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 ...

A metasomatized lithospheric mantle control on the metallogenic signature of post-subduction magmatism [PDF]
Nat Commun, 2019 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.

The subantarctic lithospheric mantle [PDF]
Geological Society, London, Memoirs, 2021 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]
Sci Adv, 2020 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
Annual Review of Earth and Planetary Sciences, 2023 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.

Heterogeneous lithospheric mantle
, 2021 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.

The Zagros core: Deformation of the continental lithospheric mantle [PDF]
Geochemistry, Geophysics, Geosystems, 2012 The Zagros of Iran form one of the youngest collisional orogenic belts on Earth. At shallow depths, shortening across the Zagros is accommodated by folding in the sediments, high‐angle thrust faulting in the basement and thickening of the lower crust, but how shortening is accommodated by the lithospheric mantle has been uncertain largely because the ...

Earthquake rupture below the brittle-ductile transition in continental lithospheric mantle [PDF]
Sci Adv, 2017 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 ...

Geochemistry, Geophysics, Geosystems, 2018 The role of lithospheric architecture and the mantle in the genesis of iron oxide copper‐gold (IOCG) deposits is controversial. Using the example of the Precambrian Gawler Craton (South Australia), which hosts the giant Olympic Dam IOCG deposit, we ...

Making Cratonic Lithospheric Mantle [PDF]
Journal of Geophysical Research: Solid Earth, 2018 The origin of cratonic lithospheric mantle has been attributed to either high‐pressure (5–7 GPa) melting in hot mantle plumes or low‐pressure (
