VÝSLEDKY MIKROPALEONTOLOGICKÉHO STUDIA VRTŮ VYHLOUBENÝCH V RÁMCI VÝZKUMU SESUVŮ V MAGURSKÉM FLYŠI

Roč.13,(2006)

Abstrakt
Continuously cored boreholes drilled in framework of landslide research in the Outer Flysch Carpathians were studied micropaleontologically. Biostratigraphic results of boreholes near Nedašov indicate tectonic slice of the Bystrica Unit behind the nappe front of the Bílé Karpaty Unit not recognized by geological mapping. Agglutinated foraminifera zones in the Malá Bystřice 2 Borehole allowed evidence the repetition of Eocene strata in landslide accumulation due tectonic or landslide movements. In the Soláň Formation of the Solánec 1 Borehole pyritized radiolarians of Maastrichtian age indicate formation of oxygen-minimum zone above the bottom waters during deposition.
