Their age was corroborated by the palynologic and paleobotanic data. The detailed biostartigraphic data were obtained in the area"Pioneer"for the first time. The coal-bearing strata were correlated with those from the sections of the Arkhara-Boguchan brown coal field and the stratotype of the Tsagajan Formation of the Bureya Belogor’ye.展开更多

The paper contains descriptions of three sets of spores and pollen taken from Shadoronsk and one set from Undino-Dainsk biostratigraphic horizons. It also provides comparison characteristics of palynocomplexes that belong to Middle and Upper Jurassic deposits in East Transbaikalye with coeval complexes in Siberia and Kazakhstan and provides geological sequence of their formation.展开更多
