Comparison of hydrocarbon compositions in a sequence of humic coals, cannel coals and oil shales from the Pictou Coalfield, Nova Scotia

[摘要] Thirty oil shale, cannel coal and humic coal samples from die Pennsylvanian Stellarton Group, Nova Scotia, Canada have been investigated in this study by means of organic geochemical methods including gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). Hydrocarbon compositions of the solvent extracts were found to vary significantly with lithology and facies.Analysis of the saturated hydrocarbon fractions revealed that the relative amounts of long-chain alkanes (>C 20 ) compared to those of short-chain alkanes (C 20 ) par rapport aux alcanes à chaine courte (
