Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance We show high-resolution P and S images of the subducted Indian mantle lithosphere, which has been torn into four main pieces. The tearing provides a unified mechanism for (i) Late Miocene and Quaternary rifting, (ii) mantle earthquakes in ...

Mapping a hidden terrane boundary in the mantle lithosphere with lamprophyres
Nature Communications, 2018 Lamprophyres represent hydrous alkaline mantle melts that are a unique source of information about the composition of continental lithosphere. Here the authors use isotopic compositions of lamprophyres to map a hidden terrain boundary and an unknown ...

African cratonic lithosphere carved by mantle plumes [PDF]
Nature Communications, 2020 AbstractHow cratons, the ancient cores of continents, evolved since their formation over 2.5 Ga ago is debated. Seismic tomography can map the thick lithosphere of cratons, but its resolution is low in sparsely sampled continents. Here we show, using waveform tomography with a large, newly available dataset, that cratonic lithosphere beneath Africa is ...

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.

Water in Hawaiian peridotite minerals: A case for a dry metasomatized oceanic mantle lithosphere
Geochemistry, Geophysics, Geosystems, 2015 The distribution of water concentrations in the oceanic upper mantle has drastic influence on its melting, rheology, and electrical and thermal conductivities and yet is primarily known indirectly from analyses of OIB and MORB.

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

Patched removal of the mantle lithosphere under orogens: A systematic numerical study
Frontiers in Earth Science, 2023 Delamination or convective thinning could cause large-scale and complete removal of the mantle lithosphere under orogens. However, geological and geophysical observations suggest that patched removal of the mantle lithosphere has occurred in some orogens,

Passive margin inversion controlled by stability of the mantle lithosphere
, 2021 Contractional deformation of passive continental margins may resemble early stages of induced subduction initiation. Mechanical instabilities are required to permit underthrusting of the oceanic plate.
