TIMS Techniques for Measuring Strontium Isotope Ratios in Apatite Grains and Application to Igneous Rock Petrology

Rapid Communications in Mass Spectrometry, Volume 41, Issue 1, 15 January 2027.
ABSTRACT Rationale This study evaluates the potential of Sr isotopic compositions in apatite grains from magmatic rocks as a proxy for initial 87Sr/86Sr ratios, addressing the need for alternative approaches to conventional whole‐rock analyses in isotopic studies of granitoid systems.

Late Pliocene–Quaternary Arc Volcanism at the Southern Limit of the Hikurangi Subduction Zone: Revised Chronology of the Taranaki Peninsula, New Zealand

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 ...

Rational points on even‐dimensional Fermat cubics

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

Evolution of Summit Magma Pressure During the 2018 Caldera Collapse at Kīlauea Volcano

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract We utilized geodetic data from the 16 May to 4 August 2018 caldera collapse sequence to refine the geometries and pressure evolution of two summit reservoirs at Kīlauea volcano: the shallower Halema‘uma‘u (HMM) and deeper South Caldera (SC) reservoirs.

Permian sedimentary sequence containing analcimolite and authigenic aegirine from the Boskovice Basin (Bohemian Massif, Czechia)

The Depositional Record, Volume 12, Issue 5, November 2026.
The Permian freshwater lacustrine sedimentary sequence rich in analcime, with unusual authigenic aegirine and NaFe3+ clinopyroxene. Product of ashfall directly linked with fossil accumulation (Konzentrat‐Lagerstätte). Abstract The Early Permian freshwater lacustrine sedimentary sequence in the vicinity of Bačov (Czechia) is world‐famous for its rich ...

Peskine Sixfolds and Debarre–Voisin Fourfolds With Associated Cubic Fourfolds

Mathematische Nachrichten, Volume 299, Issue 11, Page 3367-3391, November 2026.
ABSTRACT We develop the notion of Peskine sixfolds with associated K3 surfaces and cubic fourfolds and work out numerical conditions for when these associations occur. In discriminant 24, the first family for which there is an associated cubic fourfold, we identify the cubic explicitly.

Tectonics on Early Earth Driven by Earth's Changing Shape During Tidal Recession of the Moon

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Few fragments of Earth's earliest crust have survived, and so this formative period of our planet's history is shrouded in mystery. To leverage the limited data available, it is important to understand all the processes that could have shaped our young planet.
