Sulfur geochemistry at Sites 680 and 686 on the Peru margin

Abstract

Sulfide resulting from bacterial sulfate reduction reacts in three ways: 1) some is reoxidized to elemental sulfur in surface sediments; 2) some reacts with detrital iron minerals to form iron monosulfide and pyrite, primarily in the top meter or two of the sediment; and 3) some reacts with, and is incorporated into, kerogen. -from Authors
