Geoelectric model of the Earth’s crust and upper mantle of the Dniester-Bug megablock of the Ukrainian Shield

open access: yesГеофизический журнал, 2023
A network of long-period magnetotelluric and magnetovariational data (124 sites) in the period range of 9—16 to 2500—6400 s made it possible to explore the geoelectric structure of the Erth’s crust and upper mantle of most of the Dniester-Bug and ...

Seismic velocity structure of the Guerrero gap, Mexico [PDF]

open access: yesGeofísica Internacional, 2006
A two-dimensional velocity structure of the Guerrero gap was obtained by applying a damped least square method to hypocenters of local seismicity recorded by a telemetric network situated on the Guerrero coast, above Cocos plate subduction zone.

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 7, Page 1288-1308, July 2026.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Speed structure of the mantle under the Dnieper-Donets Depression and its surroundings. Part I

open access: yesГеофизический журнал, 2020
The article discusses the high-speed structure of the mantle under the Dnieper-Donets Depression (DDD). The solution obtained by the Taylor approximation of the solution of the three-dimensional seismic tomography problem is used.

Araguainha Dome, Brazil: A polygonal impact structure due to a complex pre‐impact regional structural framework

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 7, Page 1355-1385, July 2026.
Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

Late‐Stage Debris Flows Eroded Aeolis Mons in Gediz Vallis, Gale Crater, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract How the ancient climate of Mars transitioned to its current cold, hyperarid state is recorded by the sedimentary rocks preserved on its surface. Gale crater, the Curiosity rover landing site, is one such location, where the central mountain, Aeolis Mons, preserves an extensive sedimentary record. Curiosity has demonstrated that the Aeolis Mons

A Millennium of Coastside Occupation. Micromorphological Insights From the Indigenous Site of Las Estacas Cave, Tenerife

open access: yesGeoarchaeology, Volume 41, Issue 3, May/June 2026.
ABSTRACT The archaeological site of Las Estacas Cave (NW Tenerife, Canary Islands) preserves some of the earliest human occupations in Tenerife, dating to the 2nd century CE, spanning the entire pre‐European time range up to the 15th century. Using soil micromorphology, this study applies a geoarchaeological approach to reconstruct site formation ...

Holocene subaqueous landslide dynamics in the Lake Siljan‐Orsasjön Basin, south‐central Sweden

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Subaqueous landslide areas studied by multibeam bathymetry, sub‐bottom profiling and sediment coring reveal complex stratigraphies, suggesting mass movement events starting close to the area's deglaciation and up to very recent times. Abstract The Siljan‐Orsasjön Basin in south‐central Sweden hosts two prominent lakes.

Tectonophysical analysis and geodynamic interpretation of the three-dimensional geophysical model of the Ukrainian Shield

open access: yesГеофизический журнал, 2010
Geodynamic features of the Ukrainian Shield (USh) from Early Precambrian to Phanerozoic have been considered based on tectonophysical analysis of complex geophysical 3D model of the Shield, produced at the Institute of Geophysics of the National Academy ...
