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.

This study investigates the impact of calcium on the performance of a large‐scale internal circulation (IC) reactor treating calcium‐rich dairy wastewater. Excessive calcium concentrations (400‐600 mg L−1) resulted in calcification of the anaerobic sludge, reactor walls, and pipes, suggesting a 17% and 25% reduction in biogas and methane production ...
