It is a southeastern branch of the Lower Harz Mountains and extends between Blankenheim in the north, Wolferode near Eisleben in the east, Hornburg in the southeast and Beyernaumburg near Sangerhausen in the west.
In terms of natural areas , according to the handbook of the natural spatial structure of Germany, it is still assigned to the natural area Querfurter Platte and Untere Unstrutplatten of the Thuringian Basin (with edge plates) , directly in the border area to the eastern Harz foreland and the eastern Harz roofing .
The Hornburger Sattel is part of the eponymous plaice of the eastern Harz border, which runs from northwest to southeast. It separates the Sangerhausener Mulde along the Blankenheimer fault in the southwest from Mansfelder Mulde in the northeast. The main types of rock that occur are those of the basement ( Rotliegend ), as well as Zechstein and Buntsandstein . This contains small amounts of uranium with a total uranium reserve of around 400 tons, a small part of which is close to the surface in the sandstone. Extraction by leaching the sandstone by the Wismut company was considered, but this was not considered economical due to the small quantities.
