Mantle conductivity structure beneath eastern China using 3-D geomagnetic depth sounding
Frontiers in Earth ScienceThe distribution of water in the mantle plays a critical role in deep earth dynamic processes, including plate subduction, earthquake generation, and magmatic activity.

Geophysical Research LettersLow‐velocity layers (LVLs) above the 410‐km discontinuity are commonly attributed to partial melt generated by dehydration melting when hydrous mantle transition‐zone material rises into the upper mantle, where water solubility in nominally anhydrous ...

Hydrous Regions of the Mantle Transition Zone Lie Beneath Areas of Continental Intraplate Volcanism
Geochemistry, Geophysics, GeosystemsGreat volumes of water are carried downward into the mantle transition zone (MTZ, 410–670 km depth) by subducting slabs. If this water is later drawn upward, the resulting mantle melting may generate continental intraplate volcanism (IPV).

Selected Physical and Geotechnical Properties of Loess in Wairarapa Valley, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.Loess up to 10 m thick covers marine terraces, old river aggradation terraces, and gentle hill country slopes in Wairarapa, New Zealand. In the drier eastern and southern parts of Wairarapa, the loess is subject to dry summer and autumn and wet winter and spring in most years.

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.Igneous centres across the Taranaki Peninsula represent the southwestern limit of arc volcanism associated with the Tonga–Kermadec–Hikurangi subduction system. Taranaki Maunga, the youngest and largest of three andesitic stratovolcanoes, dominates the geomorphology of the Taranaki Peninsula along with the eroded remnants of the Kaitake and Pouakai ...

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.Improved satellite‐derived gravity data support updated interpretations and models of ancient plate boundaries and plate motions affecting Zealandia and West Antarctica. The models combine to confidently resolve hundreds of kilometres of Late Cretaceous–Eocene motion between the Pacific and Lord Howe plates, confirming that plate circuit constructions ...

Negative Residual Topography in Global Back‐Arc Basins Scales With Slab Dip
Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.Abstract Dynamic topography above subduction zones is widely inferred, but its magnitude and controls remain poorly constrained at the global scale. Here, we estimate residual topography across a range of back‐arc basins by correcting bathymetry for sediment loading, crustal structure, and lithospheric age, and compare the anomalies with slab geometry ...

The Depositional Record, Volume 12, Issue 5, November 2026.A succession of marine deposited scree deposits got exposed to meteoric fluids due to sea level drop or tectonic uplift. This potentially caused a unique form of diagenetic transformation in scree deposits, that is the formation of micro rhombic calcite.

Journal of Medical Virology, Volume 98, Issue 11, November 2026.ABSTRACT Most people living with HIV‐1 (HIV) are diagnosed during the chronic stage of infection, at which point viral setpoint has been established and a substantial immunopathologic damage in the secondary lymphatic tissues (LTs) has been induced. To better characterize virus‐host interaction and immunopathologic damage in LTs, we investigated viral ...
