Bernasconi, S. M.; Meyers, P. A.; O'Sullivan, G. (1999): Early diagenesis in rapidly accumulating sediments on the Alboran slope, ODP Site 976. Springer International, Berlin, Germany, Geo-Marine Letters, 18 (3), 209-214, georefid:2012-014560
Abstract:
The oxidation and reduction that occur during early diagenesis of sediments has been studied in the interstitial waters of a rapidly accumulating sedimentary sequence from the Mediterranean margin of Spain. A series of reactions that are mediated by progressively lower free energy derived from oxidation of organic matter is evident in the sedimentary sequence. Iron and manganese are rapidly reduced. Phosphate and alkalinity maxima at a subbottom depth of 15 m indicate maximal organic matter degradation. Methane first appears at approximately 20 m subbottom after sulfate is depleted, and its concentrations quickly climb.
