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

open access: yesGeochemistry, 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.

Mantle wedge serpentinization effects on slab dips

open access: yesTerrestrial, 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

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

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

Reconciling the shadow of a subduction signature with rift geochemistry and tectonic environment in Eastern Marie Byrd Land, Antarctica [PDF]

open access: yes, 2016
Basalt-trachyte volcanoes in the Marie Byrd Land (MBL) Cenozoic province lie along the Amundsen Sea coast on the north flank of the West Antarctic rift.

Deep ductile shear localization facilitates near-orthogonal strike-slip faulting in a thin brittle lithosphere [PDF]

open access: yes, 2020
Some active fault systems comprise near-orthogonal conjugate strike-slip faults, as highlighted by the 2019 Ridgecrest and the 2012 Indian Ocean earthquake sequences.

Mechanism of Deep-focus Earthquakes Anomalous Statistics

open access: yes, 2010
Analyzing the NEIC-data we have shown that the spatial deep-focus earthquake distribution in the Earth interior over the 1993-2006 is characterized by the clearly defined periodical fine discrete structure with period L=50 km, which is solely generated ...

Effects of upper mantle heterogeneities on the lithospheric stress field and dynamic topography [PDF]

open access: yesSolid Earth, 2018
The orientation and tectonic regime of the observed crustal/lithospheric stress field contribute to our knowledge of different deformation processes occurring within the Earth's crust and lithosphere.

Mafic alkaline metasomatism in the lithosphere underneath East Serbia: evidence from the study of xenoliths and the host alkali basalts [PDF]

open access: yes, 2010
Effects of mafic alkaline metasomatism have been investigated by a combined study of the East Serbian mantle xenoliths and their host alkaline rocks.
