Accelerated Incubation Method for Identification of Boreal Soils With Hypersulfidic Material
European Journal of Soil Science, Volume 76, Issue 6, November–December 2025.ABSTRACT Sulfide‐bearing sediments (i.e., soils with hypersulfidic material) occur worldwide in many coastal and inland freshwater settings, that if exposed to oxidation, will transform to acid sulfate soils (ASS; a soil with sulfuric material) mobilizing acidity and metals into watercourses with serious environmental consequences and damage to ...

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Magnetic minerals can preserve remanent magnetization to provide ancient magnetic field records. Although thermoremanent magnetization (TRM) is well understood, chemical remanent magnetization (CRM) from chemical processes is also prevalent in nature and can complicate TRM records by introducing additional remanence signals.

Current Practices for Analyzing Soils and Sediments via Mössbauer Spectroscopy
Journal of Plant Nutrition and Soil Science, Volume 188, Issue 5, Page 742-773, October 2025.ABSTRACT Environmental scientists are increasingly returning to Mössbauer spectroscopy (MBS) to reveal details about iron (Fe)‐bearing phases in soils and sediments. MBS is particularly powerful at distinguishing between Fe(II) and Fe(III) and, given appropriate background information, can offer exceptionally precise information on Fe speciation in ...
