gravity field

Purpose. The aim of this work is to trace large structural-tectonic elements within the Western region of Ukraine according to the characteristic signs of their manifestation in the anomalies of gravity and magnetic fields and the construction of regional tectonics schemes based on gravity and magnetometric materials. Methodology. The research method is based on a qualitative interpretation of the observed gravitational and magnetic fields.

Purpose. The aim of this paper is to clarify the deep structure and prospects of the oil and gas potential in the Kolomiya paleo-valley along the seismo-geotravers SG-I (67), which run along the line Nadvirna-Kolomiya-Otyniya-Ivano-Frankivsk. Seismo-geotravers SG-I (67) and partially covers the Borislav-Pokutsky cover, crosses the Sambor and Bilche-Volitsa zones, and enters the Eastern European platform.

Purpose.  The purpose of research is to study the effectiveness of anisotropic geological transformations Andreev-Klushina and confirm the relevance of the use of their improved versions to assist the qualitative interpretation of the anomalous potential fields. Methodology. Methods the study includes an analysis of algorithms and computer implementation of anisotropic transformations.

Main equation of the method of Euler deconvolution is considered. In contrast to the other works, the least squares method is used here to solve the equation. Depths of the geological objects of different shapes in the region of the Ukrainian Carpathians have been calculated.

Purpose. The purpose of the article is the interpretation of the gravity data with using the seismic data for revealing of zones of decompression with high porosity in the Visean carbonate of the Srebnenska depression (within Dnepro-Donetsk Basin). These zones may be associated with the development of organic Limestone massives, which are promising for hydrocarbon deposits. Methodology.

The construction of the regional altimetry-gravimetry quasigeoid is considered. This problem  was solved via the regional gravimetry quasigeoid transformation to the mean sea level given  by six satellite altimetry missions at time-period 1992-2007. Then the altimetry-gravimetry quasigeoid solution was selected for further computation of the gravity potential W0 for the Antarctic area. By this, a version of the vertical heights system in accordance with the gravity regional field is proposed.
