| Description |
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. |
