Geochemical Analysis of Diachronous V‐Shaped Ridges and Troughs That Flank the Reykjanes Ridge South of Iceland

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract It is recognized that mantle plumes play a direct role in generating regional uplift and producing immense volumes of basaltic magmatism, both of which can influence paleoclimate. The Icelandic Plume, beneath the North Atlantic Ocean, is of particular importance due to its size and position at a significant paleoceanographic gateway.

Overcoming Polyatomic Interferences in Sulfur Isotope Measurement Using MC‐ICP‐MS

Geostandards and Geoanalytical Research, Volume 50, Issue 1, Page 85-95, March 2026.
Key Points Optimising plasma conditions via the normalised argon index (NAI) reduces polyatomic interferences, allowing accurate sulfur isotope measurement in low‐resolution mode on MC‐ICP‐MS. Low‐resolution mode enhances sensitivity by approximately threefold compared with conventional high‐resolution analysis.

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 ...

Antarctic Intermediate Water Variability in the South Atlantic Over the Last 600,000 years

Paleoceanography and Paleoclimatology, Volume 40, Issue 12, December 2025.
Abstract Despite its importance as a key component of the Atlantic Meridional Overturning Circulation, the long‐term variability of Antarctic Intermediate Water (AAIW) remains poorly constrained due to the lack of adequate proxy records. To address this, we present the longest reconstruction of AAIW variability in the South Atlantic using authigenic ...

Confronting Episodic vs. Continuous Heat Sources in Long‐Lived Hot Orogens: Insights From Petrochronological Studies in the Nova Venecia Complex, Araçuaí Orogen (SE Brazil)

Journal of Metamorphic Geology, Volume 43, Issue 9, Page 863-890, December 2025.
ABSTRACT Orogenic belts that sustain elevated temperatures at intermediate crustal depths for tens of millions of years are known as hot orogens. The evolution of these hot orogens is largely influenced by thermal maturation, primarily driven by the distribution of heat‐producing elements (HPEs), such as K, Th and U in the overthickened crust.
