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.

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

Journal of Metamorphic Geology, Volume 44, Issue 8, Page 585-610, September 2026.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Metamorphic Reactivity Influences Amphibole Creep Behaviour

Journal of Metamorphic Geology, Volume 44, Issue 8, Page 611-632, September 2026.
ABSTRACT The rheological behaviour of solid‐solution minerals may play an important role in determining how metamorphic crust accommodates deformation. Whether or not a mineral's deformation is diffusion or dislocation‐mediated depends on a range of extrinsic variables such as stress, strain rate and temperature, as well as intrinsic variables such as ...

MAGNETITE-ILMENITE-SPINEL INTERGROWTHS IN AMPHIBOLE GABBRO OF THE SEREBRYANSKY KAMEN INTRUSION, CENTRAL URALS [PDF]

, 2022
Ontogenic analysis of magnetite-ilmenite-spinel intergrowths of ore-bearing amphibole gabbro of the Serebryansky Kamen intrusion (Central Urals) and their relationships with rock-forming silicates, apatite and Cu sulfides allowed us to reveal a number of

Direct Detection of Hydrogen Reveals a New Macroscopic Crustal Water Reservoir on Early Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The next great leap in Martian exploration is the return of samples to Earth. Maximizing their scientific value requires non‐destructive analytical techniques for early three‐dimensional characterization. Neutron computed tomography (CT), highly sensitive to hydrogen, complements conventional X‐ray CT and enables the detection of hydrous ...

Uranium mineralization in the Arya Jonoub iron oxide –apatite ore deposit

Solid Earth Sciences
The 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

Concomitant Mineral Carbonation and CO2 Reduction in Short‐Term Water‐Basalts Reaction: Difference Between Basaltic Glass and Basaltic Crystals

Global Challenges, Volume 10, Issue 8, August 2026.
Short‐term CO2–water reactions show that crystalline basalt undergoes more extensive carbonation than basaltic glass and is associated with detectable H2 and higher CO and CH4 concentrations. This contrast is consistent with the greater early reactivity of Fe‐ and Mg‐bearing crystalline phases, indicating that basalt mineralogy influences coupled ...

Emplacement Conditions and Alteration of Volcanic Deposits Inferred From Magnetic Properties of the ICDP Eger Drill Site S4 (Bažina Maar), Czechia

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Titanomagnetite in alkaline maar deposits exhibits variable syn‐ and post‐crystallization alteration linked to wet emplacement and groundwater fluctuations, which remain poorly documented. Magnetic and mineralogical analyses of lapilli, scoria, and basalt from ICDP Eger drill cores S4 and S4b (Bažina maar, western Eger Graben, Czechia) reveal ...
