The Relation between the Stages of Organic Matter Transformation in Coals and Mineral Components of Inter-Coalarkosesandstones (an the Example of Lena and Irkutsk Basins)

The research has first revealed the direct relation between the secondary changes in the coalinclosing rocks and the metamorphosis degrees of the coals themselves. Geochemical balance has been proved to develop within the “coal organic matter – sandstone mineral matter” system in tectonic environments providing combination of low-temperature propylitization in arkose sandstones and caustobiolith coalification ranks of G and F.
