Geology & Origin

The Studenec Quarry near Jilemnice is one of the best known volcanic mineral localities in northern Bohemia. The basaltic rocks contain numerous gas cavities that formed during the cooling of lava. These cavities were later lined and filled by mineral rich solutions, producing a variety of secondary minerals. Analcime is one of the characteristic zeolite minerals of such deposits and commonly forms pale crystal aggregates. Celadonite is a potassium rich phyllosilicate formed through hydrothermal and post volcanic alteration processes and is responsible for the characteristic green coloration of many specimens from Studenec.
