These are ion microprobe analyses of oxygen isotope ratios, grey scale values from confocal laser fluorescence images, and distance perpendicular to banding for analyses that were shown to be regular
A high-resolution study including oxygen and carbon stable isotopes as well as carbonate and total organic carbon contents, has been performed on undisturbed near-surface (0-40 cm) sediment sequences
Geochemical studies of single mineral grains in rocks can be probed to reconstruct the history of our planet. The mineral zircon (ZrSiO4) is of unique importance in that respect because of its reliabi
230Thxs corrected for decay and assuming a 238U/232Th ratio of R=0.5, sediment focussing factors assuming dry bulk density of 0.5g/cm**3, and 230Th normalized sediment fluxes.
