pdf  Biochronology and lithology of the Triassic-Jurassic deposits of North-East Asia
A detailed description of key sections of the Triassic-Jurassic deposits in North-East Asia characterized by different tectonic origin is provided. The features of lithology have shown that the boundary between the Triassic and Jurassic period passes mostly in mono-facial strata that formed in a single sedimentation step of regional history (Yukagir) within a single climatic and biogeographic Boreal zone.
In botanical terms the change of bivalves shows that the boundary between the Triassic and Jurassic in North-East Asia is expressed in the disappearance of a number of Triassic genera and passing through this border of other genera; reappearing Jurassic phylogenetically species are closely related to the ancestral Triassic ones.

Key words: amonoidey, bivalves, Triassic, Jurassic, Rhaetian, Hettangian, North-East Asia.
