Layering of subcontinental lithospheric mantle

Science Bulletin, 2017
Recent seismic studies reveal a sharp velocity drop mostly at ∼70-100km depth within the thick mantle keel beneath cratons, termed the mid-lithosphere discontinuity (MLD). The common presence of the MLD in cratonic regions indicates structural and property layering of the subcontinental lithospheric mantle (SCLM).

The subantarctic lithospheric mantle [PDF]

open access: yesGeological 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.

The Role of Halogens in the Lithospheric Mantle

, 2018
The present chapter focuses on the still poorly known sources, distribution and fractionation of halogens in the oceanic and continental lithospheric mantle in intraplate and extensional tectonic settings, and in the deep cratonic sub-continental mantle that hosts diamonds and kimberlites.

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.
