Effects of Sulfate Reduction on Sedimentary Solid Phases

4 Effects of Sulfate Reduction on Sedimentary Solid Phases 

Sulfate reduction, occurring either dne to the oxidation of methane or the mineralization of organic material, can lead to a pronounced overprint or modification of the primary sediment composition by dissolntion/rednction of minerals and precipitation of anthigenic mineral phases. Since most of the minerals affected are also commonly used for paleoceanographic and paleo-climatologic reconstmctions it is cmcial to consider and assess the extent of diagenetic alteration of the sedimentary record driven by sulfate reduction.
