Barite-bearing stromatolites at the Permian- Triassic boundary in Gorski kotar (Croatia, Yugoslavia)

Barite-bearing dolomites in Gorski Kotar are conformably situated above the Upper Paleozoic clastic sediments, rich in early diagenetic pyrite. Discovery of cryptalgal fabrics in clastics and dolomites, together with other sedimentary features supports their affiliation to a tidal flat facies. The geological development at the locality Mrzle Vodice shows some elements of Sabkha environment.
