Abstract

The clastic dykes in the Ernstbrunn Limestone (Tithonian to ?Hauterivian) of the quarry on the Mariánský kopec Hill in Mikulov (Pavlov Hills) are filled by limestone breccia with clayey-micritic matrix and clayey glauconitic silt to sandstone. These sediments represent a fill of the more or less opened cleft along the strike-slip and thrust faults. Poor and corroded nannofossils and foraminifers evidence the Middle to Upper Turonian. The lithology and microfossil content show close affinity to the Klement Formation, Ždánice-Subsilesian Unit transgressively overlying the Ernstbrunn Limestone. The sandy marls filling the fault-gap in the Ernstbrunn Limestone in the NW quarry-face contained Upper Jurassic foraminifer fauna of questionable autochthoneity.
