Sediment cores with different sub-bottom depths (I: 45 cm and II: 700
cm) from the Peru Basin have been investigated. From the depth profile
of the relative amount of Fe(II) a redox zone is obtained which corre
lates with the organic carbon flux into the sediment (core I). Mossbau
er parameters suggest that the iron in the sediments is mainly contain
ed in clay minerals and to varying extent also in goethite.
