on earth. In the meantime proven since the time of the Upper Buntsandstein, it still occurs today, i. H. it has existed for at least 250 million years. Although the fossil layer is no longer there today, the global reputation (quote from GEYER 2002) of this information lies not only in the first discovery of the Triops, but also in the good quality of preservation of countless specimens in many stages of development from egg to adult.	4900 70 × 70	Type: Type locality, Animal fossils, Trace fossils, Vegetable fossils, Layer sequence Type: Sandstone	Quarry	especially valuable	Landscape protection area, nature park
