Paly-nozones are biostratigraphic units with the unique, characteristic only for zonal sediments miospores' assemblage. The most important signs: 46 taxa are recorded - 31 transit and 24 key and typical species, 11 of which appear at the base of the Zone; and five species (Chelinospora timanica (Naum.) Loboziak et Streel, Cymbosporites magnificus (Mc Gregor) Mc Gregor et Camf., Re-tusotriletes radiosus Rask., Tuberculiretusispora subgibberosa (Naum.)

According to spreading peculiarities of key and characteristic species the following types of bio-units are identified: the Range-Zone (two units) and the Concurent-Range Zone (three ones). The main purposes of this study are to identify palynozones, distinguish their generalized description and to create a local scale of the palynological zonation - the vertical succesion of biozones. Lateral distribution - traced only in 12 wells of the Central and Northern parts of VPM EEP.

Due to facial-palynological research in the Famenian of the Volyn-Podillia margin of the East-European platform, five palynozones have been distinguished, characterized and their sequence has been determined.
General the with a thickness from 17 to 231 m are laterally widespreaded, recorded from a number of boreholes within Volyn-Podillya. The material for research consists of more than 450 samples, selected from 31 boreholes. The nature of the contacts: concordance bedding at the HV Zone and overlapped with disconformity by Carboniferous. Age determination and correlation with units of general Europian palynostratigraphic scales: correlate with the LE (lepidophyta-explanatus) Zone from Ozersk and Chovansk Horizons of the Pripyat Depression (Avkhimovitch et al, 1993; Kedo, Avkhimovitch, 1981; Avkhimovitch, Demidenko, 1985) and the upper part of the VCo (versabilis-cornuta) Zone, which defined in the Wocklum Stage (Famenian) of the Germany (Streel M. By the appearance or disappearance of characteristic and key species the following categories of biostratigraphic units are distinguished: two Range-Zones, three - Concurent-Range Zones.
Zones are based on the vertical range characteristics of the recorded taxa.

This is the first study to perform the standardized description of the biostratigraphic units determined by the palynological data for the Famennian of the Volyn-Podillia margin of the East-European platform. Palynozones are allocated laterally, traced in a number of boreholes within Volyn-Podillya.
In general, five palynozones are allocated in the Famennian. Miospores' composition of the Hymenozonotriletes versabilis - Archaeotriletes hamulus (VH) Zone Taxa Subdominant Accessory Key Convolutispora usitata, Hymenozonotriletes versabilis Grandispora distincta, G. They are local specialized biostratigraphic units with a set of palynological signs (a unique set of key, characteristic and transit taxa) that allow easy recognition of the different stratigraphic levels of the Famenian.
All palynozones are comprehensively documented thanks to numerous palynological data, characterized by a zonal spore assemblage, in the structure of which there are following categories of taxa: based on the vertical range characteristics - key, characteristic, transit ones; on the content - subdominant, accessory. facilis, Kedomonoletes glaber, Hymenozonotriletes cassis, Tuberculispora regularis, Geminospora golubinica Characteristic Lophozonotriletes scurrus, L. The method of presentation of biostratigraphic data has been updated.

It is the facies-varying complex of rocks, the stratification of which is very difficult because there are no faunal remains in the sediments (with the exception of the lower part).
Therefore, during the study of this stratum, the palynological method and the palynostratigraphic division are very important.
Palynozones with a thickness from 17 to 231 m are laterally widespreaded, recorded from a number of boreholes within Volyn-Podillya. Lateral distribution - widespread, traced in 19 wells. Typical section: Volyn region, borehole Litovezch 7,878-980 m. The nature of the contacts: concordance bedding at the CL Zone; in the Central part of the VPM EEP consonant overlapped of the L Zone (Upper Famenian) or in the south and north it is overlaid with disconformity by Lower Carboniferous; the base of the Zone is defined by the first appearance of Convolutispora usitata Playf., Grandispora dis-tincta (Naum.)
