The Provenance of Silver in the Viking‐Age Hoard From Bedale, North Yorkshire
Archaeometry, EarlyView.ABSTRACT The acquisition of silver was a key motive propelling the Viking expansion out of Scandinavia; identifying the sources of Viking silver during the early part of the Viking Age can provide critical insights into the relative significance of western European and eastern, Islamic wealth in the Viking expansion.

Study of Galena Ore Powder Sintering and Its Microstructure
MetalsGalena is a natural mineral enriched with lead sulfide (PbS). It typically forms in hydrothermal veins associated with igneous rocks and can also occur as a gangue mineral in other ore deposits.

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment
Terra Nova, EarlyView.ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

Mineralogy of Historic Scheelite Mine Tailings at Glenorchy, Otago, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Otago Schist orogenic mineral deposits with scheelite and gold in the Glenorchy area are mineralogically and geochemically similar to, but structurally different from, those at the active Macraes gold mine in East Otago. Glenorchy veins were mined for scheelite up to 1970s, and an abandoned processing battery site at Glenorchy is now being managed for ...

Ediacara Obscura: Unveiling Hidden Magnetisations in the Fen Complex, Southern Norway
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Paleomagnetic directions found in Ediacaran (635–539 Ma) rocks are widely dispersed, which has led to conflicting hypotheses about tectonic regimes and geomagnetic field behavior during this period, and raised doubts about the fidelity of the paleomagnetic record.
