Geoelectrical Classification of Gypsum Rocks

Surveys in Geophysics, 2010
Abstract Gypsum rocks are widely exploited in the world as industrial minerals. The purity of the gypsum rocks (percentage in gypsum mineral in the whole rock) is a critical factor to evaluate the potential exploitability of a gypsum deposit. It is considered than purities higher than 80% in gypsum are required to be economically profitable.

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

Boreas, EarlyView.
Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

The Geomagnetic Storm on 10–12 May 2024 and Its Effect on the Swedish Power Grid

Space Weather, Volume 24, Issue 2, February 2026.
Abstract On 10–12 May 2024, at least five interplanetary coronal mass ejections (ICMEs) arrived at Earth and caused the strongest geomagnetic storm in over 20 years. During this geomagnetic storm, a disturbance occurred in a transformer in southern Sweden, causing a drop in power supply in the power line connecting Sweden and Poland.

Low‐Frequency Polarization of Blank Ice Features in Solid Rocks

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract For hydrogeological management of seasonally frozen soils, or permafrost, the quantification of ice and water content is key. Changes in electrical conductivity are commonly used to monitor ice‐to‐water ratios but hard rocks, ice and air are all highly resistive materials.

Capturing soil moisture and salinity changes in flooded coastal forests using electrical resistivity and induced polarization

Vadose Zone Journal, Volume 25, Issue 1, January/February 2026.
Abstract Geophysical methods provide high‐resolution spatial measurements of physical quantities sensitive to changes in soil moisture and salinity and can be used to monitor soil hydrological responses to flooding. However, extracting quantitative hydrological information from geophysical data remains challenging.

Regional Three‐Dimensional Magnetotelluric Electrical Resistivity Model of the Manica Greenstone Belt, Western Mozambique

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Magnetotelluric (MT) survey results from the Late Archean Manica greenstone belt, an extension of the Odzi‐Mutare greenstone belt of the Zimbabwe Craton, are presented. A total of 33 MT stations were acquired on an irregular grid with an average station spacing of approximately 5 km.
