Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract The nature of mantle sections exhumed at magma‐poor rifted margins remains poorly constrained, largely because direct sampling of mantle in modern passive margins is exceptionally rare. The Iberia–Newfoundland system is unique in providing drilled mantle rocks on both conjugate margins, offering an unprecedented glimpse into mantle ...

Beach Gold and Heavy Mineral Concentrates on Tiwai Spit Gravel Strand Plain, Southland, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.The Holocene Tiwai Spit on Foveaux Strait is a 12 km by 2 km gravel‐dominated strand plain, ∼10 m above present sea level. Gravel clasts are dominated by well‐rounded quartz cobbles, pebbles and granules derived from Otago Schist 200 km to the north in evolving river drainage systems during late Cenozoic.

Uranium mineralization in the Arya Jonoub iron oxide –apatite ore deposit
Solid Earth SciencesThe Arya Jonoub iron oxide–apatite (IOA) deposit, located in the southern part of the Kashmar–Kerman tectono-magmatic belt, Central Iran, is hosted by Lower Cambrian volcano–sedimentary sequences intruded by diorite, gabbro, and diabase dikes. This study

Cryptic Superfine Placer Gold Populations, Round Hill Mine, Southern New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.Superfine (50–<1 µm) detrital gold and platinum group mineral (PGM) particles at the Round Hill mine near Foveaux Strait were locally derived (<20 km) from as‐yet undefined basement sources. This superfine component contrasts with the dominant coarser (typically >100 µm) gold and PGM particles at the mine that have been transported for >100 km in ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Vanadium‐bearing solid wastes (VBSWs) have emerged as a key research priority in resource recovery and environmental remediation because of their high resource value, large generation volume, and complex phase composition. However, practical utilization of these wastes still faces major challenges, including heavy environmental burdens, ill ...

The Distinction Between Sn‐Mineralized and Sn‐Barren Granites in Sn Isotopes
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Tin mineralization is commonly associated with highly evolved granites. However, not all highly evolved granitic rocks are mineralized with Sn. Comparative studies of Sn‐fertile and Sn‐barren granites can deepen our understanding of the key processes that lead to Sn enrichment in magmatic‐hydrothermal systems.
