Earth:Bratschen
From HandWiki
Bratschen are weathering products that occur as a result of frost and aeolian corrasion almost exclusively on the calc-schists of the Upper Slate Mantle (Obere Schieferhülle) in the High Tauern mountains of Austria. The term is German but is used untranslated in English sources.[1]
The calc-schist, which appears blue-gray when freshly broken, weathers to a yellow to brown colour and flakes off on the surface to form bratschen.[2]
These form steep (up to 40°), rocky, almost unvegetated mountainsides with an odd and rough-textured surface, caused by wind erosion. Bratschen are found on the mountains such as the Fuscherkarkopf, the Großer Bärenkopf, the Kitzsteinhorn, the Schwerteck, or on the eponymous Bratschenköpfen.
