Abstract: Global Tectonics and the Hydrocarbon Occurrence in the Alpino-Carpathian Arch

JIRICEK, RUDOLF

The author defined three hydrocarbon zones within the Alpino-Carpathian chain ( Jiricek, 1976 ). Outer methane zone is extended in the foredeep of the Czech Republic, Poland, the Ukraine and the Moldavian part of Romania. This zone changes laterally for the oil-gas zones in the East-South Carpathian territory on the East and in the Perialpine molasse on the West. The middle oil zone is connected with the Carpathian flysch, including the NE-part of Vienna basin basement. The inner methane zone is extended in the SE-part of the Vienna basin, in the NW-part of the Danube basin and in the Transcarpathian and Transylvanian basins.

According to the new pattern developed by Jiricek (1979) the Alpino-Carpathian nappes were moved to the foreland, but from the West to the East with the time delay, owing to oblique collision of plates. The origin of reservoir and seal rocks, tectonic structures, hydrocarbons and their migration and accumulation in the reservoirs were delayed from the West towards the East. The youngest hydrocarbon deposits in the foredeep: Bavaria (Chattian), U.Austria (Eggenburgian), L. Austria - S.Moravia (Karpatian), N.Moravia (L.Badenian), Poland-the Ukraine (L.Sarmatian), Moldavia (U.Sarmatian), Getic basin in Romania (Meotian-Pontian), Moesian Platform (Pontian-Dacian). Mostly hydrocarbon deposits in the inner methane zone: the Vienna basin (L.Badenian-U.Sarmatian), the Danube basin (M.Badenian), East Slovakia (U.Badenian-L.Sarmatian), the Transylvanian basin (U.Badenian-U.Sarmatian).
