Regional and global chronostratigraphic correlation levels in the late Visean to Westphalian succession of the Lublin Basin (SE Poland)

Stanisław Skompski

Abstract


Five informal complexes with isochronous boundaries have been distinguished in the Carboniferous succession of the Lublin Basin. A description of their internal architecture and discussion of stratigraphical aspects of their boundaries are presented. Isochroneity of boundaries has been proved biostratigraphically and it results from the eustatic control on deposition of marine bands in the paralic succession. On the basis of different biostratigraphical zonations the distinguished boundaries are related to the international chronostratigraphical correlation levels, and then to the geochronological radiometric scales, mainly to the Ar/Ar scheme. In the analyzed interval of the Carboniferous (late Visean-Westphalian C) it is comparable with other, mostly U/Pb radiometric scales. Durations of the defined complexes are nearly equal (4-5 m. y.).
