  • Airborne volcanic ash can exert contrasting effects on redox conditions and nutrient cycling, with implications for ecosystem resilience and recovery, according to analysis of geochemical records from Late Ordovician marine and Middle Triassic lacustrine successions.

  • The loss of anomalous sulfur isotope compositions from sedimentary rocks has been considered a symptom of permanent atmospheric oxygenation. Here the authors show sulfur and oxygen isotope evidence from < 2.31 Ga sedimentary barium sulphates (barites) from the Turee Creek Basin, W. Australia, demonstrating the influence of local non-atmospheric processes on anomalous sulfur isotope signals.

  • Analysis of a series of Earth system model experiments shows that continental rearrangement during the Phanerozoic had a marked influence on variations in ocean oxygenation, independent of atmospheric pO2.

  • Nanoscale evidence suggests that the Tumbiana Formation stromatolites in Australia were influenced by microbial activity. In the stromatolites, clusters of organic globules are closely associated with 2,724-million-year-old aragonite crystals.
