List of geotopes in the Aschaffenburg district

This list contains 36 (as of August 2016) geotopes in the Lower Franconian district of Aschaffenburg 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.

Copper mine Wilhelmine E von Sommerkahl	more pictures	671G001	Summer bald position	Spessart	Spectacular wallpapers of brightly colored copper minerals, especially green malachite and blue azurite, cover the quarry walls of the Wilhelmine copper ore mine. The copper minerals are located in an orthogneiss that was formed around 335 million years ago during the Variscan orogeny. Hydrothermal veins lead as ores made of colored copper gravel (bornite), silver-containing arsenic (tennantite), copper pyrites and pyrite in addition to quartz and barite as veins. The geotope is one of Bavaria's hundred most beautiful geotopes and is explained on site with a corresponding information board.	5000 100 × 50	Type: Gallery Type: Gneiss	Quarry	especially valuable	Natural park	Bavaria's most beautiful geotopes No. 23
Copper slate quarry Help God NE von Großkahl		671G002	Kleinahl position	Spessart	Mining on copper slate has been documented here since 1454 and continued with interruptions until 1835. Copper, lead and silver were extracted. On the slope of the Habersberg, the circular pings of the former shaft and heaps are preserved as mining tools. Copper shale with traces of lead and copper minerals can be found on the heaps. The former mouth holes of the old Kahler tunnel and the Maximiliansstollen should still be able to be located on the basis of escaping mine water. The area is designated as a ground monument (Fig. 3, light red area, monument no. D-6-5821-0026). Unfortunately, part of the former mining site has been covered by an excavated earth dump.	0 not specified	Type: Halde, Pinge / nfeld Type: Mudstone , non-ferrous metal ore	Ping	precious	Soil monument, landscape protection area, nature park
Copper shale mining on Rothen Rain NE by Sailauf		671G003	Sailaufer Forst position	Vorpessart	The medieval duckel mining on copper slate left a large number of pings here. In the Duckel mining, a shaft was sunk into the copper shale and this was dismantled. The copper slate was then excavated from the side. Instead, a new shaft was sunk some distance away before support was needed. Copper and lead were extracted. The Schachtpingen are still up to 3 m deep, the heaps have a diameter of up to 30 m. The site is a ground monument (monument no. D-6-5921-0048).	357500 650 × 550	Type: Pinge / nfeld, shaft type: Bricks	Ping	precious	Soil monument, landscape protection area, nature park
Dune in Kühbruch E from Kahl a. M.	more pictures	671R001	Alzenau position	Lower Main Level	The sand dune in Kühbruch, together with the adjoining dune in the Sauweide, form the Neufeld sub-area belonging to the Alzenauer Sande nature reserve. On the narrow, irregularly shaped dunes, the flat windward slope to the west and the steeper leeward slope in the east can be easily understood. Strong westerly winds picked up fine sand from the gravel of the Main and Kahl during the cold times and deposited it elsewhere in the form of drifting sand covers and dunes.	6000 200 × 30	Type: Dune Type: Sand	no information	precious	Nature reserve, landscape protection area, FFH area

You can see a narrow, irregularly shaped stretch of dunes. Strong westerly winds picked up fine sand from the gravel of the Main and Kahl during the cold times and deposited it elsewhere in the form of drifting sand covers and dunes.	14400 180 × 80	Type: Dune Type: Sand	no information	significant	Nature reserve, landscape protection area, FFH area
Beutelstein SW from Oberbessenbach		671R003	Bessenbach position	Vorpessart	In the forest, blocks of wool-sack-weathered diorite are spread over the entire slope.

Quartz porphyry quarry NE from Sailauf		671A004	Sailauf position	Spessart	Rhyolite was mined in the Hartkoppe quarry north of Sailauf. It is a fine-grained, dense rock of reddish to reddish-gray color and has a fine-porphyry structure. The rhyolite body is cylindrical in the surrounding gneiss of the red gneiss complex and is covered by sediments of the Zechstein. Larger crevices, which can usually be traced almost vertically through the rock, were later filled with iron, manganese and arsenic minerals. The quarry is the type locality of the minerals Sailaufit and Okruschit. The dismantling stopped at the end of 2017. On the first level of the quarry there is an information board on which you can find out more about the quarry and its minerals and look into the quarry. This board is part of the approximately 10 km long Bleckmaul & Sailaufit cultural circuit, which begins in Sailauf at the St. Vitus Church.	60000 300 × 200	Type: rock type, minerals, type locality 4 contact type: rhyolite, dolomite stone, mudstone	Quarry	precious	Natural park
Aufgel. Quartzite quarries NNE from Geiselbach		671A034	Geiselbach position	Vorpessart	On the Kreuzberg north-northeast of Geiselbach there are several abandoned quarries. The rocks extracted here belong to the 4th quartz range of the Geiselbach Formation. Very few good outcrops of this rock still exist. On the basis of paleontological findings of pteridophytes (vascular pore plants) and spores, the quartzite and the rocks that emerge (partly garnet-bearing mica schist and quartzite-mica schist) can be placed in the Silurian-Devonian border area. There are several mostly very small (approx. Five by five meters) mining sites and a larger (approx. 40 by 50 meters) quarry. The building material for the Church of St. Magdalena in Geiselbach was dismantled in one of the quarries. The extensive mining area extends over an area of around 300 by 150 meters on the southern slope of the Kreuzberg. It is located in a high forest and is easily accessible via an unmarked hiking trail. Outcrops are only available in a few places, but sufficient heaps and readings are possible everywhere.	2000 50x40	Type: Rock Type: Quartzite	Quarry	precious	Landscape protection area, nature park
