Solid-state mantle convection coupled with a crystallising basal magma ocean

Comptes Rendus. Géoscience
Fractional crystallisation of a basal magma ocean (BMO) has been proposed to explain the formation of large scale compositional variations in the mantle and the persistence of partially molten patches in the lowermost mantle. We present a complete set of

On the impact of true polar wander on heat flux patterns at the core–mantle boundary [PDF]

Solid Earth
The heat flux across the core–mantle boundary (CMB) is a fundamental variable for Earth evolution and internal dynamics. Seismic tomography provides access to seismic heterogeneities in the lower mantle, which can be related to present-day thermal ...

Fluorinated and B‐Vinylated Tris(pyridyl)borate in Copper(I) Coordination Chemistry

European Journal of Inorganic Chemistry, EarlyView.
Coordinatively flexible tris(pyridyl)borate stabilizes copper coordination complexes, including those with ethylene and carbon monoxide. Fluorinated tris(pyridyl)borate with a vinyl substituent on boron was synthesized and comprehensively characterized, expanding the diversity and functional versatility of the poly(pyridyl)borate ligand family.

Surface Consistent Seismic Hazard Assessment in the Shillong Plateau, Northeast India: A Probabilistic Approach Using Multiple Source Models and a Logic Tree Framework

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.

A Tilted Broad Plume Underneath the Greenland Cratonic Keels

Geophysical Research Letters
To advance our comprehension of the complex geological history and mantle dynamics in the North Atlantic region, we employ all available broadband seismic data recorded in Greenland to reveal an abnormal mantle transition zone (MTZ) structure.

Dissociation of salts in water under pressure

Nature Communications, 2020
Salts in water at extreme conditions play a fundamental role in determining the properties of the Earthʼs mantle constituents. Here the authors shed light on ion-water and ion-ion interactions for NaCl dissolved in water at conditions relevant to the ...

Plant‐Derived Extracts Disrupt Biofilm Formation and Quorum Sensing in Yersinia enterocolitica: Insights From GC‐MS and Molecular Docking

Food Chemistry International, EarlyView.
The graphical abstract represents how natural plant products that preferentially target the specific receptors of quorum sensing could be developed to combat biofilms linked to Yersinia enterocolitica using the potent abilities of protein–ligand complexes with high docking scores.

Stagnant forearc mantle wedge inferred from mapping of shear-wave anisotropy using S-net seafloor seismometers

Nature Communications, 2020
Knowledge of shear-wave anisotropy is important to understanding the structure and dynamics of the subduction zone mantle wedge. Here, the authors find unambiguous evidence that forearc anisotropy resides in the upper-plate crust, while weak anisotropy ...

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

Geological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Receiver Function Imaging of the Mantle Transition Zone Beneath the East Sayan Mountains and Adjacent Area in Central Asia: Implications for Lithospheric Drip and Intraplate Cenozoic Volcanism

Geophysical Research Letters
To provide constraints on the formation mechanisms of intracontinental volcanisms and intriguing lithospheric thickness variations in the East Sayan Mountains and surrounding areas, we stack P‐to‐s receiver functions to image the 410‐km and 660‐km ...
