Absztrakt (kivonat)
The Paleozoic sequence of the Uppony mountains begins with a massive limestone complex of some hundreds meter thickness. The age is assumed to be Middle Devonian from the geological position below the Upper Devonian. A 1200—1400 m (according to K. BALOGH, 1964) thick sequence of shales with intercalations of mostly thin-bedded limestones (in the lower part frequent, in the upper parts more rare), diabases and tuffitic layers (limestone—shale complex) follows above the massive limestone complex. By the aid of conodonts the age of this limestone—shale complex could be determined to range from Upper Devonian up to the lower part Middle Carboniferous (Bashkirian). Above this complex the more than 900 m thick sandstone—shale complex with some lydites and manganese oxide, but without any limestones, follows. From the geological position immediately above a thin limestone layer with Bashkirian conodonts this complex should be Middle Carboniferous and it seems therefore to be the immediate base of the sandstone—shale complex of Bashkirian to Lower Moscovian age in the Bükk mountains. The upper part of the limestone—shale complex with only minor amounts of limestones and the sandstone—shale complex are regarded as equivalents of the "Hochwipfel Beds" of the Southern Alps as of similar sequence in the Dinaric Medvednica Mountains. The stage of preservation of the conodonts in the Uppony Paleozoic is the same as in the Triassic of the-Bükk mountains and Meliata-series as well as of parts of the Rudabánya Triassic. There are no differences in the metamorphosis between the Middle Devonian to Middle Carboniferous of the Uppony, the Lower Carboniferous of Ochtiná (Gemeric Palaeozoic) and the Triassic of Bükk mountains and Meliata series. Therefore an Alpine low grade metamorphosis of the Middle Devonian to Triassic beds is assumed in the studied area. The Hercynian orogeny seems to have little or no significance in the Uppony-Bükk area. No Hercynian metamorphosis or angular discoformities occur from the Middle Devonian to the Permian.
