Abstract

The results of investigation of organic matter chemical structure of the coal-similar wood of Devonian and Jurassic geological periods by the methods of IR-, EPR-, chromate-masses-spectrometry and element analysis are presented. It is shown that the investigated samples are the products of the metamorphism of natural lignins, which confirms hypothesis about the important role of lignins in the processes of coal formation.
