A description is given of the Carboniferous from the Polish Lowland, with special stress laid on the Namurian whose most complete-development occurs in the Lublin Carboniferous basin. The stratigraphy of the Namurian deposits from that area is based on macrofauna - chiefly on goniatites. Most of the goniatite species, particularly the Upper Namurian ones, are here first reported from Poland. This helped to separate the Namurian B from the Namurian C and to distinguish the substages and goniatite zones known from the classical Namurian areas of western Europe. The lithology and the sedimentary processes at the Namurian in the Lublin basin are also reported. A description is, moreover, given of the Carboniferous deposits from north-western Po1and, the Sudetes and their forefield, as well as from the Silesia-Cracow basin and the Miechow depression. Some areas outside the Polish territory, i.e. Rugen and Mecklenburg going north-west, and the Lvov-Volhynia basin going south-east are discussed. The Namurian Paleogeography in Poland is presented in correlation with the development of the paralic Upper Carboniferous basins in the Subvariscan foredeep of western Europe. The probability of the existence of connections between the Namurian basin of Poland and western and eastern Europe is considered.
STRATlGRAPHY OF THE CARBONIFEROUS FROM BOREHOLES MARSZOWICE 1 AND KONIUSZA 1 (MIECHOW TROUGH, S POLAND) The stratigraphy is here discussed of Carboniferous deposits from two new boreholes in the vicinity of Slomniki (south-western part of the Miechow trough). In borehole Marszowice 1, on faunal evidence, the presence has been observed of the Lower Namurian and Upper Visean (Go γ and Go β ) in borehole Koniusza 1 of the Upper Visean (Go β ? and Go α ) perhaps also that of the Middle Visean.
THE CARBONIFEROUS OF THE ABRAMOW STRUCTURE SUMMARY A description is given of the characteristics of Carboniferous sediments observed in eight boreholes drilled by the Oil Research Survey within the Abramow structure (Lublin basin) in NE Poland. The macrofauna there has reliably suggested the presence of the Dinantian (Upper Visean) and the Silesian (Namurian and Lower Westphalian) overlying the Upper Devonian and underlying the Middle Jurassic.
The stratigraphy and correlation is here given of Lower Carboniferous sediments encountered in 12 borehole· profiles in the Wierzchowo area (Western Pomerania). The presence of the Tournaisian ( TnIa-Tn3 ) and of the Lower Visean ( VI ) has been observed on faunal evidence.
STRATlGRAPHY OF THE PALEOZOlC SEDIMENTS FROM BOBEHOLE STROŻYSKA 5 (MIECHOW TROUGH, S POLAND) The stratigraphy is given of the Paleozoic sediments from borehole Strozyska 5 (eastern part of the Miechow trough). Certain stratigraphic members of the Ordovician, Silurian, Devonian and Carboniferous are faunistically documented.
The Carboniferous of the Kock elevation Thirteen boreholes have been drilled between 1962 and 1971 in the vicinity of the Kock elevation. Ten of them have pierced the Carboniferous strata (Fig. 1). The stratigraphy of eight of these boreholes, drilled by the Oil Prospecting Enterprise, are being reported here. The remaining two boreholes were not accessible to the writers, but their basic stratigraphic features do not substantially differ from those here described. It has been observed that in the particular profiles the Devonian or the Silurian is overlaid by the Dinantian which commences with the tuffoidal series. This is transgressively overlaid by the Upper Vis¾an, while various Silesian members are covered by the Middle Jurassic.
The carboniferous of the Deblin structure Carboniferous sediments recorded by boreholes within the Deblin structure (Lublin basin, SE Poland) are assigned to the Upper Visean, Namurian and Lower Westphalian, on the basis of' macrofaunal and, partly, floral identifications.
The Lower Carboniferous observed in boreholes in the Chojnice region of Western Pomerania (NW Poland) is discussed. Strunian, Touraisian and Lower Visean deposits have been macrofaunistically determined.
The sequence of the Carboniferous deposits pierced by a series of boreholes within the Świdnik blocks near Lublin in eastern Poland (Lublin Coal Basin) begins with the Upper Vis¾an strata and continues to the Lower Westphalian. The goniatite content is used for biostratigraphic subdivision of these strata and it evidences the paralic conditions ranging until the Gastrioceras subcrenatum Zone of the lowermost Westphalian.
