Sulfur and iron speciations in bottom sediments from the southwest Caspian Sea
Listed in PANGAEA
Speciations of sulfur (sulfide S, pyrite S, sulfate S) and of reactive iron (Fe3+, Fe2+, sulfide Fe) in bottom sediments have been studied in gravity cores and drill cores collected on the shelf of the southwest Caspian Sea.
Description
It has been shown that intensity of reduction processes, in particular sulfate reduction, as well as speciations of S and reactive Fe reflect the change of transgressive and regressive stages of the Caspian basin.
Characteristic features for the investigated area are high sedimentation rate and high reactivity of organic matter entering bottom sediments.
