The role of an oxidized lithospheric mantle in gold mobilization. [PDF]
Phanerozoic 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 ...

The subantarctic lithospheric mantle [PDF]
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.

Kimberlite genesis from a common carbonate-rich primary melt modified by lithospheric mantle assimilation. [PDF]
Diamond-bearing kimberlites were born from similar melts in the deep Earth and variably modified during ascent. Quantifying the compositional evolution of mantle-derived melts from source to surface is fundamental for constraining the nature of primary ...

Ductile Deformation of the Lithospheric Mantle
The strength of lithospheric plates is a central component of plate tectonics, governed by brittle processes in the shallow portion of the plate and ductile behavior in the deeper portion.

A metasomatized lithospheric mantle control on the metallogenic signature of post-subduction magmatism. [PDF]
Ore deposits are loci on Earth where energy and mass flux are greatly enhanced and focussed, acting as magnifying lenses into metal transport, fractionation and concentration mechanisms through the lithosphere.

Heavy oxygen recycled into the lithospheric mantle. [PDF]
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]
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).

Heterogeneous lithospheric mantle
The lithosphere is a thermal boundary layer atop mantle convection and a chemical boundary layer formed by mantle differentiation and melt extraction. The two boundary layers may everywhere have different thicknesses.

Earthquake rupture below the brittle-ductile transition in continental lithospheric mantle. [PDF]
The slow and inefficient deep Wyoming earthquake ruptured in the ductile regime of the upper mantle. Earthquakes deep in the continental lithosphere are rare and hard to interpret in our current understanding of temperature control on brittle failure ...

Making Cratonic Lithospheric Mantle [PDF]
The origin of cratonic lithospheric mantle has been attributed to either high‐pressure (5–7 GPa) melting in hot mantle plumes or low‐pressure (
