Carapaces of the Dnieper-Donets Basin as a New Exploration Target

SPE Eastern Europe Subsurface Conference, 2021
Abstract New geological structures - displaced blocks of salt diapirs’ overburden - were identified in the axial part of the Dnieper-Donets basin (DDB) beside one of the largest salt domes due to modern high-precision gravity and magnetic surveys and their joint 3D inversion with seismic and well log data.

Gas Content and Structure of Coal in Donets Basin

Journal of Mining Science, 2018
The integrated study of coal is performed using methods of optical and electron paramagnetic resonances, infrared spectroscopy and Raman spectroscopy. It is found that gas content of coal is governed by the rank of coal and its material constitution as well as by the coal bed structure at the macro-, micro- and nano-levels which interwork.

Studies of coal balls of the donets basin

Review of Palaeobotany and Palynology, 1972
Coal balls are known in two coal basins of the Soviet Union viz. Donets (Middle Carboniferous) and Kuznets (Upper Permian). Coal balls are widespread in the Donets basin from Westfalian A to Westfalian D. Almost all the types described for America are represented. Plant remains in coal balls belong to different groups of plants — lycopods, articulates,

RELATIONSHIPS IN THE METAMORPHISM OF THE DONETS-BASIN COALS

International Geology Review, 1963
The degree of metamorphism in the Donets Basin coals increases from stratigraphically higher horizons to the lower ones. Also the change is gradual and in .any given seam runs parallel to the thickness of the coal-bearing strata from west to east and from the edge to the center.

Magmatism and Stages of the Tectonic Evolution in the Donets Folded Structure, Eastern Donets Basin

Geotectonics, 2018
The structure of the Donets Folded Structure underwent a complicated evolution, which included stages of extension, the origin of rift troughs, compression, collision, inversion uplifts, orogenesis, and stages of stabilization and neotectonic reactivation. The paper presents data on the regional tectono-stratigraphic Late Proterozoic–Cenozoic complexes

Basin evolution and coal geology of the Donets Basin (Ukraine, Russia): An overview

International Journal of Coal Geology, 2012
Abstract The Donets Basin is a major coal-mining district in eastern Ukraine and adjacent portions of Russia. It comprises the Donbas Foldbelt, which is the uplifted and compressionally deformed part of the Pripyat–Dniepr–Donets (PDD) Basin, and the significantly less deformed Western Donbas region.

FACTORS IN THE DEVELOPMENT OF CONSUMER SERVICES IN THE DONETS BASIN

Soviet Geography, 1978
Family-budget surveys in the Donbas city of Voroshilovgrad are used to analyze the impact of selected factors on the demand for consumer services. Families of white-collar workers tend to spend more for the repair of sporting goods and electric appliances than blue-collar families.

Paleozoic Source Rocks in the Dniepr-Donets Basin, Ukraine

71st EAGE Conference and Exhibition incorporating SPE EUROPEC 2009, 2009
The Dniepr-Donets Basin (DDB) is a major hydrocarbon province in eastern Europe. Moreover organic-rich sediments in the DDB may offer a shale gas potential. However, only limited data on source rocks are available.

Time and mechanism of formation of folding in the Donets basin

International Geology Review, 1977
The main anticlinal folds in the Donets basin arose in zones of deep-seated faults separating large, slightly disturbed basement blocks to which the synclines are confined. These blocks, in their descending and ascending movements, alternately passed each other, thus bending the sedimentary beds first on one then on the other side of the deep-seated ...

Structure, properties, and use of anthracites of the Donets Basin

Solid Fuel Chemistry, 2010
General characterization of anthracites of the Donetsk Basin (Donbas) in general and their specific features in the Eastern (Russian) Donbas are given, and data on their chemical composition, structure, and properties depending on the degree of metamorphism are presented, as well as correlation between different indicators of the metamorphic rank. Main
