Upper Triassic dolomite – Gornje Vrapče

Outcrops near the shooting gallery in Gornje Vrapče represent a typical ‘ Hauptdolomit’ sequence consisting of frequent alternations of dolomicrite, fenestral dolopelmicrite, and, somewhat less commonly, dolostro¬ ; matolites. The latter two lithological types occur most frequently as intercalations, lenses, and larger or smaller fragments in a dolomicritic matrix. The dasyclad alga Dissocladella bystrickyi was described from this locality (SOKAČ & GRGASOVIĆ, 1995), in a grey, light grey and dark grey skeletal– intraclastic dolomite, which originated by early-diagenetic dolomitization from an original wackestone calcareous sediment.
