Geology
Short characteristics of the site:
Series of outcrops in a railway cut. Transgression of Cretaceous over Caboniferous is exposed. Carboniferous Kladno Formation consists mostly of arkoses, basal Cenomanian sediments of quartzose sandstones and subarkoses. Common weathering phenomena as honeycombs. This locality offers best example of the Cretaceous transgression over Carboniferous.
