Terra Nova, EarlyView.ABSTRACT We present novel 3D subsidence data enabling vertical movements' quantification during the early formation of the Pyrenean retro‐wedge. From Cenomanian to Turonian times, subsidence is relatively low (~26 ± 10 m/Myr), corresponding to a brief 10 Myr thermal re‐equilibration of the European lithosphere following the hyperextended rift episode ...

Earth's oldest mantle fabrics indicate Eoarchaean subduction
Nature Communications, 2016 Subduction is a main component of Phanerozoic plate tectonics, although the timing of initiation is controversial. Here, the authors present microstructural data from two 3.72 billion year old dunite lenses of Isua in Greenland, which suggest that ...

Timing of initiation of reverse displacement on the Taranaki Fault, northern Taranaki Basin: Constraints from the on land record (Oligocene Te Kuiti Group) [PDF]
, 2008 Structures associated with the wedge of basement overthrust into Taranaki Basin along the Taranaki Fault, are regarded as hydrocarbon plays and have been tested by drilling through the tip of the overthrust.

Patterns of Late Cenozoic exhumation deduced from apatite and zircon U-He ages from Fiordland, New Zealand [PDF]
, 2005 New apatite and zircon (U-Th)/He ages from the Fiordland region of New Zealand's South Island expand on earlier results and provide new constraints on patterns of Late Cenozoic exhumation and cooling across this region.

Frontiers in Earth Science, 2018 Three-dimensional analog experiments are employed to explore how self-sustaining subduction may initiate along an oceanic transform fault. The models include a realistic spatial distribution of plate thickness, strength, and buoyancy of the lithosphere ...

Mantle melting as a function of water content beneath back-arc basins [PDF]
, 2006 Subduction zone magmas are characterized by high concentrations of H_(2)O, presumably derived from the subducted plate and ultimately responsible for melting at this tectonic setting.

Post-ridge-subduction acceleration of the Indian plate induced by slab rollback
Solid Earth Sciences, 2018 The driving forces of plate motion, especially that of its sudden change over time, has long been debated. During the closure of an old ocean, the subduction process of the mid-ocean ridge provides valuable clues to quantitative evaluation of the driving

Thermal buoyancy on Venus: Preliminary results of finite element modeling [PDF]
Enhanced surface temperatures and a thinner lithosphere on Venus relative to Earth have been cited as leading to increased lithospheric buoyancy. This would limit or prevent subduction on Venus and favor the construction of thickened crust through ...

Origins of chemical diversity of back-arc basin basalts: a segment-scale study of the Eastern Lau Spreading Center [PDF]
, 2009 We report major, trace, and volatile element data on basaltic glasses from the northernmost segment of the Eastern Lau Spreading Center (ELSC1) in the Lau back-arc basin to further test and constrain models of back-arc volcanism.
