Geology

Short characteristics of the site: Meander of the Olše River exposes middle Paleocene marls of the Frýdek Formation of the Subsilesian Unit, with redeposited uppermost Maastrichtian paraconglomerates (slumps), submarine landslides and turbidite sandstones. The paraconglomerates contain rich association of exotic blocks: Devonian, Lower Carboniferous and Paleocene limestones with unical macrofauna, siltstones, arcoses and coal from productive Carboniferous, and crystalline rocks.
Regional geologic unit: Carpathian - Flysch belt - Outer (Menilit-Krosněny) group of nappes
Stratigraphy: mezozoikum - křída - svrchní křída - maastricht, kenozoikum - paleogén - paleocén
Subject: stratigraphy, sedimentology, paleontology, history

Genesis: sedimentary
Rock: claystone, limestone, sandstone, mica schist, aplite, volcanic rock (undifferentiated), phyllite, siltstone, arkose, black coal

Territorial conservation

Level of protection: Registered geological localities suggested for protection
Protection of a geol. phenomenon: B - Geological phenomenon is the reason for a recommendation to the protection
Conflicts of interests: ground instability, road construction
