In the context of the master 's thesis the Triassic stratigraphic sequence on Mt. Vernar (2225 m) was investigated. Mt. Vernar is located in the Julian Alps, which are structurally (tectonically) part of the Southern Alps. About 100 m below the summit on the eastern side of the mountain is the horizon of the Uggovitz breccia. The thickness of the horizon varies laterally from 30 to 150 m. Laterally with breccias occurs red nodular limestone. Above the breccias and the red nodular limestone is a massive platform limestone of the Schlern Formation. In the thesis, the detailed stratigraphic sequence of the eastern side of Mt. Vernar is described. The Uggovitz breccia occurs in this sequence. The composition of the clasts was described in detail. The breccia consists mainly of carbonate clasts. Their analysis showed that they were mostly formed as limestones on the carbonate platform and were later eroded as clasts from a relatively elevated block. Based on the fossils, mainly foraminifera, we concluded that the clasts are of Anisian age. Volcanic clasts eroded from rhyolite lava are also visible. Carbonate sandstone occurs as thin layers between breccia beds. By analyzing the overlying red nodular limestones and the fossils contained therein and comparing them with other known cases, we found that the limestone was deposited in a shallow water marine environment. By analyzing samples from the uppermost massive Schlern Formation we found that carbonate production continued on the Ladinian platform after the half-graben was filled with sediments. Based on an analysis of the sediments, it is interpreted that a half-graben was formed as a consequence of the extension at the end of the Anisian and filled with sediments of the Uggovitz breccia. Thereafter, the shallow water sedimentation of red nodular limestone continued after that carbonates were produced on the relatively uplifted Ladinian carbonate platform. The stratigraphic succession fromVernar is similar to other known and described cases from the Julian Alps (Prisojnik), Kamnik-Savinja Alps (Ute, Križevnik), Carnian Alps, Balaton Highlands, the outer Dinarides and the Dolomites.
