Pb-Zn and minor U mineralization at Tyndrum, Scotland. [PDF]

, 1985
This mineralization occurs as veins and vein breccias in fractures associated with the Tyndrum-Glen Fyne fault. Quartz, galena and sphalerite, with minor chalcopyrite and baryte, are accompanied by small inclusions (in the galena-rich veins) of ...

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.

Microbially Mediated Intracellular Barite Mineralization: Evidence From an Early Ediacaran Microfossil in the Doushantuo Formation of South China

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Barite serves as a key proxy for reconstructing paleo‐oceanic productivity and chemistry in modern and ancient marine sediments. Although contemporary barite precipitation involves biological mediation, the mechanisms responsible for ancient barite formation remain unclear.
