Low Hazard–High Risk: A Case Study of the Active Mangatangi Fault

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Activity on low deformation rate faults are challenging to quantify and comparatively understudied. One such fault, the Mangatangi Fault, strikes NE‐SW along the southeastern flanks of the Hunua Ranges c. 52 km south of New Zealand's most populous city, Auckland.

A Machine‐Learning Classification for Torlesse Composite Terrane Petrofacies and its Application to Sediment Provenance

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The Torlesse Composite Terrane (TCT) forms many of the mountain ranges in Aotearoa New Zealand and has provided enormous quantities of coarse‐grained sediment to Te Riu‐a‐Maui/Zealandia's basins since the mid‐Cretaceous. Tracing the provenance of these sediments to certain regions of the TCT can indirectly reconstruct exhumation patterns associated ...

Two Germans, a Swede, and a Giant kōkopu: The Background to the Earliest Documented Description of a New Zealand Freshwater Fish

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
Galaxiids are a family of scaleless and mostly small freshwater fish which are distributed across the temperate latitudes of the southern hemisphere. The largest member of this family is the giant kōkopu (Galaxias argenteus), which has the added distinction of being the first New Zealand freshwater fish of any kind to be scientifically described.

Iron Fertilization of the North Pacific Did Not Drive Long‐Term Pliocene to Quaternary Cooling

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract While several hypotheses exist to explain the development of large‐scale perennial Northern Hemisphere ice sheets in the late Pliocene and early Pleistocene, the prevailing view is that a decline in atmospheric carbon dioxide (CO2) drove this substantial change in late Neogene climate.

New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Eastward Growth of the Tibetan Plateau Linked to Cenozoic Orogenic Wedge Deformation and Fluctuating Melt Sources

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The India–Asia collision continuously loads the Tibetan Plateau (TP), driving its Cenozoic eastward growth. This process has caused extensive crustal deformation and a diverse magmatic response. Here, we report on newly identified 35−6.5 Ma granitoids from Kangding area in southeastern (SE) TP.
