Sediment Characteristics in Stonewort Chara tomentosa Assemblages

Ecology and Evolution, Volume 16, Issue 1, January 2026.
The study investigated sediment characteristics associated with Chara tomentosa. The results show that sediment grain size and the concentration of the dissolved phosphate in the porewater differ in the seafloor areas characterised by C. tomentosa from adjacent areas at similar depth, but without charophytes.

Unusual biota and palynofacies of a Lower Devonian intermontane basin saline lake–playa mudflat ecosystem

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract The Strathpeffer–Struie Lower Devonian LORS (Lower Old Red Sandstone) deposits of the Northern Highlands of Scotland contain the decidedly unusual ‘foetid beds’. These are interpreted as being deposited in a highly saline sulphate lake and associated playa mudflat, which developed in an intermontane basin in the Caledonian Mountains of ...

Magmatic and Tectonic Structures in the Crust Beneath Armenia and Surrounding Regions of Lesser Caucasus Inferred From Body‐Wave Earthquake Tomography

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract The Armenian Highlands, a tectonically active segment of the Arabia‐Eurasia collision zone, exhibit widespread Quaternary volcanism, rapid uplift, and intense seismicity. However, the lithospheric processes driving these phenomena remain poorly understood.

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.
