Abstract
The Buntsandstein in Europe was deposited in various independent basins which are situated up to several thousands of km apart. The basins of the German facies are located in Middle Europe, Spain, and Bulgaria, whereas the Buntsandstein areas in Hungary, Austria and neighbouring countries belong to the Alpine facies, and the Tatra Mountains in Poland represent the Carpathian facies. While the Mid-European Triassic Basin has a very large extension, Bulgaria is characterized by comparatively smaller basins. The Buntsandstein columns in the Triassic basins in Bulgaria exhibit a pronounced similarity of the evolution of fluvial style to that in the Mid-European Buntsandstein. Characteristic lithogenetical elements such as blue-violet calcrete palaeosols, aeolian dune sands and Brӧckelbank carbonate breccias allow a palaeoenvironmental correlation of the Buntsandstein in Bulgaria with that in Middle Europe. The megacycles of the evolution of fluvial style thus permit a large scale lithostratigraphic connection of the Buntsandstein in both areas. The most important Buntsandstein basins in Bulgaria are Teteven Anticlinorium, Iskar Valley, Vitoša Mountains, Belogradčik area, Petrohan Pass, Sviti Ilija Heights and Trojan Pass. The Buntsandstein profiles in these basis are in parts of the sections quite comparable to those in Eifel-Pfalz-Saar area and Upper Franconia/Oberpfalz (Germany FRG), Holy Cross Mountains (Poland), Sudetes (Poland and Czechoslovakia. Mecsek Mountains (Hungary) and South Devon (England) in the Mid-European Triassic Basin and adjoining areas. Significant examples of the comparability of the evolution of fluvial style and palaeoenvironmental history of the Buntsandstein over long distances between Bulgaria and Middle Europe include Iskar Valley (Bulgaria) and Eifel Saar area (Germany, FRG), with various parts of the Eifel thus being the closest comparable examples to most of the Bundsandstein successions in Bulgaria. The Buntsandstein in Bulgaria can in most areas be stratigraphically divided into lower conglomerates, Middle Sandstones, Upper Sandstones and Mudstones, and terminal Mudstones. The boundary between Middle Sandstones and Upper Sandstones and Mudstones can be correlated with the boundary Middle Upper Buntsandstein in the German Basin.
