Study of the time evolution of the lithosphere [PDF]

The behavior and mechanical properties of the lithosphere were studied. This is a prerequisite to an understanding of the mechanisms and processes that occur in the Earth's mantle, which are masked by the lithospere. Geoid heights derived from the GEOS-3

Mountain Building or Backarc Extension in Ocean‐Continent Subduction Systems: A Function of Backarc Lithospheric Strength and Absolute Plate Velocities

Journal of Geophysical Research: Solid Earth, 2019
The crustal structure of overriding plates in subduction settings around the world varies between a wide range of deformation styles, ranging from extensional structures and backarc opening as in the Tonga or Hellenic subduction zone to large, plateau ...

Slab‐Mantle Interaction During Subduction Initiation: Constraints From Trace Element and Sr‐Nd‐Pb Isotope Systematics of Boninite and Other Magmas and Metamorphic Sole in the Oman Ophiolite

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Late Cretaceous Oman ophiolite includes a series of volcanic rocks generated during the transition from spreading ridge to protoarc associated with subduction initiation. We analyzed major and trace elements and Sr, Nd, and Pb isotope compositions of lavas and dikes of the protoarc stage, especially boninites. We also analyzed amphibolites

Lithospheric plate tectonics and mass extinctions of biological species

IOP Conference Series: Earth and Environmental Science, 2021
Abstract The merging of lithospheric plates and the formation of supercontinents are considered to be the main causes of global species extinctions within the Earth’s biosphere. Under those conditions, the factor of geographic isolation is diminished and interspecies competition is accelerated, allowing for the survival of the best ...

Mantle Transition Zone Topography in New Zealand From Teleseismic P $P$‐Wave Receiver Functions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The geology of New Zealand has been shaped by tectonic plate interactions driven by mantle convection over the past 60 million years, but the effects of these interactions on the transition to the lower mantle are not yet well understood. We analyze 10 years of teleseismic P $P$‐wave receiver functions using common conversion point stacking to

Origin of the Bulge Topography Within Caloris Basin, Mercury

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Caloris basin on Mercury has a massive circular bulge topography imprinted with unique fault sets. A variety of deformational processes have been proposed to have influenced their formation, including both global contraction and basin evolution, as well as the deposition and weight of the volcanic infill.

Evolution and Provenance of the Polish Rotliegend in the Southern Permian Basin

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The Southern Permian Basin (SPB) has been extensively explored for ore deposits. However, a comprehensive evaluation of the remaining copper potential, specifically for sediment‐hosted stratiform copper system, remains lacking. This study applies goSPL, an open‐source landscape and stratigraphic evolution model, to reconstruct the Permian rift‐

Edge‐modulated stagnant‐lid convection and volcanic passive margins

Geochemistry, Geophysics, Geosystems, 2007
The initial oceanic crust along volcanic passive margins is a factor of ∼3 greater than that of typical oceanic crust (20 versus 6–7 km). Convection driven by the edge of the continental lithosphere may cause mantle material to circulate through the ...

Some geophysical constraints to dynamic processes in the Southwestern Mediterranean

Annals of Geophysics, 1996
The total tectonic subsidence, thermal state and seismotectonic regime have been analysed to better constrain the dynamic processes which originated the basins of the Southwestern Mediterranean.
