Evolution Model for the Paleoproterozoic Talvivaara Mudstone‐Hosted Ni‐Zn‐Cu‐Co Deposit in Fennoscandia

Terra Nova, Volume 38, Issue 4, Page 221-232, August 2026.
ABSTRACT The Paleoproterozoic Talvivaara mudstone is a very large sulfidic Ni‐Co deposit that records enhanced organic matter accumulation during the global Shunga Event. Here, rock geochemistry and microscale S and Fe isotope composition of in situ pyrrhotites and pyrites are studied in well‐characterised, well‐preserved drill core samples.

Electrical Conductivity of Hydrous Ultramafic Melts With Implications for Origin of Low Velocity Layer Atop of the 410 km Seismic Discontinuity

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Low‐velocity layers (LVLs) above the 410‐km discontinuity are commonly attributed to partial melt generated by dehydration melting when hydrous mantle transition‐zone material rises into the upper mantle, where water solubility in nominally anhydrous minerals decreases.
