For the first time, lithosphere deep structure was analyzed using RomUkrSeis profile. The study incorporated velocity, gravity and geoelectric models applying information about lithosphere-asthenosphere boundary, thermal magnetic field anomalies signs of modern activation. following features main layers Earth’s crust upper mantle were identified. In Apuseni Mountains, high-density heterogeneities can be interpreted as ophiolite complexes. detected deconsolidation NE Mountains part...
The calculations of thermal field parameters at oil and gas fields for the Chernihivskyi Lokhvitskyi blocks DDB allowed us to define geothermal gradient changes with depth. At all fields, there are wells stable gradients 19—21 °C/km, ones sharp changes. On block territory, these negative (the decreases 15—17 °C/km); between Kherson—Smolensk tectonic suture Pereiaslav-Khmelnytskyi—Pryluky Fault, both positive, southeast from it (at block) they exclusively positive (increases up 35—55 °C/km)....
We outline the way to GMT-Auto, an automated complex for interpreting potential fields. It includes three stages: 1995—2000, 2001—2009 and in 2010- present day. The work at each stage included solving direct problems creating software entering information presented on paper, outputting received data graphical format. In solutions gravimetry problem inhomogeneous randomly truncated vertical rectangular prism were given programs developed calculating gravitational effects a (3D Gravity)...
Magnetic, gravity, geothermal, seismic and tomographic data from the lithosphere were first jointly examined. A multidisciplinary interpretation has resulted in a new consistent model for lithospheric density, magnetic, thermal velocity heterogeneities. Faults of different orders crystalline crust have been mapped details. Large deep fault zones recognized. Among them is most prominent Odessa-Sinop-Ordu (OSO) zone, which played key role opening development Black Sea Depression. fundamental...
We present a new digital Moho depth map of the Carpathian-Pannonian region. The was produced by compiling discontinuity data, which were obtained interpretation seismic measurements taking into account results 2-D and 3-D integrated geophysical modelling. resultant is characterized significant Moho-depth variations. trends features in this region correlated with tectonic units.
Three-dimensional Earth’s crust density model of the central part Golovanevsk suture zone Ukrainian Shield at scale 1:50 000 has been given. Model calculations were carried out using automated complex GMT-Auto. The takes into account change in both laterally accordance with petrophysical data; and depth seismometry data. In this case; an abrupt one direction or another; inversion constant was taken consideration. rated bodies on surface basement defined based percentage ratio constituent...
Principles of operation have been set out for a program complex the potential fields automated interpretation (GMT-Auto) aimed at: 1) computer input automation images geologic-geophysical maps with subsequent transformation introduced data into digital form; 2) solving direct gravity, magnetic and thermal problems three-dimensional heterogeneous layers; 3) visualization three- dimensional geophysical models their fields. Application created facilitates hastens essentially process interpretation.
According to the data of three-dimensional density modeling at scale 1:200 000 peculiarity Earth’s crust structure Korsun-Novomirgorod pluton and Novoukrainka massif has been found as well distribution by depth lateral in granitoid massifs gabbro-anorthosites Ingul megablock were given detail. Density change within limits suture fault zones traced, their comparative characteristics given.

Within the Ingul Megablock of Ukrainian Shield, according to data three-dimensional density modeling, at scale 1 : 200 000, thickness conditionally allocated “granite”, “diorite”, “basalt” layers, which abroad have name upper, middle and lower crust, are determined their characteristic is given. In relation each layer total expressed in parts, four types crust distinguished: granite, diorite, leuco-basalt, basalt. Since composition Earth’s an important factor assessing prospects for...
Geological and geophysical data about the structure of Mukachevo Solotvyno sub-basins Transcarpathian Basin (TB), located in hinterland Outer Carpathians, are integrated adapted to modern ideas Carpathian realm geodynamics.

This paper presents a comprehensive analytical review of the various approaches to gravity modelling Earth’s crust Black Sea and adjacent territories. It is shown that even in using same thickness sedimentary layers whose total gravitational effect makes considerable contribution observed field results different authors do not coincide some cases contradict each other. The reason every researcher uses ad hoc reference density method reducing calculated curves. Therefore, an unified...
