Road constructions of the R48 Highway enabled field observations of bedrock units hidden in the area between Rychaltice and Frýdek-Místek beneath extensive Quaternary cover. In the Subsilesian Unit following formations/members were documented: 1. Frýdek Fm. (Maastrichtian–Lower Eocene), 2. Frýdlant Fm. – variegated clays (Middle Eocene), 3. Menilite Fm. – Šitbořice Mb. (Upper Kiscellian). Two formations of the Silesian Unit were identified: 1. Hradiště Fm. (Barremian?), 2. Chlebovice Beds (Cenomanian). In the olistostrome enclosed in the Chlebovice Beds, small olistolith of Oxfordian limestone was proven biostratigraphically (foraminifers) among the frequent blocks of the Štramberk-type limestone.
