“…8B). These results are similar to those obtained for the LCB by Kotarba and Clayton (2003) and Gola et al (2011), suggesting the low maturity of the organic matter. The lower maturity of coals than of clastic rocks may be explained either by (1) their biodegradation or (2) by a significant enrichment in organic matter, which causes limited contact with clay minerals, responsible for acceleration of the catalytic reactions.…”

“…The geochemical studies of Kotarba and Clayton (2003) and of Gola et al (2011) indicate that the dominant compound in bituminous coal from the LCB is organic material composed of higher plant matter. This dominance is confirmed by the present study.…”

“…The presence of gammacerane, a biomarker, has been taken to suggest hypersaline conditions (Haven et al 1989) or stratification of the water column during organic matter deposition (Sinninghe Damstè et al 1995). According to Kotarba and Clayton (2003) the presence of gammacerane in coal does not imply hypersaline conditions. They suggested that its presence can be connected to other, unknown sources, or to the provenance of the parent organisms from different, salinity-independent depositional environments.…”

“…Kotarba and Clayton (2003) provided isotopic analyses and the analysis of molecular fossils from several coal samples from the LCB (coal bed no. 382), revealing a prevalent input of higher plant organic matter and a low stage of thermal transformation in the material (Kotarba and Clayton 2003). Gola et al (2011) dealt with the geochemical analysis of organic matter in bituminous coal from bed no.…”

ABSTRACT:Gola, M.R., Karger, M., Gazda, L. and Grafka, O. 2013. Organic geochemistry of Upper Carboniferous bituminous coals and clastic sediments from the Lublin Coal Basin (Poland). Acta Geologica Polonica, 63 (3), 425−442. Warszawa.Bituminous coals and clastic rocks from the Lublin Formation (Pennsylvanian, Westphalian B) were subjected to detailed biomarker and Rock-Eval analyses. The investigation of aliphatic and aromatic fractions and Rock-Eval T max suggests that the Carboniferous deposits attained relatively low levels of thermal maturity, at the end of the microbial processes/initial phase of the oil window. Somewhat higher values of maturity in the clastic sediments were caused by postdiagenetic biodegradation of organic matter.The dominance of the odd carbon-numbered n-alkanes in the range n-C 25 to n-C 31 , high concentrations of moretanes and a predominance of C 28 and C 29 steranes are indicative of a terrigenous origin of the organic matter in the study material. This is supported by the presence of eudesmane, bisabolane, dihydro-ar-curcumene and cadalene, found mainly in the coal samples. In addition, tri-and tetracyclic diterpanes, e. g. 16β(H)-kaurane, 16β(H)-phyllocladane, 16α(H)-kaurane and norisopimarane, were identified, suggesting an admixture of conifer ancestors among the deposited higher plants. Parameters Pr/n-C 17 and R dit in the coal samples show deposition of organic matter from peat swamp environments, with the water levels varying from high (water-logged swamp) to very low (ephemeral swamp). Clastic deposits were accumulated in a flood plain environment with local small ponds/lakes. In pond/lake sediments, apart from the dominant terrigenous organic matter, research also revealed a certain quantity of algal matter, indicated, i.a., by the presence of tricyclic triterpanes C 28 and C 29 and elevated concentrations of steranes.The Paq parameter can prove to be a useful tool in the identification of organic matter, but the processes of organic matter biodegradation observed in clastic rocks most likely influence the value of the parameter, at the same time lowering the interpretation potential of these compounds.The value of Pr/Ph varies from 0.93 to 5.24 and from 3.49 to 22.57 in the clastic sediments and coals respectively. The microbial degradation of organic matter in both type of rocks and during early stages of diagenesis is confirmed by a high concentration of hopanes, the presence of drimane homologues, bicyclic alkanes and benzohopanes. Moreover, bacteria could also have been connected with the primary input of organic matter, which is shown by the presence of e.g. C 30 neohop-13(18)-ene.

The spatial and temporal scales and the geometry of fluid pathways in a collisional orogen are investigated using stable isotope analysis (O, C, and H) C values that are buffered by the Helvetic metasediments, which suggests that these veins formed in a closed system from a locally derived CO 2 -rich fluid. The fluid in equilibrium with C-type veins has depleted δ 13 C values similar to mantle-CO 2 , while the intermediate δ
