Heavy oxygen recycled into the lithospheric mantle. [PDF]
Sci Rep, 2019 AbstractMagmas in volcanic arcs have geochemical and isotopic signatures that can be related to mantle metasomatism due to fluids and melts released by the down-going oceanic crust and overlying sediments, which modify the chemistry and mineralogy of the mantle wedge.

Lithospheric mantle buoyancy: the role of tectonic convergence and mantle composition. [PDF]
Sci Rep, 2019 AbstractPlate subduction and delamination, two key processes driving plate tectonics, are thought to be controlled by the buoyancy of the lithospheric mantle relative to the underlying asthenosphere. Most mantle delamination models consider a lithospheric density higher than the asthenosphere to ensure negative buoyancy (slab pull).

The role of an oxidized lithospheric mantle in gold mobilization. [PDF]
Sci AdvPhanerozoic orogenic gold mineralization at craton margins is related to the metasomatism of the lithospheric mantle by crustal material. Slab subduction transfers Au from the crust to the metasomatized mantle and oxidizes the latter to facilitate the mobilization of Au into mantle melts. The role of volatiles in the mobilization of Au in the mantle is

Breakup of strong cratonic lithosphere causes extensive magmatism at continental margins [PDF]
Scientific ReportsExtensive magmatism and Large Igneous Provinces (LIPs) may form at continental margins during continental breakup. While high mantle temperatures and geochemical fertility (such as plume activity) are typically considered the causes of magmatic ...

The subantarctic lithospheric mantle [PDF]
Geological Society, London, Memoirs, 2021 Abstract We present a summary of peridotite in the Subantarctic (46–60° S) surrounding the Antarctic Plate. Peridotite xenoliths occur on the Kerguelen Islands and Auckland Islands. The Kerguelen Islands are underlain by a plume, whereas the Auckland Islands are part of continental Zealandia, which is a Gondwana-rifted fragment. Small amounts

Imaging a Decratonized Lithosphere: A Case of the Eastern North China Craton
Geophysical Research Letters, 2022 During decratonization, the cratonic lithosphere mantle experienced composition transformation and thinning, which have been extensively studied in the North China Craton.

Joint modeling of lithosphere and mantle dynamics elucidating lithosphere‐mantle coupling [PDF]
Geophysical Research Letters, 2008 We provide new insights into the lithosphere‐mantle coupling problem through a joint modeling of lithosphere dynamics and mantle convection and through comparison of model results with the high resolution velocity gradient tensor model along the Earth's plate boundary zones.
