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.

pdf  Main features of sedimentogenesis of the Kularsky stage (T1 - T3k), Russia North-East
The peculiarities of the Triassic-Jurassic sedimentation process in the east of Russia are considered, its cyclic character is shown, region history three successive stages are established. The boundaries of the stages are determined by tectonic reasons; within the stages the cyclic character of sedimentogenesis and history is due to eustatic events. The characteristics of Kularsky stage (T1 - T3k) sedimentary history is given; the major types of sequences and sedimentologic models are presented.
