Складено схематичну структурну карту донеогенової основи Закарпатського
прогину, на якій відтворено північний та південний борти, його центральну опущену ділянку, а також цілу низку поздовжніх (більш древніх) і поперечних (молодших)
порушень.
Донеогенова основа має блоково-насувну будову і складається з покривів Татро-
Вепорид, Гемерид і П’єнінського та накладеної на них мульди підгальського палеогенового флішу
The Transcarpathian Neogene deep, that is situated to the south-west of the Carpathian
mountain fold, is a superimposed structure being occurred in the different-age formations
(Paleozoic, Mesozoic and Paleogene).
In the territory of the Ukraine within its limits one can single out the Mukachevo and
Solotvyno parts which in particular distinguish themselves by different litho- and facies
varieties of the Miocene deposits and completeness of their section. Its two-storey structure
with the clearly marked lower and upper structural storeys (basement and molasse cover
correspondingly) is just one more peculiarity of the deep.
Executed studies find out the geological structure of the lower structural storey
(basement). On the basis of lithological-facies differences of the Paleozoic and MesoCainozoic rocks, complicated by block-thrusted structure, one can distinguish Pieniny,
Velykiy Bychkiv, Lesarnya, Zaluzh, Uzhhorod, Ruski Komarivtsi, Began, Sokirnytsia,
Shayany zones and a zone of the Central-Charpathian (Pidgalsky) Paleogene flysh.
A brief characteristic (lithological filling, depth of occurrence, space location) of
each of the above-mentioned tectonic units of the basement is stated in the paper. Schematic
images of structural-facies zoning of the basement (two geological intersectings) were
composed: along the line of Vyshkovo-Tereblya accross the Solotvyno deep and along the
line of Beregove-Zaluzh-Pryborzhavske through the Mukachevo deep, as well as schematic
structural map of the surface of Pre-Neogene folded basement of the Transcarpathian deep
in which the northern and southern edges, its central lowered area was reproduced as well
as a number of longitudinal (more ancient) and transverse (young) deformations. The PreNeogene basement of the Transcarpathian deep was established to be of heterogeneous
block-over thrust structure and is composed of Tatry-Veporidy and Limerydy covers,
partly of Pidgalsky Paleogene flysh, Pieniny cover and fragmentally of Magura and
Duklya covers. Here are widely distributed longitudinal, more ancient transverse and
newly formed diagonal dislocations. They are mainly faults, sometimes strike-slip faults
with very different amplitudes of dislocations that increase in the direction of central parts.
Structural units along the surface of the Pre-Neogene basement enable us to estimate the
thickness of the Neogene cover and to determine areas and individual structures promising
for gas. Raised blocks of the basement, as a rule, coincide with raised areas of Neogene
and the other way round, but in the strip of salt-diapir structures and areas complicated by
volcanogenous formations such coincidences may be lacking.
