Ferrimagnetic Structure of 3C Pyrrhotite (Fe7S8) From Neutron Diffraction
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.Abstract Pyrrhotite is a paleomagnetically important magnetic mineral in many geological settings. It forms numerous polytypes with different stacking patterns of the NiAs structure along the crystallographic c axis to produce different vacancy‐ordered superstructures.

Basin Research, Volume 37, Issue 5, September–October 2025.The diagram on the left is a section view illustrating the centroid concept, whereby a permeable lithology (yellow, sand) can facilitate fluid escape from low permeability host mudstones (grey). The cartoon section on the right illustrates the location of focused fluid escape along injectites (in red) that straddles a primary overpressure zone ...

European Journal of Soil Science, Volume 76, Issue 5, September–October 2025.ABSTRACT Freshwater inland wetland systems around the world have been significantly affected by human activities, particularly disturbances (excavation) as well as drying (drought) and wetting (flooding) scenarios. These impacts often result in lowered water table levels, which can have severe environmental impacts, particularly if acid sulfate soils ...

European Journal of Soil Science, Volume 76, Issue 5, September–October 2025.ABSTRACT This paper describes models used to explain Acid Sulfate Soil (ASS) transformation processes on Norfolk Island wetlands. Prolonged drying (1970–2020) and a range of human disturbances (from cattle pugging to excavated drains) have led to lower groundwater tables and the formation of Sulfuric organic soils (pH < 4).
