Vertical profiles from 5 sites were analyzed using different chemical extraction methods followed by spectrophotometric geochemical analyses and organic sulfur using elemental analysis, to understand the carbon-iron-sulfur interactions during and black shale formation and upon diagenesis in the times after. completed black shale deep biosphere Demerara Rise iron content iron species ODP 207 organic sulfur sulfur content Sulfur species theme <gco:CharacterString>PANGAEA Keyword List</gco:CharacterString> 1995-01-01 creation PANGAEA

Vertical profiles from 5 sites were analyzed using different chemical extraction methods followed by spectrophotometric geochemical analyses, and organic sulfur using elemental analysis, to understand the carbon-iron-sulfur interactions during Cretaceous black shale formation and upon diagenesis in the times after.
