FEATURES OF RELIEF OF THE BORZHAVA RIVER MIDDLE FLOW AREA AND THEIR CONNECTION WITH GEODYNAMICS AND SEISMOTECTONICS

With attraction of the newest (until 2010–2022 inclusive) geological-geophysical and geodetic data geological-tectonic construction, features relief Borzhava River middle flow area (Ukrainian Transcarpathians) were analyzed, including peculiarities morphology river valley, their connection with geodynamics seismotectonics territory is traced. In interval between Keretsky Dovge villages flows in valley south – southeast direction southwestern slopes Folded Carpathians northeastern Vygorlat-Guta volcanic ridge, tracing near-surface localization Transcarpathian deep fault zone geological structures (fault-suture, i.e. contact zones tectonic depression Carpathians). village terns to southwest crosses ridge this Velyki Komyaty village, its here associated rupture discontinuities diagonal zone. The place connected junction fault-suture Onok height Velykyy Sholles which surround it from east, are influence Vynohradiv meridional Oash faults. parth studied area, under mountain ranges Kuk Palenyy Grun` ridges, a relatively (40–55 km) seismic activity was discovered, related zones, first dips northeast Carpathians, second (its tilted subfault) eastern Solotvyno depression. Also regular, (2 perceptible earthquakes since beginning 2023) (mainly at depths pre-Neogene basement (2–6 km)) demonstrated (along fault-block trough fold-thrust Carpathians) by (orthogonal mini-graben structure) conjugated it, more submeridional Shalanky-Irshava (slightly sigmoid plan) Petrovo-Ardanovo genesis specified seismicity analyzed point view combination "alpine" (thrust-subduction crustal sedimentary strata modern so-called multi-tiered "crocodile" tectonics), present "terrain" (shift east end Alkapa terrane superimposed, low-amplitude process) "asthenolitic" ("spreading" convective asthenolite Pannonia) components late Neogene ("post-magmatic", up 5–7 million years ago) regional geodynamic process.
