New data on the Carboniferous corals of the Donets Basin

Palaeoworld, 2010
Abstract Additional data are given here on the taxonomic diversity and distribution of the Carboniferous rugose and tabulate corals of the Donets Basin (Ukraine). Keyserlingophyllum obliquum (Keyserling, 1846) was recorded in the Tournaisian part of the section for the first time.

GEOLOGICAL AND GEOTECTONIC UNITY OF THE DONETS BASIN AND THE DNIPROV-DONETS FALLS

Mining Geology & Geoecology, 2022
On the basis of medium-scale mapping of the pre-Mesozoic surface of Donbas and the southeastern part of the DDZ, the use of the results of seismostratigraphic and gravimetric works, the analysis of scientific research, publications and innovative hypotheses, the geological and geotectonic unity of Donbas and the DDZ is substantiated.

The Donets Basin (Ukraine/Russia): coalification and thermal history

International Journal of Coal Geology, 2002
The Donets Basin (Donbas) is one of the major late Paleozoic coal basins in the world. The Donbas Foldbelt is an inverted part of the Donets Basin characterized by WNW-ESE-trending folds and faults. The age of basin inversion is under discussion. Large parts of the Donets Basin host anthracite and meta-anthracite.

Palaeozoic source rocks in the Dniepr–Donets Basin, Ukraine

Petroleum Geoscience, 2010
ABSTRACT The Dniepr–Donets Basin (DDB) is a major petroleum province in Eastern Europe. In order to understand the regional and stratigraphic distribution of source rocks for the dominantly gas-prone petroleum system, 676 fine-grained rocks from 30 wells were analysed for bulk parameters (total organic carbon (TOC), carbonate, sulphur, RockEval).

TECTONIC INVERSION OF THE DNIEPER-DONETS BASIN

2021
The structural deformations of the sedimentary cover of the Dnieper-Donets basin (DDB) of the stages of platform tectonic activation in the zone of its articulation with the Donets Foldbelt (DF) were studied. Based on the structural analysis of the geocarting materials of the territory of the Western Donets Graben (WDG), using field definitions of the ...

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. Superposition of

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
