Elbe Sandstone
Elbe Sandstone ((ドイツ語:Elbsandstein)) describes sandstones that naturally occur in North Bohemia and those parts of Saxony within the area around Dresden. It is named after the River Elbe, which cuts through the sandstone region in a transverse valley, the ''Elbe Valley Zone''. It reaches the surface most strikingly in the Elbe Sandstone Mountains, which are divided into the regions of Saxon Switzerland on German soil and Bohemian Switzerland on Czech territory. The term Elbe Sandstone is used in both geological and economic contexts.
== Geological term ==
In a geological sense, Elbe Sandstone includes all sandstone types that occur in the region of the Elbe Valley and were formed during the Cretaceous period. It consists mainly of quartz grains that are cemented by silica. The ratios and constituents of its accessory minerals are variable. Its deposits border on the area of the Lusatian Massif (Lusatian anticlinal zone), the Meißner Massif, the gneiss of the Eastern Ore Mountains, the Elbe Valley Slate Mountains and the territory of the Czech Republic by the northeastern foothills of the Central Bohemian Uplands and the fringe of the Eger Graben.
