Description of primary interest:
The profile of flysch deposits outcropped along the Rzyczanka Stream Valley begins with gently folded Veřovice black shales with intercalations of thin-bedded laminated sandstones and local siderite concentrations. In some sandstones different taxons of trace fossils are well visible. Several stratigraphical species of dinocysts have been found. They establish the age of Veřovice Beds on Aptian and Lower Albian. Upstream the occurrence of medium and thin-bedded laminated quartzitic sandstones is noted. Veřovice Beds gradually passing upward into Middle Lgota Beds. They are developed as thin bedded quartzitic, dark, sandstones with distinct parallel and cross lamination. They are intercalated by dark quartzitic shales. Lgota Beds contain a relatively low diverse trace fossils assemblage and frequent and well-preserved dinocysts. A few small faults can be visible. The Lgota Beds represents Upper Albian and Cenomanian. Upstream the red and green variegated, non-calcareous shales are exposed. The shales contain single layers of radiolarites. They are covered with a complex of light, rhythmically bedded turbiditic limestones and marlstones intercalated by marly shales. The limestones and marlstones contain a differentiated assemblage of trace fossils. Rich dinocysts community supplemented by poorly preserved nannofossil and single shells of bivalves are noted. Variegated shales and carbonate flysch complex corresponds with Middle Turonian and Lower Coniacian. Up the stream the carbonate complex passes into medium and thick-bedded glauconitic sandstones of the Godula Beds.
