Oceanic anoxic events, marine photic-zone euxinia, and controversy of sea-level fluctuations during the Middle-Late Devonian
This paper reviews global records of anoxic events of the Middle Devonian–earliest
Mississippian, as well as the possible triggers and controls of these events. These “anoxic …
