Contribution of prof. Ya. O. Kul¢chytskyi to study of
useful minerals of the Ukrainian Carpathians has been analysed. Some
individual publicathions and collective monodraphic works have been devoted to
these questions: “Geology and Useful Minerals of the Ukrainian Carpathians” (ð. ², 1976;
ð. II, 1977), “Tectonics and Metallogeny of the Soviet Carpathians”
(1988). The merit of the scientist in study of combustible minerals (gas, oil,
menilitic argillites) and natural waters is great. These scientific works are
urgent and useful till now.

Lviv, Ukraine
Western Ukraine can serve as a good test area for paleogeodynamic reconstructions. An ancient
platform and different-age epi-orogenous zones framed by the Carpathian alpides
are joined here. Numerous attempts to explain their modern structure from the
standpoint of the lithospheric plate tectonics cannot be recognized as
successful. The pulsing Earth hypothesis is in a better accordance with an
available geological-geophysical material on the region. However, even this
hypothesis cannot solve some cardinal aspects of the structure and the Alpine
development. The list of the most important aspects is given in the
publication.
Key words: paleogeodynamics, lithosphesic plates, circular
structures, passive rifting, polymorphic transformations, extension,
compression, pulsation, Carpathians.

It has been proved that
two generations of greenstone belts have been distinguished owing to incorrect
interpretation of radiogenic age data. On the basis of correlation of crossing through greenstone
structures of Middle-Predniprovian and
Western-Preazovian geoblocks of the Ukrainian shield their similarity has been
revealed. The available data of

reflect synchronism of structures formation.

Transformation
of the kainite under heating has been
investigated on the
basis of X-ray analysis results.
Kainite crystalline structure as was determined is destructed in temperature
interval about 100-300°C.
At the expense of destruction products langbeinite, sylvite and magnesium
hydroksochloride forming take place as well as H2O and HCl
exudation.
Under
heating of the kainite to 600°C
such destruction products as langbeinite and sylvite are stable while magnesium
hydroksochloride disintegrates into MgO and HCl.

The whole Mesozoic complex (Jurassic-Cretaceous) of the examined
territory was considerably eroded in pre-Miocens time, that is why in the north-western part of
Bil'tche-Volyts'ka zone the Creataceous deposits are completely absent and the Miocens rocks lay directly on the
eroded Jurassic surface. Not only karst
reservoirs which associate with pre-Miocenic erosion but also ones
connected with the pre-Albian continental break have been developed in the
Upper-Jurassic-Neocomian carbonate complex of the Carpathians foreland. The forecast resources of oil and gas associated with up to
Albian karst can be revealed in the eastern part of the foreland where the
premises for their screening by the Albian clay deposites have been existed.
Key words: carbonates,

A complex analysis of data on the structure and
geodynamics of the Transcarpathian lithosphere has been conducted. On the basis
of the comparison of DSS and seismology data with geothermal, geoelectric,
tectonophysical, gravimetric ones and by introducing geological, geodetic and
geomorphological data, the nature and origin of low-velocity channels in the regional core have been determined. It was shown that such
subzone in “bazalts” is a subzone of increased (due to considerably increased
depth temperatures, caused by a high mantle heat flow) rock thermoplasticity. As against it the subzone in “granites” is the highly fracturing disconsolidated
fluidosaturated zone, caused by a constant tectonic loading on the background
of transition from high depth temperatures and correspondingly relatively
elastic rocks to lower temperatures and hence more risid and brittle rocks. Low-velocity channel in “granites” is a source of
geothermal energy, gold-polymetallic compounds, rare-earth and other valuable
elements as well as a zone of probable hydrocarbon traps. It is a key zone in
local seismotectonic process in which due to fluid pore stress regulation the seismic territory regime can be controlled
and destructive earthquakes can be prevented or their negative consequences can
be reduced.
Key words: Transcarpathans, geodynamics, low-velocity channel,

The position of Beregovo hill
contry magmatogene structures has been caused by their arranging for the zones
of crust increased permeability and for the raising of basement blocks. The
conditions necessary for displays of magmatism,arise first of all in fault structures, which were formed under action
of regional compression. The network of sub-latitudinal and sub-meridional
faults in Transcarpathians can be considered as the dynamically connected
combination of shear- and tension zones.
Caused by such combination the arrangement of volcanic centers has
been revealed in Beregovo hill country. The influence of regional and local
fields of stress on magmatogene structures of the central type was showed in
formation of various genesis breaks network.
The main task of research –
the division of all the shear fractures paragenesises depending on stress
character, which have caused their occurrence. The orientation in space of vectors
of the principial normal stress is determined, which action has resulted in
occurrence of certain orientation fracturing. The systems of the connected
fractures have been allocated, which formation is connected to action of stress
regional field.
Key words: magmatogene structures of central type,shear
fracture, caldera, stereogram, axis of
principal normal stress, vector, systems of connected fractures.

nappes the methods
of the structural analysis and
paleotectonic reconstruction’s
are base. We used them for study of pre-frontal part of nappe
Zelemianka in the quarry Pivdennyi
(southern borderland of Hrebeniv
village). Plicate and disjunctive dislocations of the different orders are
advanced in the section of quarry
walls. Multistage of deformation process has
resulted in transformation of
high orders pre-fault dissuring in zones of tectonic crushing and autoclastic melange. On the basis of the diagrams of
fissuring the local tectonic stress fields within the limits of a section are allocated. The alternation of
the intense condition of different orientation confirms discrete behaviour of
deformation process.
