Dispersed cuticles and conducting tissue of Sphenophyllum BRONGNIART from the Westphalian D of Kalinovo, Donets Basin, Ukraine

open access: yesGeologia Croatica, 2015
Upper Westphalian coals are usually rich in organic-matter of different plant taxa, including gymnosperms. The assemblagefrom Kalinovo (Eastern Ukraine) is exceptional in being dominated by Sphenophyllum, both cuticles andconducting tissues ...

A Novel Approach to Tsunami Prediction Using Ambient Noise‐Derived Green's Functions

open access: yesGeophysical Research Letters, Volume 52, Issue 5, 16 March 2025.
Abstract Conventional tsunami simulations rely on accurate bathymetric data, posing challenges in regions lacking such information. We introduce a novel approach using ambient noise interferometry to derive empirical Green's functions of infragravity waves from noise correlation functions (NCFs) extracted from a 10‐year Deep‐ocean Assessment and ...

Distribution of thermal characteristics in the north-west part of the near-axial zone of the Dnieper-Donets basin

open access: yesДоповiдi Нацiональної академiї наук України, 2019
The geothermal gradient and heat flow distributions on fields at the axial part of the south-western side of the Dnieper-Donets basin are analyzed. The distributions of geothermal parameters on gas and oil fields are compared.

Low Geomagnetic Paleointensity in the Mid‐Part of the Kiaman Superchron

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 1, January 2025.
Abstract The Kiaman Reversed Superchron (∼260–318 Ma) is the longest known period of single geomagnetic polarity in Earth history (∼55 million years). It is associated with anomalously low dispersion of virtual geomagnetic poles and some high estimates of Earth's dipole moment.

Craniological analysis of the muskrat (Ondatra zibethicus) from different river basins of Ukraine

open access: yesTheriologia Ukrainica, 2023
The paper presents the results of a comprehensive craniological analysis of muskrats (Ondatra zibethicus Linnaeus, 1766) from five river basins of Ukraine: Dnipro (Lower Dnipro, Kherson Oblast), Snihurivka (irrigation canal, Mykolaiv Oblast), Danube ...

Aulacogens, the Donets Basin (Eastern Ukraine, Southwestern Russia), and the new classification of rifts: Towards a proper terminology [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2012
Some intra-cratonic basins are traditionally called “aulacogens”. This term has persisted in the geoscience literature since its invention by Soviet geologists in the mid-20th century before the triumph of the plate tectonics, but its meaning ...

Macrofloral biostratigraphy reflects late Carboniferous vegetation dynamics in the Nord‐Pas‐de‐Calais Coalfield, France

open access: yesPapers in Palaeontology, Volume 10, Issue 2, March/April 2024.
Abstract The Nord‐Pas‐de‐Calais Coalfield is formed by an almost continuous succession of upper Carboniferous deposits, from which an extremely diverse macroflora has historically been described. Recent evidence has highlighted a clear pattern of changing species diversity, showing some differences from what is seen in other coalfields of Variscan ...

Alkaline magmatism from the Lublin–Baltic area of Poland (SW slope of the East European Craton)—Manifestation of hitherto unrecognized early Carboniferous igneous province

open access: yesTerra Nova, Volume 36, Issue 1, Page 77-88, February 2024.
Abstract Our study of boreholes, seismic survey and magnetic data from the region between the Baltic Basin and the Lublin Basin indicates the existence of numerous buried intrusions and effusive complexes, most of them unnoticed so far, together with a few igneous massifs. They are of alkaline character and developed in a time span of c. 348 to 338 Ma.

Determination coefficient of oil saturation with low-resistivity reservoirs according to neutron characteristics of the environment

open access: yesМінеральні ресурси України, 2016
The deposits that occur in the central part of the Dnieper-Donets basin and have low resistivity values were considered hopeless in oil saturation as investigated incomplete set of log wells. The paper presents a method for determining coefficient of oil

Geoelectric models of the earth's crust of Ukraine by the results of the magnetotelluric studies using new methods of inversions

open access: yesГеофизический журнал, 2016
Application of 1D anisotropic inversion (using methods of stochastic and directional decomposition analysis) and 3D inversion (by thin layer) to magnetotelluric data in the territory of Ukraine allowed to prove quantitatively the existence of conductive ...
