Osterzgebirge
To the east it is adjoined by the Elbe Sandstone Mountains and, to the west, by the Elster Mountains and other Saxon parts of the Vogtland. South(east) of the Central and Eastern Ore Mountains lies the North Bohemian Basin and, immediately east of that, the Bohemian Central Uplands which are separated from the Eastern Ore Mountains by narrow fingers of the aforementioned basin. South(east) of the Western Ore Mountains lie the Sokolov Basin, the Eger Graben and the Doupov Mountains. To the north the boundary is less sharply defined because the Ore Mountains, a typical example of a fault-block, descend very gradually.
