Neoarchean Arc Magmatism and Crust Recycling in the Northern Marginal Zone of the Limpopo Complex, Zimbabwe: New Insights From Zircon U‐Pb‐Hf Isotopes of a Charnockite Suite

open access: yesGeological Journal, Volume 61, Issue 3, Page 566-592, March 2026.
Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

Global Comparison of Aqueous Geochemistry and Dissolved H2/CH4 in Continental Low Temperature Serpentinization–Influenced Environments

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Conceptual diagram of hydrological and geochemical processes within the Santa Elena Ophiolite, Costa Rica. It highlights watershed cross‐sections, soil genesis, hyperalkaline Type II waters (pH > 11.6) with calcite crust and trapped H2/CH4 gases, seepage into surface waters, storm‐impacted stream profiles, weathered vs.

Territorial birds of prey adjust their flight behaviour over the course of the breeding season depending on their breeding success

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Flight plays a central role in the life histories of birds but is extremely energy demanding. Reproduction is also associated with high energy demands. We might thus expect to see differences in movement behaviour between individuals that breed successfully, those that breed unsuccessfully, and those that do not breed, assuming that individuals adapt ...

New Zealand Geological Timescale 2025

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...
