Structural and Chemical Features of Organic Matter in Carbonized Wood of the Devonian and Jurassic Periods

摘要

The results of studies of the chemical structure of organic matter in Devonian and Jurassic carbonized wood using IR, ESR, and GC-MS techniques along with elemental analysis are presented. It is shown that the examined samples consist of metamorphism products of natural lignin, which confirms the hypothesis of the key role of lignin in coal formation.
