Abstract

Phyterals of the coals of two thick coal seams (vitrinitic for the most part) near the USSR Mongolia border are described here: the "Ulug" of the Ulugkhem basin and the "Chadan" of the Chadan deposit. A three-stage hierarchical classification of the studied phyterals has been worked out. Within this classification we distinguish groups (according to the plant organs), subgroups (on the basis of the plant tissues) and individual phyterals. One can draw a conclusion that the Jurassic coal-forming vegetation in Tuva was rather a shrubby (probably, an undershrub) or an herbaceous one, than an arboreal forest.
