Nearshore euxinia in the photic zone of an ancient sea

Evidence for photic zone euxinia (PZE) in ancient oceans is widespread and commonly associated with global climate change and biotic events. However, evidence of PZE in marginal settings is commonly extrapolated to infer basin-scale characteristics. To explore the relationship between euxinia in marginal settings and the wider basin in one Palaeozoic context, we have conducted a detailed spatial and temporal examination the palaeowater-column...
