Intermittently Bubbling Well With He‐Rich N2‐Bubbles Constrain the Possibility of Atmospheric and Biogenic N2 Exsolution and the History of He‐Rich Groundwater From Basement to Surface

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Using Henry's law for di‐nitrogen and simple budget equations, we show theoretically that generating N2 ${\mathrm{N}}_{2}$ bubbles in spring water, by exsolution of atmospheric N2 ${\mathrm{N}}_{2}$ formerly dissolved in recharge water, is possible if the water becomes warm and salty at depth in the basement before rising upward when pressure ...

Chromite in main group pallasite meteorites: Accessory mineral tracing planetesimal differentiation

Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2703-2714, November 2025.
Abstract Main group pallasite meteorites (PMG) are samples of an early, highly differentiated magmatic planetesimal dominated by olivine and metal‐sulfide‐phosphide assemblages with accessory chromite among other phases. This mineralogy reflects mantle‐ and core‐related reservoirs, but the relative contributions of each and the overall petrogenesis are

Asteroseismology And Galactic Archaeology

, 2018
The Milky Way is a complex system, with dynamical and chemical substructures, where several competing processes such as mergers, secular evolution, gas accretion and gas take place. To study how such a giant spiral galaxy was formed and evolved, we need to reconstruct the sequence of its main formation events with high temporal resolution ...

‘CELTIC BRITAIN’ IN PRE‐ROMAN ARCHAEOLOGY, RECONSIDERED

Oxford Journal of Archaeology, Volume 44, Issue 4, Page 446-461, November 2025.
Summary For forty years archaeologists have avoided referring to pre‐Roman Britain and its inhabitants as ‘Celtic’ on the grounds that contemporaries never described them as such. This is incorrect. The second‐century BC astronomer Hipparchus quotes Pytheas (c. 320 BC) as having referred to Britons as ‘Keltoi’.

[X/Fe] Marks the Spot: Mapping Chemical Azimuthal Variations in the Galactic Disk with APOGEE

The Astrophysical Journal
Chemical cartography of the Galactic disk provides insights into its structure and assembly history over cosmic time. In this work, we use chemical cartography to explore chemical gradients and azimuthal substructure in the Milky Way disk with giant ...

A Multifaceted Spatial Analysis of Tomb Distribution in Blemmyan Berenike (Eastern Desert of Egypt)

Archaeological Prospection, Volume 32, Issue 4, Page 777-795, October/December 2025.
ABSTRACT This study examines the spatial and visual organisation of tombs in the post–Roman Berenike located in Egypt's Eastern Desert. Archaeological surveys, remote sensing, geophysical methods, excavations and GIS‐based analyses are used for a comprehensive understanding of the spatial patterns and cultural significance behind the positions and ...
