Data for a paleographic reconstruction of Transdanubia, Hungary, at the end of Paleozoic time

In Mecsek Mts. and Balaton Highland a well studiable characteristic red sandstone group consisting of basic conglomerate with subjacent layers as well as cross-laminated red sandstone, covered by Seisian fauna-bearing formations can be found. In spite of some good criteria of the identifiableness, the conciliatory attempts have produced numerous contradictions during last hundred years. L. LÓCZY sen. and J. BÖCKH had agreed in the stratigraphic identity of both sequence, nevertheless they ranged them into Permian and Triassic, respectively. E. VADÁSZ had choosen the Permian period, but he did not recognize the character of the main conglomerate of Mecsek Mts. therefore he was unable to do an acceptable comparison between both sequence. Leaving the lithostratigraphic identity out of consideration lastly K. BALOGH and A. BARABÁS ranged the red sandstones of Balaton Highland and Mecsek Mts. into Permian and Triassic, respectively, similarly to L. LÓCZY Sen. and J. BÖCKH. The author presents a paleogeographic sketch pointing out possibility of a lithostratigraphic and cronostratigraphic correlation in the mentioned region
