Geostandards and Geoanalytical Research, Volume 50, Issue 1, Page 155-179, March 2026.Key Points Six new Ca‐Mg‐Fe carbonate reference materials are available to the global geochemical community for calibrating oxygen and carbon isotope ratios by SIMS. Significant compositional matrix effects were observed in the dolomite‐ankerite and magnesite‐siderite series during SIMS analysis. Compositional matrix effects correlate with Fe variation.

Journal of Economic Geology, 2017 Introduction Study of the petrology of the ophiolites as the relics of ancient oceanic lithosphere, is a powerful tool to reconstruct Earth’s history. Mantle peridotites have mostly undergone alteration and serpentinization to some extent.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract Fluids released from subducting hydrated rocks influence volcanism, tectonics, and geochemical cycling, but the mechanisms of fluid escape in subduction zones remain poorly understood. We address this issue by investigating the Erro‐Tobbio meta‐serpentinites (ET‐MS), Italy, exhumed serpentinite rocks that preserve extensive dehydration vein ...

Tremolite-Asbestos Presence in Roman Archaeological Site of Micia, Romania
CrystalsThis paper reports the first evidence of the presence of the mineral tremolite asbestos in Roman building materials from the Micia archaeological site (Romania), thus contributing to the understanding of the implications of ancient building materials ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract One of the main limitations in simulating subsolidus metasomatism is the decoupling between thermomechanical models and chemical/thermodynamic modeling. This decoupling amplifies the uncertainty associated with mass transport. Here, we introduce a fluid‐rock chemical‐thermomechanical interaction scheme, which integrates thermodynamic modeling (

Identifying and managing asbestiform minerals in geological collections [PDF]
, 2016 Asbestos is widely recognised as a serious hazard, and its industrial use is now banned within the UK, and EU, and strict regulations govern the use of older manufactured materials which may contain asbestos.

Interplay Between Mechanical and Petrochemical Models on the Fluid Extraction From Subduction Zones
Journal of Metamorphic Geology, Volume 44, Issue 2, Page 85-111, February 2026.ABSTRACT The breakdown of hydrous minerals during subduction results in a densification of the rocks, producing volume changes that can trigger fluid pressure fluctuations and hydrofracturing. These volume changes are controlled by the Clapeyron slope of the reaction and are quantified here using a macroscopic framework that integrates a zero ...

Critical reappraisal of Balangero chrysotile and mesothelioma risk
Epidemiology, Biostatistics and Public Health, 2022 Background Balangero, 40 km northwest of Torino in the Piedmonte Region, was home to the largest and most active chrysotile mine in Europe operating from 1916 - 1990 and employed over 300 men at any one time.

Geoscience Data Journal, Volume 13, Issue 1, January 2026.We build a new, open‐source global copper deposit dataset (GCDD), facilitating AI‐driven data analysis for exploration targeting and improving our understanding of copper mineralizing systems and their mappable expressions. The GCDD hosts information about 1483 copper deposits worldwide, capturing key deposit attributes such as location, genetic type ...
