Formation conditions and stratigraphy of Carboniferous coal deposits of the Siberian Platform

Litbological, paleogeographic, and paleontologic characteristics of the Siberian Platform indicate three stages in the geological development of the region and evolution of its organic world: Early, Middle, and Late Carboniferous, corresponding to the Lower, Middle, and Upper series of the Carboniferous system. Deposits of the lower series, separated as the Anganehan horizon. Include the Anganchan, Kazach'ya, and Krasnognr'yevka suites and lower portions of the Apsekan, Brus, Fat'yanikha, and Kondromo suites. Deposits of the middle series are assigned to the Tushama horizon, which includes the Tushama, Yangoto, Miirma, and Khattynngynakh suites and the Upper portions of the Apsekan, Brus, Fat'yanikha, and Kondromo suites. Formations of the upper series (the Kata horizon) include the Rudnaya, Anaklt, Listvyazhnoye, Kata, and Chokhchuolu suites.—Authors.
