ABSTRACT: The origins of coal macerals: Recent progress and future directions

Scott, Andrew C. , Royal Holloway, University of London, Egham, Surrey, United Kingdom

Coalified organic materials have been traditionally classified using coal petrographic techniques. Increasingly coal petrographic data from both coals and dispersed organic matter are being used for palaeoenvironmental interpretations. Coal macerals based upon morphology and reflectance characteristics are not always equatable to specific plants, plant organs or plant tissues. Recent work combining studies of the chemistry (including Pyrolysis-gas chromatography-mass spectrometry, Previous HitFourierNext Hit Previous HitTransformTop Infra-Red spectroscopy and 13C Solid State Nuclear Magnetic Resonance) and morphology (including Transmission and Scanning Electron Microscopy) of modern and fossil plant and animal tissues has highlighted some problems of the application of coal petrology to palaeoenvironmental interpretations including the origin of oil-prone coals. Recent studies of liptinites (cuticles, spores, resins), vitrinites (wood, periderm) and inertinites (charcoals) are highlighted. New directions in research will be discussed.
