Autochthonous inheritance of zircon through Cretaceous partial melting of Carboniferous plutons: the Arthur River Complex, Fiordland, New Zealand

Contributions to Mineralogy and Petrology, 2010
TIMS and SHRIMP U-Pb analyses of zircons from Milford Orthogneiss metadiorite (P = 1-1.4 GPa; T ≥ 750°C) of the Arthur River Complex of northern Fiordland reveal a bimodal age pattern. Zircons are predominantly either Paleozoic (357.0 ± 4.2 Ma) and prismatic with oscillatory zoning, or Cretaceous (133.9 ± 1.8 Ma) and ovoid with sector or patchy zoning.

Thermal and Photocatalytic Conversion of CO2 to Ethanol: Advances in Catalyst Design, Challenges, and Opportunities

ChemSusChem, Volume 19, Issue 12, 26 June 2026.
This review examines thermo‐ and photocatalytic routes for converting CO2 to ethanol and analyzes how metal alloying, promoters, supports, surface structure, and semiconductor design govern catalyst activity, selectivity, and stability. It integrates mechanistic insights from experimental and theoretical studies and identifies the main challenges and ...

Zircon inheritance reveals exceptionally fast crustal magma generation processes in Central Iberia during the CambroOrdovician

, 2007
The Variscan basement of the Central Iberian Zone contains abun-dant Cambro-Ordovician calc-alkaline to peraluminous metagran-ites and metavolcanic rocks with two notable features: first, they were apparently produced with no connection to any major ...

The Role of Mafic Intrusion in Seismotectonics: Insights From the 1668 M 8.5 Tancheng Earthquake Rupture Zone Along the Tan‐Lu Fault Zone, Eastern China

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Tan‐Lu Fault Zone (TLFZ), the largest lithosphere‐scale strike‐slip fault in eastern China, has experienced multiple tectonic stages and remains high seismic activity, including the 1668 Tancheng earthquake (M 8.5). Here we employ dense‐array receiver functions to resolve crustal thickness, Vp/Vs ratio, and seismic discontinuities in the ...

1H MR‐based detection of human plasma metabolic alterations in clear cell renal cell carcinoma

BJUI Compass, Volume 7, Issue 6, June 2026.
Abstract Objectives This study aimed to evaluate the potential of plasma‐based proton magnetic resonance spectroscopy (1H‐MRS) for non‐invasive discrimination between clear cell renal cell carcinoma (ccRCC), benign renal masses (angiomyolipoma and oncocytoma) and healthy controls by identifying disease‐specific metabolic signatures.

Oligocene partial melting in the Takab metamorphic complex, NW Iran: Evidence from in situ U-Pb geochronology [PDF]

Journal of Sciences, Islamic Republic of Iran, 2013
U-Pb ages obtained on zircons from the investigated migmatites place new constraints on the evolution of the crustal rocks in the Takab area. SHRIMP U-Pb dating of inherited zircon in the melanosome parts of mafic migmatites from the Takab complex gives ...

Thermal history of the early Miocene Waitemata Basin and adjacent Waipapa Group, North Island, New Zealand

, 1999
Apatite fission track (AFT) and vitrinite reflectance (VR) data for early Miocene outcrops from the Waitemata Basin reveal that the basin sequence was subjected to shallow burial before denudation.

Loess Studies in Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...
