Progress in mantle anisotropy research based on XKS phases

地球与行星物理论评
XKS shear-wave splitting has been widely applied to investigations of anisotropy in both the upper mantle and the lowermost mantle D" layer, and represents a key tool for probing mantle deformation and dynamics.

Seismotomography of the mantle under the East European platform: mantle velocity boundaries

Геофизический журнал, 2012
Mantle velocity boundaries of EEP have been specified. For the upper mantle and its tranzi-tion zone dynamics of propagation of mantle velocity limits with depth has been presented.

Inference of the Timescale‐Dependent Apparent Viscosity Structure in the Upper Mantle Beneath Greenland

AGU Advances, 2023
Contemporary crustal uplift and relative sea level (RSL) change in Greenland is caused by the response of the solid Earth to ongoing and historical ice mass change.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

ScS shear-wave splitting in the lowermost mantle: Practical challenges and new global measurements

Seismica
Many regions of the Earth's mantle are seismically anisotropic, including portions of the lowermost mantle, which may indicate deformation due to convective flow.

Noble gases confirm plume-related mantle degassing beneath Southern Africa

Nature Communications, 2019
Southern Africa is characterised by unusually elevated topography and abnormal heat flow. This can be explained by thermal perturbation of the mantle, but the origin of this is unclear.

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Subduction Dynamics and Mantle Pressure: 2. Towards a Global Understanding of Slab Dip and Upper Mantle Circulation

Geochemistry, Geophysics, Geosystems, 2020
We investigate the relationship between the global distribution of deep slab dips (at 250‐ to 300‐km depth) and pressure and circulation in the upper mantle.

Coherence‐Gated Wrapped‐Phase InSAR With Matrix‐Based Uncertainty Diagnostics for Burial‐Mound Hotspot Ranking (Sicily, Italy)

Archaeological Prospection, EarlyView.
ABSTRACT Burial mounds are key elements of Mediterranean funerary landscapes, but in intensively cultivated coastal plains their low‐relief expression is easily obscured by ploughing, levelling and rapidly changing surface conditions, making single‐date observations unreliable.

Integrated Clinical and Proteomic Profiling of CD19 Chimeric Antigen Receptor T Cell Therapy in Progressive Systemic Sclerosis

Arthritis &Rheumatology, EarlyView.
Objective To characterize the clinical, immunologic, and proteomic changes associated with CD19 chimeric antigen receptor T cell therapy in patients with progressive systemic sclerosis (SSc). Methods Patients with progressive SSc received CD19 chimeric antigen receptor (CAR)‐T cell therapy and were observed longitudinally for safety, clinical efficacy,
