Kamenolomom Mariánská Skála
Active quarry in an irregular phonolite laccolith which penetrated into different levels of the Cretaceous sediments along a pre-existing tectonic structure in the Upper Oligocene (26 Ma). Later it was tectonically modified and intersected by the Labe River to form Mariánská hora Hill and Kamenný vrch Hill. The laccolith is formed by miaskitic natrolite sodalite phonolite passing into analcime sodalite phonolite in marginal parts of the body.
Located east of Ústí nad Labem.
