Breakup Without Borders: How Continents Speed Up and Slow Down During Rifting

Geophysical Research Letters, 2019
Relative plate motions during continental rifting result from the interplay of local with far‐field forces. Here we study the dynamics of rifting and breakup using large‐scale numerical simulations of mantle convection with self‐consistent evolution of ...

Contrasting lithospheric geophysical structure of the Black Sea subbasins: Relevance to testing geotectonic models for this mega depression

Геофизический журнал, 2023
We present an integrated analysis of the geophysical parameters of the lithosphere of Black Sea basin obtained as a result of the interpretation of magnetic, gravity, thermal, deep seismic sounding and seismic-tomographic data.

Advances in Deformable Plate Tectonic Models: 2. Reconstructing the Southern North Atlantic Back Through Time

Geochemistry, Geophysics, Geosystems, 2022
The offshore rifted margins of the North Atlantic have a spatially complex crustal structure comprised of variable crustal morphologies, continental blocks, and inherited structures. Recently, deformable plate tectonic models have permitted the interplay

Evolution of rift-related cover-basement decoupling revealed by brecciation processes in the eastern Pyrenees

BSGF - Earth Sciences Bulletin, 2022
Breccias associated with tectonic, fluid and sedimentary evolution of rifted margins can provide information on a variety of processes reflecting the modes of extension.

Albitization evidences of Mesozoic carbonates: petrological study of authigenic albites in the northwest of the Bortziriak Cinco Villas Massif, eastern Basque-Cantabrian Basin

Geogaceta, 2023
The presence of authigenic Na-feldspars in sedimentary carbonate rocks is unusual and its origin is controversial in terms of genesis and timing. The use of optical microscopy, cathodoluminescence and in situ semi-quantitative EDX analysis techniques ...

Insights on Formation of the Gulf of Mexico by Rayleigh Surface Wave Imaging

Geochemistry, Geophysics, Geosystems, 2022
We used cross‐correlation of ambient noise records from seismic stations in the US, Mexico, and Cuba to extract dispersion data of Rayleigh surface wave.

Machine Learning‐Based New Earthquake Catalog Illuminates On‐Fault and Off‐Fault Seismicity Patterns at the Discovery Transform Fault, East Pacific Rise

Geochemistry, Geophysics, Geosystems, 2023
Oceanic transform faults connect spreading centers and are imprinted with previous tectonic events. However, their tectonic interactions are not well understood due to limited observations.

Rifting/spreading propagation interacts with preexisting transform faults: 3D geodynamic modeling

Frontiers in Earth Science, 2023
The divergent rifting/spreading centers and the strike-slip transform faults are the essential tectonic units on Earth, the dynamic evolution of which regulates the development of rifting/spreading basins. The propagation of rifting/spreading centers may

Tectonic structure and formation conditions of the submerged plateau and Socotra Island. Part II. Physical modeling

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2020
The authors studied the formation conditions and the character of deformations of the margin plateau and Socotra Island using the physical modeling. In experiments, a plate with elastic-plastic properties lying on a liquid base was subjected stretching ...
