To better understand the coalification process, the authors have conducted numerous studies of the chemical structural composition of xylem tissue from gymnosperm wood and related woods that has been coalified to varying degrees. The studies presented in this paper examine the chemical nature of buried and coalified xylem tissue at the molecular level. To achieve this, the authors employed pyrolysis/gas chromatography (py/gc) and pyrolysis/gas chromotography/mass spectrometry (py/gc/ms). Pyrolysis techniques have been used to examine peat, coal, coalified wood, and related substances.
