Foraminiferal and palynological zones have important regional implications providing well-constrained biostratigraphy of the Anabar-Lena region.

Combined sedimentological, geochemical studies and ecological analysis of microfossil associations (foraminifera, marine and terrestrial palynomoprhs) allowed the palaeoenvironmental reconstructions for the marginal area of the Anabar-Lena palaeosea and coastal land areas.",
