“…in: Bond et al, 2004;Riquier et al, 2006;Gerling et al, 1999a). The highest potential probably exists in the area of Poland, where these marly rocks reach thicknesses of more than 50 m with average TOC contents of about 2-3% (Joachimski et al, 2001). It should be noted that these latter TOC values were measured on immature/early mature shales.…”

Résumé -Ressources de gaz non conventionnels dans le Paléozoïque de l'Europe CentraleAlors que l'extraction du gaz naturel des gisements non conventionnels a fortement augmenté ces dernières dizaines d'années, un large potentiel de ressources reste inexploré dans les couches paléozoïques de l'Europe Centrale. Cet article présente, pour cette région, quelques aspects importants de la géologie des grès de faible perméabilité (tight gas sands), des gaz de schiste (gas shales) et du gaz de houille (coalbed methane, CBM). Les grès de faible perméabilité se trouvent surtout parmi les couches permiennes (Rotliegend) aux Pays-Bas et dans le nord de l'Allemagne, mais aussi dans les couches du Carbonifère supérieur. La production est déjà active dans quelques-uns de ces réservoirs. Pour l'avenir, le développement dépendra principalement de l'amélioration de la compréhension du gaz en place et de la distribution régionale de la porosité et la perméabilité qui, d'ailleurs, dépendent du faciès lithologique et la diagénèse. La recherche de gaz dans les roches argileuses, par contre, vient juste de commencer. Les roches argileuses mésozoïques dans le sud du bassin de Basse-Saxe (Lower Saxony Basin) sont des objets d'exploration prioritaire à cause de leur épaisseur, de leur maturité et de leur teneur en matière organique. Mais il existe d'autres séries intéressantes dans le carbonifère inférieur et des couches plus anciennes. Actuellement, un projet de recherche international vise à acquérir des données géologiques sur ces systèmes. La recherche du gaz de houille (CBM) a commencé dans la bassin de la Ruhr il y a une vingtaine d'années, mais avec un succès très limité à cause de faibles débits de gaz. En revanche, le captage de grisou des mines de charbon abandonnées a fourni de considérables quantités de gaz. De par la multitude des filons houillers et des conditions de maturité et de teneurs en gaz favorables, il existe dans cette région un potentiel considérable de gaz de houille.

“…These features are different from the P 3 d euxinic source rocks with very light sulfur isotopic composition. However, isotopically heavy organic sulfur was reported from euxinic basins across the Frasnian-Famennian boundary in the Kowala-Holy Cross Mountains, Poland [52] and during the Early Cambrian in the Tarim Basin [15], where organic sulfur is proposed to have been formed in sediments without significant amounts of H 2 S contributed from the overlying water columns. Therefore, the euxinic environment for the Lower Silurian shales cannot be ruled out.…”

Biomarkers and C and S Isotopes of the Permian to Triassic Solid Bitumen and Its Potential Source Rocks in NE Sichuan Basin

The potential parent source rocks except from Upper Permian Dalong Formation (P 3 d) for Upper Permian and Lower Triassic solid bitumen show high maturity to overmaturity with equivalent vitrinite reflectance (ER ) from 1.7% to 3.1% but have extractable organic matter likely not contaminated by younger source rocks. P 3 d source rocks were deposited under euxinic environments as indicated by the pyrite 34 S values as light as −34.5‰ and distribution of aryl isoprenoids, which were also detected from the Lower Silurian (S 1 l) source rock and the solid bitumen in the gas fields in the west not in the east. All the solid bitumen not altered by thermochemical sulfate reduction (TSR) has 13 C and 34 S values similar to part of the P 3 l kerogens and within the S 1 l kerogens. Thus, the eastern solid bitumen may have been derived from the P 3 l kerogens, and the western solid bitumen was likely to have precracking oils from P 3 l kerogens mixed with the S 1 l or P 3 d kerogens. This case-study tentatively shows that 13 C and 34 S values along with biomarkers have the potential to be used for the purpose of solid bitumen and source rock correlation in a rapidly buried basin, although further work should be done to confirm it.

Abstract. The reported placoderm remains from the Holy Cross Mountains, Poland, belong to the species Aspidichthys ingens Koenen, 1883. This study focuses on the material described in the past from Wietrznia Quarry but the new specimens were also collected form Kowala and Płucki localities. All specimens presented here differ from others described in the past, mainly by having smaller tubercles and possessing a distinctive crest in the anterior median part of the median dorsal plate, but did not allow the erection of a new taxon. Based on conodont assemblage, all specimens are attributed to a Frasnian age. Aspidichthys occurs in the middle to the upper part of the Frasnian (Palmatolepis punctata to P. linguiformis conodont zone) and is not found in the Famennian boundary. Described specimens also occur in a stepwise deepening environment caused by local synsedimentary tectonics.
