Abstract:

Phosphorite nodules collected during Cruise 8 of R/V Dmitry Mendeleev off the Peruvian coast are represented by three lithologic types: friable, compacted, and solid. As the nodules are progressively compacted, contents of phosphate components increase and of non-phosphate components decrease. Isotope composition of uranium in the friable nodules is the same as in ocean water, and diatoms contained in the nodules are represented by recent species indicating Late Quaternary age of the nodules.
