The Buoyancy of Cratonic Lithospheric Mantle
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract Cratons are generally thought to be characterized by stable, long‐lived mantle roots. However, recent studies have suggested that the lithospheric mantle may be prone to removal, implying that it may be denser than the asthenosphere. To address these suggestions, we use a global data set of mantle xenoliths to estimate the density structure of

Toward Reconstructing Mantle Convection Using a Minimum‐Continent‐Motion Reference Frame
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.Abstract Studying geodynamic processes at the plate‐mantle interface requires knowledge of how plates move over and subduct into the mantle. The absolute motion of plates relative to the mantle since ∼120 Ma is classically estimated using hotspot tracks.

Reply to Comment by Peace et al. on “Revealing the Cape Verde Hotspot Track Across the Great Lakes”
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract In Tao et al. (2025, https://doi.org/10.1029/2024GL110777), we presented a high‐resolution seismic anisotropy model, proposing that the Cape Verde (CV) hotspot caused enhanced radial anisotropy in the North American lithosphere. We also suggested that this interaction could have created zones of low‐lying topography that set the stage for ...

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1235-1253, November 2025.This study presents the gemological analysis of 25 garnets from Hellenistic and Roman jewellery in the Archaeological Museum of Thessaloniki using mobile Raman spectroscopy and micro‐EDXRF. The garnets are classified into three geochemical clusters, with notable differences in distribution between Thessaloniki and Pydna, suggesting distinct trading ...
