Zusammenfassung
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.
