Dachstein Limestone from Krn in Julian Alps (Slovenia)

The Dachstein limestone from Krn is characterized by Lofer development. The section encompasses 30 cyclothems on average 3-4 metres thick. Intra- and supratidal environment of deposition is evident by stromatolites, loferite and tempestite breccias. They were all locally affected by early diagenetic dolomitization. Biomicritic limestone with several horizons of megalodont clams was deposited in shallow and restricted shelf. Basal members A of the Lofer cyclothem are developed only exceptionally. Solution cavities are fairly common, being infilled by sparry calcite and insoluble rich red limestone. The limestone was deposited on the Julian carbonate platform near its passage part to the southerly lying Slovenian basin. In this part reigned specific circumstances that resulted into formation of very numerous corrosion vugs; they are filled in their central parts by variegated marly clay. Interesting are frequent tempestite layers. Their origin is explained by synsedimentary tectonic processes that caused fracturing and slumping in unconsolidated limestone beds.
