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.

Analog and Numerical Modeling of Rift‐Rift‐Rift Triple Junctions

Tectonics, 2022
AbstractRift‐Rift‐Rift triple junctions are key features of emergent plate boundary networks during fragmentation of a continent. A key example of such a setting is the Afar triple junction where the African, Arabian and Somalian plates interact. We performed analog and numerical models simulating continental break‐up in a Rift‐Rift‐Rift setting to ...

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.

Rifts in rafts

Soft Matter, 2023
Particle rafts floating on expanding liquid substrates exhibit velocity-dependent failure morphology and provide an accessible model system for studying cluster formation and material failure across many scales from the microscopic to the celestial.

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.

Rifting continents

, 2022
Abstract. Continental rifts can form when and where continents are stretched. If the driving forces can overcome lithospheric strength, a rift valley forms. Rifts are characterised by faults, sedimentary basins, earthquakes and/or volcanism. With the right set of weakening feedbacks, a rift can evolve to break a continent into conjugate rifted margins ...

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
