On the contrary, uranium was found to be up to 3.5-fold enriched in the core section between 60 and 330 cm (within the Wuerm Glacial) where reducing conditions occur, due to deposition of authigenic uranium (9 µg/cm**2 1000 yrs.). The authigenic uranium content is correlated to the organic matter content (U/Corg ratio = 6 * 10**4). On the basis of the uranium content of the oxidized section uranium was split into a detritic and an authigenic component and the amount of supported ionium was calculated. From the profile of the specific Io-cxcess activity (= Io-total - Io-supported) with depth, average sedimentation rates of 3.3 ± 0.6 cm/1000 yrs. for the warmer stages and of 5 ± 1 cm/l000 yrs. for the cooler periods were estimated.","descriptionType":"Abstract"},{"description":"Supplement to: Mangini, Augusto (1978): Thorium and uranium isotope analyses on \"Meteor\" core 12310, NW African Continental Rise.
