Augusto Mangini
The Th content of the sediment samples from "Meteor" core GIK12310-4 (3080 m water depth, off NW Africa) on a carbonate-free basis lies around the average of 12.4 ppm and is similar to the average content of the earth crust. 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...
