Abstract
Peculiarities of the distribution, morphological features, geological localization, and formation conditions have been considered for unique coal beds (thickness more than 50–100 m). It has been revealed that the genesis of such beds is related to extremely long-term (tens to hundreds of thousand years) stabilization periods of formation conditions of primary peat deposits. A significant role of the peat self-compaction is demonstrated. Principal types of coalfields with very thick beds are distinguished. Localization criteria (position in the section along with paleotectonic and paleogeographic controls) are presented for the most widespread types.
