Subglacial geology and palaeo flow of Pine Island Glacier from combining glacial erratics with geophysics

Communications Earth & Environment
Subglacial geology plays a key role in determining the rate of ice flow and sensitivity of the glacial system to atmospheric or ocean warming. However, bedrock geology is often poorly known because direct information from subglacial samples is extremely ...

Geochemical characteristics of titanite and U-Pb age of garnet from mineral mines of the Southern Urals

Записки Горного института
Mineralogical-geochemical (SIMS method) study of titanite and geochronological (ID-TIMS method) study of garnets from mineral mines of the Southern Urals has been carried out. The mineral associations containing titanite belong to four contrasting types:

The Mobility of Major and Trace Elements in EOC Minerals on Parent Chondrite Bodies

Geosciences
The combined EPMA and SIMS study of the geochemical features of olivine, low-Ca pyroxene and plagioclase in equilibrated ordinary chondrites (EOCs) has revealed the effect of thermal metamorphism on trace element concentrations in EOC silicate minerals ...

Pseudorutile-leucoxene-quartz ores of Timan ‒ a new genetic type of titanium raw materials: prospects for industrial development

Georesursy
The two largest deposits of Russia – Yaregskoye and Pizhemskoye belong to the same genetic type; hydrothermal-metamorphic indigenous deposits. They are located in the same Timan structure at a distance of no more than 230 km from each other. According to

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

New 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 ...

Late Pliocene–Quaternary Arc Volcanism at the Southern Limit of the Hikurangi Subduction Zone: Revised Chronology of the Taranaki Peninsula, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Igneous centres across the Taranaki Peninsula represent the southwestern limit of arc volcanism associated with the Tonga–Kermadec–Hikurangi subduction system. Taranaki Maunga, the youngest and largest of three andesitic stratovolcanoes, dominates the geomorphology of the Taranaki Peninsula along with the eroded remnants of the Kaitake and Pouakai ...
