Late Cenozoic Sediment Provenance in the Northern Canterbury Basin, Aotearoa New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Late Cenozoic strata of the northern Canterbury Basin record uplift and erosion of mountain ranges adjacent to the transition from oblique subduction to strike‐slip on the Australian–Pacific plate boundary. Using the provenance of conglomerate clasts and sandstone samples, we reconstruct sediment transport pathways and, by inference, exhumation and ...

Placer Gold in the Eastern Maniototo Basin, Otago, New Zealand: Deposits and Sources

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Abundant detrital gold particles in placer deposits of eastern Maniototo basin, southern South Island, New Zealand, have only minor rounding and retain many angular and crystalline features, implying derivation from a nearby source. Likewise, gold particle interior textures have undergone only minor transport‐induced deformation and recrystallisation ...

Best Practices in Open and Reproducible Antarctic Marine Sediment Core Research

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Marine sediment cores from Antarctica are archived by national programs for reuse and resampling by future researchers, creating a resourceful way to conduct Antarctic science. With reduced budgets to conduct Antarctic field work and to collect new sediment cores offshore of the icy continent, the accessibility of these archived cores and ...

Microwave‐Assisted Leaching and Mixed Oxalates Precipitation as Closed‐Loop NMC532 Recycling Process

open access: yesChemElectroChem, Volume 13, Issue 21, 3 November 2026.
This work presents a microwave‐assisted hydrometallurgical organic‐acid‐based recycling process for NMC cathode using mixed oxalates as precursors, that results in being straightforward and effective. Selected mixed‐metals oxalates are used to close the recycling loop and recover NMC532 crystalline structure through a solid‐state relithiation procedure,

Compressive Creep of Fireclay Refractories With Varying Recycled Content

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 8, Issue 6, November 2026.
Compressive creep of fireclay bricks with varying recycled fractions was studied up to 1100°C using the Norton–Bailey law. Higher recyclate contents reduced creep strain and rates. Although bulk chemistry is similar, microstructures differ: Recyclate fines generate more liquid, accelerate transformations, erase texture, and therefore lower creep rates.
