Abstract: 
This study deals with the impact of early diagenesis on the distribution of trace elements in the solid phase of marine sediments. Investigations comprise detailed geochemical analyses of three 10-20 m long and undisturbed gravity cores from the equatorial and Southeast Atlantic (GeoB 1711-4, GeoB 3718-9, GeoB 4901-8). These cores were particularly suitable for the exploration of element patterns in the solid phase since pore water analyses had revealed a variety of early diagenetic environments and a large vertical extension of redox zones. Solid phase samples were taken every 5-10 cm and analysed for up to 28 elements (cf. periodic table of investigated elements, p. 116). Subsequently, a normative calculation was applied in order to split the measured total element contents up into lithogenic and excess fractions.
