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

However, on condition of spreading permafrost rocks this is conjugated with certain ecological risk just as from the transport network objects so for the objects themselves. A special attention is paid in the paper to considering of problems of projecting and constructing railways on the Udokan ridge.展开更多
