Geology

Short characteristics of the site: Svratka Crystalline, Nature Monument in the Protected Landscape Area. Rocky feature erosionally separated from the main ridge of the Devět Skal formed of migmatized and biotite gneisses. Frost weathering acted as a main agent of rock separation. The rock consists mostly of its light part - leucosome - with quartz, plagioclase and potassium feldspar. Structure is granoblastic without preferred orientation.
