NEW DATA OF LOWER EOCENE
NUMMULITES FINDINES IN SOUTH-WESTERN PART OF PRECASPIAN DEPRESSION
Institute
of Geological Sciences NASU
Description and imaging of 5 large foraminifers species discovered in
Lower Eocene deposits (Bakhchisaray stage) are given for the first time for the
south-western part of Precaspian depression. They are: Nummulites planulatus, N. aquitanicus, Discocyclina archiaci, D. pratti, D. Nummulitica. The discovery of nummulites at this territory is
widening the arial of their distribution in the Northern nummulitite province
and anowing to correlate with deposits of the same age of nearrange
territories.
Lower carboniferous foraminifers zones of
Lviv–volyn coal basin
(Betpakodiscus cornuspiroides and Rectocornuspira regulariformis)
Institute of the Geological Sciense of NASU
In the Lower Carboniferous of Lviv-Volyn coal basin the
forameniferal zones are distinguished for the first time. Four of the six
distinguished zones were described in two previous articles. Other two
Serpukhovian zones – Betpakodiscus cornuspiroides and Rectocornuspira
regulariformis are described in this article. The stratotypes of these zones
are distinguished in the article and some photoplates with pictures of the most
characteristic foraminifera (in systematic sequence) are given.
Viviparidae OF
pRYDUNAY SUITE
Melitopol University
The 8 species of Pliocene Viviparidae from Prydunay suite are
discribed.
New data about paleontological
haracteristic

Precarpathian
Ivan Franko National University of Lviv
By the new data from wells drilling in Precarpathian Fredeep new
information about Jurassic bivalvia is given.
SOME SPECIES OF THE SUBORDO PHYLLOCERATINA FROM
JURASSIC OF THE PIENNINE ZONE OF UKRINIANE CARPATHIANS
Ivan Franco National University of Lviv
5 species of Ammonoidea (suborso PHYLLOCERATINA)
are paleontologically described.
They are founded in Jurassic from Piennine zone of Ukrainian Carpathians at
first. There are: Phylloceras asisbekovi Kakhadze, Phylloceras serum Oppel, Calliphylloceras cf. subdisputabile Rostovcev, Calliphylloceras
heterophylloides Oppel, Holcophylloceras zignodianum Orbigny .
THE
OSTRACODES PHYLOGENESIS OF THE SUBORDER CYPRIDOCOPINA (OSTRACODA, CRUSTACEA)
Geological Science Institute
of NASU
The ostracodes phylogenesis of the suborder
Cypridocopina from
the Cambrian to the Holocene was studied. Distinctive features of the
morphology of a fossil carapace and ontogeny of ostracodes have been taken as a
basis for phylogenetic reconstructions. The schemes of phylogenetic relations
for families, subfamilies and genera have been created.
V. Karazin National University of Charkiv
An essential dependence of ostracod shell composition on ontogenetic,
filogenetic and diagenetic factors has been determined. It has been show that
the relation of mineralogic/organic components and heterogeneousty of
microelement distribution in ostracod shells should be taken into account for
biostratigraphical subdivision of deposit sequence and sedimentation –
conditions estimation.
The paper presents the data objecting against the correlation of the Mayachkian
suites with deposits of the Kozakhurian regional stage.

Pecularites
of systematic composition and ecology of Cenomanian mollusks and brachiopods of
the platform regions of Ukraine are presented.
Stratigraphical distribution of
Gastropods in Cretaceous sediments, Volyn-Podillya region
The study of the systematic composition and stratigraphical distribution of Gastropods in
cretaceous deposits (Volyn-Podillya region) has been allowed to find out here
such complexes: Albian, Cenomanian, Campanian-Lower Maastrichtian and Upper
Maastrichtian. The analysis of the systematic composition of Gastropods of cretaceous deposits of Volyn-Podillya region, Donbass, Anglo-Parisian
basin and Polish-German basin has shown significant similarity of their
specific composition. This similarity
allows talking about their distribution in one paleobiogeographical province.
THE NEW FINDINGS OF
PERIDINIALES IN THE AUTOCHTHON UPPER CRETACEOUS DEPOSITS OF POKUTTIA-BUKOVYNA
CARPATHIANS
Lviv branch of Ukrainian
State Geological Research Institute
It
is described the complex of Peridiniales, spores and pollen of terrestrial
plants in the Upper Cretaceous deposits of Lopushnia-5 well (4319–4324 m).The peculiarity of this complex is advantage of
marine Peridiniales which are spread in the Late Cretaceous time of Europe
different regions (France, Germany, Poland), Australia and Russia and also in
the Cenomanian in England and presence of great amount of angiosperms plants
pollen.
PROBLEMS OF STRATIGRAPHIC CORRELATION OF LOWER
CRETACEOUS DEPOSITS (STAVCHANY SUITE) IN THE PRECARPATHIANS
Lviv branch of Ukrainian State Geological Prospecting
Institute
In the stratigraphic scheme of Lower Cretaceous deposits of the
Precarpathians (1993) is present only Stavchany suite (of the Upper
Berriasian-Hauterivian). Determination of age range of Stavchany suite
accumulations remains problematic question of stratification in the mentioned
region in conformity with microfaunal data of V.H. Dulub (1972).
In the northwestern part of Precarpathians the Lower Cretaceous deposits
are represented in the main by carbonate formations (Stavchany suite) and in
the southeast – chiefly by terrigenous variegated rocks of Barremian-Aptian age
in accordance with palynologic data. In connection with this it is proposed to
single out the deposits in the southeast of the region in the separate local
stratigraphic unit – Pokuttia suite.
Stratigraphic correlation and establishment of the Precarpathians Lower
Cretaceous formations age boundaries is problematic and actual question at
present because these deposits contain hydrocarbon pools.
PALEONTOLOGICAL

The stratigraphical studying viewing of Lower Cretaceous of
the Cremea plain is given. Biostratigraphical charakteristic of stages,
substages, ammonite zones are supplemented and detalized by own microfaunal
investigations.

Ivan Franco National University of Lviv
In the article the stratification of the sections into
petrogenetic layers, their correlation, changes of the coal composition and
peat-forming phytocenoses and formation paleoecology of the seam d4 at the peat stage of
coalification are described.
