| Summary: | <div>The Upper Permian sediments from central part of the Dinarides contain three main facies : 1. - carbonates; 2.- evaporites with early diagenetical</div><div>dolomites and 3.- clastic rocks (siltstones and sandstones) and one special rock type- carbonate cavity breccias. The carbonate facies include lagoonal and intertidallimestone, evaporite facies contain gypsum (originated by hydration of anhydrites), early-diagenetical dolomites and anhydrites deposited in coastal sabkha environment.</div><div>The clastic rocks were deposited either fore-shore or playa to saltlake</div><div>playa environments. The carbonate cavity breccias are interpretated</div><div>as a terrestrial features, i .e. secondary surface products of physical and chemical weathering oftectonically disrupted carbonate-evaporite</div><div>sediments. The Upper Permian evaporites and carbonates of the central</div><div>Dinarides are sediments deposited in evaporitic conditions arround the edges of an epeiric marine basin which existed in conditions of a general regressive tendency and permanent coastal seawards progradation. The Upper Permian evaporites of central Dinarides are comparable with evaporites from the Bellerophon Formation from the Southern Alps, Italy.</div> |
