Stratigraphy of Julian and Tuvalian Substage in the Oslica at Muljava Area (Slovenia)

Abstract

The Julian and Tuvalian lithologic column in the Oslica area starts with dolomitic breccias with limonitic groundmass and with a bauxite giving evidence of areal expose on the boundary between Cordevolian and Julian. Afterwards, precepitation of carbonate rocks followed. In the lithological interval where the limestone breccias predominate, oncolitic horizons are most characteristic. The Carnian sedimentary succession in the Oslica is terminated by a dolomite with intercalations of marls, bedded micritic limestones and a dark grey dolomite with a roundish disintegration. The lithological composition and sedimentological characteristics of the succession indicate an origin in the littoral environment.
