The Primary Redox-Reactions Degradation of Organic Matter

5 The Primary Redox-Reactions Degradation of Organic Matter 

The conceptual model for the degradation of organic matter in marine sediments was first proposed by Froelich et al. (1979). Although many more details, variations and specific pathways of these redox-reactions have become known in the meantime, this Froelich-modeF of the primary redox-reactions in marine sediments is still valid

Based on these reaetions, a snooession of different redox zones is established  

Below this zone, nitrate serves as an electron acceptor, which is a product of the redox-
