英文摘要Turbidites and associated trace fossil assemblages have been extensively studied in modern and ancient sedimentary basins. However, benthic redox fluctuations induced by turbidity currents and relevant trace fossil suites (oxygen-related ichnocoenoses) have rarely been demonstrated in geological records. Here, we present an example with a well-preserved ichnocoenosis succession recording the detailed dynamic process of benthic marine oxygenation generated by turbidity currents in a Permian oxygen-deficient basin. Millimetre- to centimetre-scale sedimentological and ichnological analyses demonstrated that benthic-marine oxygenation induced by distal turbidity currents recorded in fine-grained calciturbidites from the anoxic basin began with a rapid, short-lived oxygenation event marked by the Thalassinoides/?Scolicia ichnocoenosis, followed by a relative long-term lower oxygen-level stage indicated by the ichnocoenoses of Planolites-Zoophycos and Zoophycos in turn, and ended with returning to the background anoxic benthic conditions represented by the laminated black shale. The sequential ichnocoenoses associated with turbidity current-induced oxygenation events in the Permian oxygen-deficient marine basin suggest that turbidity currents can prominently oxygenate anoxic/dysoxic bottom waters and have significant impacts on benthic communities in oxygen-deficient basins.
