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.
