Ivan Franko National University of Lviv,  Hrushevsky str. 4, UA – 79005 Lviv, Ukraine

It is the first time, when new reservoirs biogenic types in Devonian of Volyn– Podollia are described. They are initial moldic and secondary biogenic cavernous. Their formation is the  result of paleoorganisms life activity and postsedimentological transformation of their  skeletons and inner parts.

Key words: reservois, paleoorganisms, Devonian, Volyn–Podollia, oil-and-gas bearing region.

 

Indissoluble dispersed organics as criteria of Volyn–Podillia Devonian–Carbouiferous complex oil–and–gas–bearing capacity

 Hrushevsky str. 4, UA – 79005 Lviv, Ukraine

Geochemical maturity level determination of Volyn–Podillia Devonian–Carboniferous complex with palinoorictocenoses method is carried at first. By the concentration, composition, quantitative ratio of indissoluble dispersed organics (IDO), degree of preservation and palynomorphs color in Devonian–Carboniferous of the Volyn–Podillia of the East–European platform there zones (from the West to the East) can be singled out: the Western – is with anomalous composition of IDO; the Central – is with very bad preservation of liptinites elements; and the Eastern – is with the normal singling out of IDO.

Key words: indissoluble dispersed organics, oil-and-gas capacity, Devonian, Carboniferous, Volyn–Podillia.

A detailed paleontological investigation (by mollusks, foraminifers, ostracods) of Tarkhanian-Chokrakian deposits of the territory has been carried out.  For the first time shallow-water analogues of Tarkhanian deposits that are simular to Tomakovka beds of the Ukrainian shiels slope have been determinated for this region. The investigating region was situated rather near the sound between the Eastern Paratethys of the Chokrakian time and Mediterranean.

Key words: mollusks, foraminifers, ostracods, Tarkhanian, Chokrakian,  Miocene, Eastern Paratethys.

 

LOWER CARBONIFEROUS FORAMINIFERS ZONES OF LVIV-VOLYN COAL BASIN (ENDOTHYRANOPSIS COMPRESSUSARCHAEDISCUS KRESTOVNIKOVI–EOPARASTAFELLA AND ENDOTHYRANOPSIS CRASSUSEOSTAFFELLA PROIKENSIS)

Institute of the Geological Sciense of NASU

O. Gonchar str. 55 b, UA – 01601, Kyiv, Ukraine

In the Lower Carboniferous of Lviv-Volyn coal basin the foramenifers zones are distinguished at the first time. There are six zones. They are rather close to the suites in size. In cases when there was not enough material to distinguish zones, the layers of Limestone with the complexes of foraminifera were singled out. The stratotypes of zones are distinguished and their foraminifers characteristic are given by layers together with pictures of the most characteristic forms.

All the material is divided into three parts. In the first one the description of two zones is given together with their stratotypes, correlation plates and also some pictures of foraminifers. In this article the following zones are described: Endothyranopsis compressusArchaediscus krestovnikovi-Eoparastafella (zone I) ňŕ Endothyranopsis crassusEostaffella proikensis (zone II).

Key words: Lviv-Volyn coal basin, Lower Carboniferous, foramenifers zones, stratotype’s zones, correlation.
