Role of the Biogenic Factor in Platinum Accumulation by Oceanic Ferromanganese Nodules

摘要

A complex study of oceanic ferromanganese nodules (FMN) from the abyssal Clarion-Clipperton Fracture Zone and Lamont Guyot (Pacific Ocean) is performed. The concentrations of noble and trace elements are determined by AAS, INAA, and RFA-SR. Furthermore, SEM, and activation autoradiography are applied. Experiments are carried out using Pt, Au, and Ir radionuclides (radioisotope indicator method).
