Geology

Short characteristics of the site: The Bohemian Cretaceous Basin and Tertiary volcanics. The Vlhoš phonolite hill, 31 Ma old is dominating this area. The surrounding area consists mostly of quartzose sandstones of the Jizera Formation. Fining-upward cycles about 30 mn thick, are typical for them. Emplacement of a sodalitic phonolite wsas accompanied with ripping up blocks of Cretaceous and underlying rocks, including phyllites and mica schists. Northern margin of the Vlhoš Hill is cut by important fracture zone.
