Water and Oxygen Fugacity in the Lithospheric Mantle Wedge beneath the Northern Canadian Cordillera (Alligator Lake)

Geochemistry, Geophysics, Geosystems, 2018
Assessing water contents of subduction zone mantle peridotites can gain insight into the compositions of slab‐derived fluids/melts and the active margin water cycle.

Mapping global kimberlite potential from reconstructions of mantle flow over the past billion years.

PLoS ONE, 2022
Kimberlites are the primary source of economic grade diamonds. Their geologically rapid eruptions preferentially occur near or through thick and ancient continental lithosphere.

Generation of Continental Lithospheric Mantle by Tectonic Isolation of Oceanic Plate

Geochemistry, Geophysics, Geosystems, 2022
Continental formation models invoke subduction or plume‐related processes to create the buoyant, refractory character of continental lithospheric mantle (CLM).

Plume‐Modified Lithosphere Mantle Controlled the Cenozoic Sediment Thickness in the Tarim Basin

Geophysical Research Letters
The Cenozoic sediments are very thick in the southwest Tarim Basin and very thin in the northwest, but what controls these variations is unclear.

Lithospheric heating by mantle plumes [PDF]

Geophysical Journal International, 1987
Summary. A broad topographic swell is associated with the Hawaiian hotspot. A kinematic model is developed assuming that downstream of the hotspot this swell is produced by lithospheric heating by a mantle plume. Material from the model plume flows radially in the asthenosphere and eventually heats the lower lithosphere.

Investigating the Antarctic Lithosphere Through Sp Receiver Function Analysis

Geochemistry, Geophysics, Geosystems
To better understand the lithosphere of Antarctica, we imaged its lithosphere‐asthenosphere boundary (LAB) and crust‐mantle transition using Sp receiver functions from teleseismic events analyzed at individual stations and with common conversion point ...

Mantle wedge serpentinization effects on slab dips

Terrestrial, Atmospheric and Oceanic Sciences, 2017
The mechanical coupling between a subducting slab and the overlying mantle wedge is an important factor in controlling the subduction dip angle and the flow in mantel wedge. This paper investigates the role of the amount of mantle serpentinization on the

Investigating the Effect of Lithosphere Thickness and Viscosity on Mantle Dynamics Throughout the Supercontinent Cycle

Geochemistry, Geophysics, Geosystems
The relationship between the lithosphere and the mantle during the supercontinent cycle is complex and poorly constrained. The processes which drive dispersal are often simplified to two end members: slab pull and plume push.

Imaging a Decratonized Lithosphere: A Case of the Eastern North China Craton

Geophysical Research Letters, 2022
During decratonization, the cratonic lithosphere mantle experienced composition transformation and thinning, which have been extensively studied in the North China Craton.
