Geology

Short characteristics of the site: The relics of pilow lavas of the Zelezný Brod volcanic complex are preserved. The ductile defomoation (asymetric shape of piloow) allow to interpret the shering with top to the WNW sense. The more deformed part of outcoprs pass into the massive or bandes greenschist.
