Legacy Seismic and Gravity Data in the Vicinity of Great Meteor Seamount and Its Tectonic Implications

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract The Great Meteor seamounts are located in the eastern Atlantic Ocean, about 750 km south of the Azores. Conjugate to the Corner seamounts in the western Atlantic Ocean, it has been suggested they formed at the same hotspot that generated the New England Seamount chain.

The Sporadic Fluvial Regime of Pliva Vallis, the Outlet Valley of Jezero Crater Lake, Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract In situ and orbital observations have suggested that Jezero crater (field site for the Mars 2020 Perseverance rover) once hosted a paleolake fed by two inlet valleys. An outlet valley, Pliva Vallis, is present on the eastern rim of the crater and raises the question of whether the lake system operated as an open basin or as a closed basin ...

A Compact, Low‐Cost Sensing System to Enable Distributed Measurements of Urban Tree Transpiration

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 5, May 2025.
Abstract Urban trees reduce air temperature and alleviate urban heat island effects through shading and transpiration, making them crucial components of climate adaptation strategies. Understanding their transpiration rates and patterns can give new insights into their response to climate stress, yet traditional sap‐flux measurements—which often ...

Heterogeneous Mantle Metasomatism Controlled by Continental Subduction: Evidence From Post‐Collisional Mafic Rocks in the North Qaidam Orogen

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract Post‐collisional mafic rocks not only record geodynamic processes at the end of the orogenic cycle but also retain various clues regarding preceding interactions between subducted slabs and mantle wedges. However, the latter and related indicators have often been overlooked; in particular, how the continental crust interacts with the mantle in

Role of Magma Ocean Differentiation in the Formation and Long‐Term Preservation of Distinct Geochemical Domains Within the Deep Mantle

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract We modeled the evolution of the terrestrial Magma Ocean using the short‐lived 182Hf‐182W isotope system (t1/2 = 8.9 Myr) in a multi‐reservoir early Earth. We start with a chondritic Earth at T0 = 4.567 Ga. Core segregates and attains its present‐day mass, W elemental and isotopic (182W/184W) composition by the end of core formation (TCF).

Equilibrium Silicon Isotope Fractionation in Eclogites and Granites Constrained by Single Crystal X‐Ray Diffraction and the Force Constants Approach

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Using our recently developed X‐ray diffraction based force constants approach, we have determined the equilibrium Si isotope fractionation between omphacite/garnet, quartz/kyanite, and quartz/zircon at temperatures relevant to the petrogenesis. We find that Na strongly affects the Si isotope fractionation between omphacite and garnet.
