Titanium and water-rich metamorphic olivine in high-pressure serpentinites from the Voltri Massif (Ligurian Alps, Italy): evidence for deep subduction of high-field strength and fluid-mobile elements [PDF]
, 2014 Titanium- and water-rich metamorphic olivine (Fo 86-88) is reported from partially dehydrated serpentinites from the Voltri complex, Ligurian Alps. The rocks are composed of mostly antigorite and olivine in addition to magnetite, chlorite, clinopyroxene ...

Coupling SPH and thermochemical models of planets: Methodology and example of a Mars-sized body [PDF]
, 2017 Giant impacts have been suggested to explain various characteristics of terrestrial planets and their moons. However, so far in most models only the immediate effects of the collisions have been considered, while the long-term interior evolution of the ...

Ultramafic xenoliths from the Bearpaw Mountains, Montana, USA: evidence for multiple metasomatic events in the lithospheric mantle beneath the Wyoming craton [PDF]
, 2004 Ultramafic xenoliths in Eocene minettes of the Bearpaw Mountains volcanic field (Montana, USA), derived from the lower lithosphere of the Wyoming craton, can be divided based on textural criteria into tectonite and cumulate groups. The tectonites consist

Origin of Pyroxenite-Peridotite Veined Mantle by Refertilization Reactions: Evidence from the Ronda Peridotite (Southern Spain) [PDF]
Journal of Petrology, 2008 The Ronda orogenic peridotite (southern Spain) contains a variety of pyroxene-rich rocks ranging from high-pressure garnet granulites and pyroxenites to low-pressure plagioclase–spinel websterites. The ‘asthenospherized’ part of the Ronda peridotite contains abundant layered websterites (‘group C’ pyroxenites), without significant deformation, that ...

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Since the Mesozoic, much of the eastern China lithosphere was removed through thermo‐mechanical erosion and delamination, yet the effects on the overlying crust remain unclear. The Tanlu Fault Zone (TLFZ), the region's largest lithosphere‐scale weakness, offers a natural laboratory to assess crustal responses to lithospheric destruction.

Geophysical characterisation of the ocean–continent transition at magma-poor rifted margins [PDF]
, 2009 Geophysical characterisation of the ocean-continent transition (OCT) at magma-poor riftedmargins has focused primarily on the determination of P wave velocities using wide-angleseismic techniques. Such experiments have shown that the OCT is heterogeneous,

Magnetic Signature of Oceanic Transform Faults and Their Fracture Zones
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Oceanic transform faults (TFs) offset mid‐ocean ridges, juxtaposing different‐aged crust and causing fracture zones (FZ) crossing ocean basins. Mounting evidence challenges the consensus that TFs are conservative plate boundaries, instead supporting the existence of extensional tectonics and two phases of magmatism.
