Spore-pollen analysis revealed the regional features of the vegetation communities for­ming. The percentages of all the AP and NAP taxa have been calculated of the total pollen sum AP+NAP (AP = pollen sum of trees and shrubs; NAP = pollen sum of upland herbs). The percentages of the pteridophytes and aqu­atics have been calculated of the total pollen sum. Indication of the pollen zones has been fulfilled according to the scheme of Makhnach et al. (1981) with some corrections based on more recent investigations.

Below is given a short description of the re­semblance and differences of the pollen zones beginning from the Sozhski Late Glacial.

DESCRIPTION OF THE POLLEN ZONES

MURAVIAN (=EEMIAN, MIKULINSKI) INTERGLACIAL

mr3 — Pinus-Betula-Quercus I Pinus-Betula-Carpinus

In general, a domination of Pinus and Betu­la as well as a significant participation of the NAP at the background of the permanent Quercetum mixtum occurrence are charac­teristic of this zone.

mr4 — Quercus-Pinus-Corylus

Maximum of Quercus along with an increas­ing percentages of Corylus and decreasing participation of Pinus is a common feature of this zone over the whole study area.

mr5 — Corylus-Tilia-Alnus

Arboreal species dominate while the herb plants are few. Synchronous maxima of Tilia and Alnus, preceded by the maximum of Corylus are characteristic of this zone. In most sections these events take place against a background of an increasing role of Carpinus.

mr6 — Carpinus

The principal feature of this zone is the maximum of Carpinus, the presence of Picea and, increase of its percentage by the end of the zone. In Knyazhevodtsy rare grains of Abies are met and Betula, Ulmus, Quercus are present.
