Origin of analcime in the Neogene Arikli Tuff, Biga Peninsula, NW Turkey [PDF]

, 2012
The Arikli Tuff in the Behram Volcanics, NW Anatolia, is characterized by its dominance of authigenic analcime. It was studied by optical microscopy, XRD, SEM/EDX, and ICP for a better understanding of the analcime formation, which occurs as coarse ...

Surface Mineralogy and Hydrological Controls on “Hotspots” of Dust Emission at Etosha Pan, Namibia

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Ephemeral lake beds are globally significant sources of atmospheric mineral dust aerosols, yet emissions from these landforms exhibit considerable spatial and temporal variability. The complex interactions between climatic drivers and surface properties that govern dust emissions remain poorly understood, contributing to uncertainties in model

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 ...

The Occurrence and Morphology of Naturally Occurring Respirable Mordenite Mineral Fibres in New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Mordenite is a naturally occurring zeolite mineral that is the seventh most common zeolite mineral globally, forming at low temperatures (≥100°C) in hydrothermal systems. In New Zealand, extensive deposits of mordenite are commonly associated with areas of hydrothermal alteration, particularly in the Coromandel and Taupo Volcanic Zones.

Feasibility of Crosshole Seismic Tomography for Monitoring In Situ CO2 Mineral Storage in Basalts: A Rock Physics‐ and Seismic Modeling Study

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract In situ CO2 mineral storage is gaining increasing attention as a carbon capture and storage (CCS) technology to reduce anthropogenic CO2 emissions. So far, in situ CO2 mineral storage projects have been monitored predominantly using fluid‐ and isotope geochemical methods.

Alteration of Feldspar‐Rich Rocks on Ancient Mars and Its Possible Link to Ca/Fe‐Rich Carbonates

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Feldspar‐rich rocks have increasingly been discovered on the martian surface. They may have been an important part of the ancient martian crust and may be related to Ca/Fe‐rich carbonates (one of two types of carbonates on Mars and the other being Mg‐rich carbonates), but compared to mafic rocks, their interaction with water on ancient Mars is
