Geochemical Characteristics of Metasediment—Rich Lower Continental Crust: Insights From the Ivrea‐Verbano Zone (DIVE Drilling Project, ICDP Expedition 5071, Val d’Ossola, Italy)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 11, November 2026.
Abstract Whole‐rock geochemical data from two drill cores obtained through the ICDP (International Continental Scientific Drilling Program) funded Drilling the Ivrea‐Verbano Zone (IVZ) (DIVE) project: 5071_1_B (Ornavasso) and 5071_1_A (Megolo), provide new insights into the composition of the lower continental crust (LCC) in the IVZ. Borehole 5071_1_B (

Mesoclimatic origin affects alpine plant germination but not its plasticity

Oikos, Volume 2026, Issue 10, October 2026.
Mountain ecosystems are disproportionately exposed to global warming, which may put alpine plant species in particular at risk. Plant species' migration and persistence depend on successful seed regeneration, with demographic traits such as germination being strongly sensitive to both present and ancestral climate.

Integrated hydrologic and hydrodynamic modeling for flood hazard assessment in Ajay River Basin, West Bengal, India

River, Volume 5, Issue 3, Page 465-483, August 2026.
Abstract The Ajay River, originating from the Chotanagpur Plateau (Bihar) and flowing through Jharkhand into West Bengal before merging with the Bhagirathi‐Hugli near Katwa, is among the most flood‐prone rivers in the region. Its lower reaches frequently experience rainfall‐induced flooding and embankment breaches during the mid‐ to late‐monsoon season.

Rare-earth element geochemistry of banded iron formations and associated amphibolite from the Sargur belts, south India

, 1996
Major and rare-earth elements (REE) of banded iron formations (BIFs) and associated amphibolite from the Sargur belts, the oldest schist belts in the Dharwar craton, were determined by X-ray fluorescence and inductively coupled plasma mass spectrometry ...

A depleted mantle source for Neoproterozoic continental rifting in the Seve Nappe Complex, Kebnekaise region, northern Swedish Caledonides

Frontiers in Earth Science
The Central Iapetus Magmatic Province (CIMP) is a large igneous province (LIP) emplaced in the Baltican and Laurentian paleocontinents that marks the onset of the Caledonian Wilson Cycle.

Paleomagnetism of the Scourie Dykes, Lewisian Foreland, NW Scotland: Constraints on Early Paleoproterozoic Paleogeography of Kenorland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Scourie dyke swarm in the Lewisian foreland of northwest Scotland provides key constraints on the Paleoproterozoic evolution of the North Atlantic craton. High‐precision U‐Pb geochronology identifies two distinct intrusive phases at ∼2.41–2.38 Ga and ∼2.00 Ga.
