As a consequence, this environment is completely anoxic and, due to the activity of sulfate reducers, contains sulphide at a concentration of 2.9 mM. Source: Internet
Hydrogen sulfide emissions A severe anoxic event at the end of the Permian would have allowed sulfate-reducing bacteria to thrive, causing the production of large amounts of hydrogen sulfide in the anoxic ocean. Source: Internet
Black shales which form in anoxic conditions contain reduced free carbon along with ferrous iron (Fe 2+ ) and sulfur (S 2− ). Source: Internet
Hydrochemistry Because of the anoxic water at depth, organic matter, including anthropogenic artifacts such as boat hulls, are well preserved. Source: Internet
In many places around the world, dark anoxic shales were formed during this interval. Source: Internet
