Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, Volume 73, Issue 5, Page 1750-1798, August 2026.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

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.

Tracking Spatiotemporal Mineral Dissolution Through Quantitative Nuclear Magnetic Resonance Signatures

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Mineral dissolution reorganizes pore space through spatiotemporally variable pathways, but non‐invasive tracking remains difficult. We test whether nuclear magnetic resonance (NMR) signatures can diagnose carbonate dissolution by integrating pore‐scale reactive transport simulations with forward modeling of T2 ${T}_{2}$ distributions for face ...
