Journal of Geophysical Research: Solid Earth, Volume 127, Issue 10, October 2022., 2022 Abstract Two‐decades of onshore‐offshore, ocean‐bottom seismometer, and passive‐source data are integrated to obtain high‐resolution 3‐D constraints on the architecture of the Nankai subduction zone. Our model reveals large along‐strike variability in the width of the outer‐forearc, with the crustal backstop (VP ≥ 5 km/s) extending within 50 km of ...

Bashkirian Rugosa (Anthozoa) from the Donets Basin (Ukraine). Part 12. Concluding considerations [PDF]
, 2022 A detailed analysis of the upper Viséan, Serpukhovian and Bashkirian Rugosa of the Donets Basin confirms their Mississippian/Pennsylvanian turnover during the Eumorphoceras / Homalophyllites-Hudsonoceras Zone, as postulated earlier (Fedorowski 1981a ...

Pseudogzheloceras—a new genus of Carboniferous nautilids (Cephalopoda) from Europe and North Africa
Geo&Bio, 2021 Analysis of morphology, stratigraphic and geographic distribution of the group of nautilid species, mainly from the Westphalian of Western Europe, and the Bashkirian and Moscovian of the Donets Basin (Eastern Ukraine) made it possible to establish a new ...

Origin, Accretion, and Reworking of Continents
Reviews of Geophysics, Volume 59, Issue 3, September 2021., 2021 Abstract The continental crust is unique to the Earth in the solar system, and controversies remain regarding its origin, accretion and reworking of continents. The plate tectonics theory has been significantly challenged in explaining the origin of Archean (especially pre‐3.0 Ga) continents as they rarely preserve hallmarks of plate tectonics.

Cephalopods from the Middle Carboniferous of the Donets Basin (Luhansk region, Eastern Ukraine)
Geo&Bio, 2018 Six forms of cephalopods are described from Middle Carboniferous deposits (Man-drykinka and Mospinska Formations) of the Donets Basin. The collection includes three nautiloids: a new species Millkoninckioceras udovichenkoi sp.

Journal of Geophysical Research: Solid Earth, Volume 126, Issue 6, June 2021., 2021 Abstract We derive the 3‐D S‐wave velocity structures of sediments and upper crust in the region off Ibaraki at Japan Trench subduction zone by applying ambient noise tomography to a dense array of short‐period ocean bottom seismometers (OBSs). The cross‐spectra were calculated using 27 or 142‐day continuous seismic data, and the phase velocities of ...

Population and distribution of beavers Castor fiber and Castor canadensis in Eurasia
Mammal Review, Volume 51, Issue 1, Page 1-24, January 2021., 2021 A century ago, overhunting had reduced Eurasian beaver Castor fiber populations to c. 1200 animals in scattered refugia from France to Mongolia. Reintroductions and natural spread have since restored beavers to wide areas of their original range. The population has more than tripled since the first modern estimate in 1998, to c. 1.5 million.

AMMONOID BIOSTRATIGRAPHY OF THE BASHKIRIAN (PENNSYLVANIAN) IN THE DONETS BASIN
Collection of Scientific Works of the Institute of Geological Sciences of the NAS of Ukraine, 2022 The article provides a rationale for beds with ammonoids in the Bashkirian and lower part of the Moscovian of the Donets Basin, Ukraine. In the lower part of the Bashkirian (Voznesenskian, Feninskian, Manuilivskian and Blagodatnenskian horizons), the Beds with Homoceras (correlated with the Homoceras Genozone), Beds with Reticuloceras (correlated with ...
