These profiles reveal that oxidants are consumed in order of decreasing energy production per mole of organic carbon oxidized (O2 > manganese oxides ~ nitrate > iron oxides > sulfate). Total CO2 concentrations reflect organic regeneration and calcite dissolution. Phosphate profiles are consistent with organic regeneration and with the effects of release and uptake during inorganic reactions. Nitrate profiles reflect organic regeneration and nitrate reduction, while dissolved iron and manganese profiles suggest reduction of the solid oxide phases, upward fluxes of dissolved metals and subsequent entrapment in the sediment column. Sulfate values are constant and sulfide is absent, reflecting the absence of strongly anoxic conditions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Early oxidation of organic matter in pelagic sediments of the eastern equatorial Atlantic: suboxic diagenesis","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-16 01:32:33.302183","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1979,"MonPub":null,"DateUpdate":"2015-12-14","DateCreate":"2015-12-14","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1979HD91300011","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/0016-7037(79)90095-4"},"refs":null,"anarec":{"AnaID":251921,"PubliDate":1979,"Pagination":"1075-1090","XtraPublOfAnaID":null,"ISBN":null,"Volume":"43","Issue":"7","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42901,"SerRR":"Geochimica et Cosmochimica Acta.
