New Zealand Geological Timescale 2025

New 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 ...

Evolution of the Transantarctic Basin (Southern Gondwana): Insights From Quantitative Sandstone Petrography

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The deposition of the sandstone sedimentary succession of the Beacon Supergroup lasted more than 200 Myr (Devonian to Early Jurassic) in Victoria Land and nearby territories in the so‐called Transantarctic Basin, recording crucial events in the history of the Earth.

Crustal Architecture of the Paleo‐Pacific Rift Margin of East Antarctica: Evidence From U‐Pb Ages and O‐Hf Isotope Compositions of Ross Orogen Granitoids

Geochemistry, Geophysics, Geosystems
Granitic batholiths of the ∼500 Ma Ross Orogen in Antarctica are voluminous in scale, reflecting prolific magmatism along the active early Paleozoic convergent margin of Gondwana.

Eocene Tectonic Change in the South Pacific Caused Exhumation of the Transantarctic Mountains in Northern Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Apatite fission‐track and (U‐Th)/He data indicate rapid exhumation of northern Victoria Land at 40–30 Ma, correlating with opening of Adare Trough at 43–28 Ma. Exhumation was greatest close to the Ross Sea, consistent with other regions of the Transantarctic Mountains.

The SCEC Community Rheology Model for the Southern California Lithosphere: Geological Framework, Ductile Flow Laws, and Preliminary Implications

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The Southern California Earthquake Center (SCEC) Community Rheology Model (CRM) comprises a three‐dimensional geologic framework model (GFM) of southern California's lithosphere, and synthetic aggregate ductile flow laws applicable to each GFM rock type under low‐strain conditions. Given temperature, volatile content, pressure, and strain rate,

Eocene Lamproitic Magmatism in Gangdese: Melting Sub‐Arc Lithospheric Mantle and Implications for the Early Cenozoic Magmatic “Flare Up” in Southern Tibet

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The role of sub‐arc mantle lithosphere in the build‐up of a batholith is an outstanding issue that is still not well resolved. Lamproite is a mantle‐derived magmatic rock that provides a window to learn the composition and the enrichment processes of subcontinental lithospheric mantle (SCLM).
