Maturity determination of organic matter in coals using the methylphenanthrene distribution

Abstract The distribution of phenanthrene and monomethylphenanthrenes in extracts of 15 different coals was determined by gas chromatography. The maturity as measured by vitrinite reflectance varied from 0.53% to 1.29% R 0 , covering the maturity range normally associated with the “oil window” ( 0.5–1.2% R 0 ). p ]Principal component analysis followed by factor rotation reveals that coal maturity correlates only with the distribution of the mono-methylphenanthrenes and not with the relative abundance of phenanthrene. This implies a methylphenanthrene distribution fraction (MPDF) linearly related to vitrinite reflectance for coal with maturity within the oil window.
