Geology
Short characteristics of the site:
A pit extracting Carboniferous refractory clays with a section of the Kladno Formation (Westphalian C+D). The overlying Cretaceous sediments of the Peruc-Korycany Formation and the Bílá hora Formation reveal spatial relationships among sedimentary units of the continental-to-marine transition. The Pecínov Member was defined at this site by Uličný and Špičáková (1996).Bohemian Permocarboniferousand Cretaceous. Active quarry exposing two important stratigraphical boundary beds: l) Between Cretaceous Cenomanian and Turonian, 2) between Permocarboniferous Nýřany and Radnice beds. Cretaceous boundary beds documents a boundary between terrestric and marine sedimentation.
