Thinning and destruction of the lithospheric mantle root beneath the North China Craton: A review

Earth-Science Reviews, 2019
It is widely accepted that the lithosphere beneath the eastern portion of the North China Craton (NCC) has suffered extensive thinning and destruction since the Mesozoic.

The continental lithospheric mantle: characteristics and significance as a mantle reservoir

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2002
The continental lithospheric mantle (CLM) is a small-volumed (ca. 2.5% of the total mantle), chemically distinct mantle reservoir that has been suggested to play a role in the source of continental and oceanic magmatism. It is our most easily identifiable reservoir for preserving chemical heterogeneity in the mantle.

Mantle and sub-lithosphere mantle gravity maps from the LITHO1.0 global lithospheric model

Earth-Science Reviews, 2019
Abstract Methods for a spherical harmonic analysis and synthesis of global gravitational and lithospheric structure models are applied to compile the mantle and sub-lithospheric mantle gravity maps. Both gravity maps are then interpreted and assessed by means of their accuracy.

Thermochemical lithosphere differentiation and the origin of cratonic mantle

Nature, 2020
Cratons record the early history of continental lithosphere formation, yet how they became the most enduring part of the lithosphere on Earth remains unknown1. Here we propose a mechanism for the formation of large volumes of melt-depleted cratonic lithospheric mantle (CLM) and its evolution to stable cratons.

Mantle flow and the evolution of the lithosphere

Physics of the Earth and Planetary Interiors, 1993
Abstract The evolution of the lithosphere is mainly controlled by time-dependent forces due to (1) plate tectonic processes and (2) sublithospheric mantle flow. Plate tectonic processes like continental collision may provide strong thermal disturbances and, after completion, may trigger secondary convection beneath the lithosphere.

Lithospheric Mantle Deformation beneath the Indian Cratons

The Journal of Geology, 1999
The nature of deformation of the deep continental roots beneath the Archean-Early Proterozoic terrains opens the question whether these ancient terrains have had stable roots since the Precambrian or whether recent plate motions have deformed them. In view of this, we make an attempt to study the thermal structure beneath the cratonic regions of the ...

Role of the lithosphere in mantle convection

Journal of Geophysical Research: Solid Earth, 1988
Plate geometry and kinematics generally reflect the mechanical properties of the solid lithosphere rather than those of the fluid mantle underneath, and plate formation and subduction account for most of the heat transport from the Earth's interior. Correspondingly, mantle convection models must incorporate a stiff but mobile boundary layer, like the ...

A subduction origin for komatiites and cratonic lithospheric mantle

South African Journal of Geology, 2004
We present a model in which the generation of komatiites in Archaean subduction zones produced depleted mantle residues that eventually formed the highly depleted portions of the Kaapvaal lithospheric mantle. The envisioned melting process is similar to that which has formed boninites in Phanerozoic subduction zones such as the Izu-Bonin-Mariana arc ...
