Speed structure of the mantle under the Dnieper-Donets depression and its surrooudings. Pt. II
This work is a continuation of the analysis of the velocity structure of the mantle beneath the Dnieper-Donets Basin and its environment, which includes the north of the Ukrainian Shield and the south of the Voronezh crystalline massif (based on the ...

Pseudogzheloceras—a new genus of Carboniferous nautilids (Cephalopoda) from Europe and North Africa
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 ...

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 ...

Origin, Accretion, and Reworking of Continents
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)
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.

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
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.
