Carbon isotope analysis of whole-coal and vitrinite from intruded coals from the Illinois Basin: No isotopic evidence for thermogenic methane generation

Autor: Harold D. Rowe, William W. Huggett, Mohammad W. Rahman, Susan M. Rimmer

Publikováno v: Chemical Geology. 453:1-11

Igneous intrusions into coals and organic-rich rocks may have contributed to global warming in the geologic past through the release of greenhouse gases. Evidence for a large release of thermogenic CH4 from the organics would include significant δ13

A suite of six naturally graphitized coals were separated by density-gradient centrifugation (DGC). The density profiles of anthracite and meta-anthracite samples show an average density increase from 1.50 g/mL to 1.93 g/mL with increased rank. Compo

Publikováno v: International Journal of Coal Geology. 69:144-152

Bituminous cobbles collected from the Fossil Forest site (Geodetic Hills, Axel Heiberg Island, Canadian Arctic) have been subjected to petrographic and geochemical characterization. Transmitted light microscopy and pyrolytic analyses indicate that th

Samples of vitrified and unvitrified Eocene woody plant tissues collected from the Fossil Forest site, Geodetic Hills, Axel Heiberg Island, have been characterized by TMAH thermochemolysis. All samples are gymnosperm-derived, are of very low maturity
