Ferrum-manganese nodules from the World Ocean are characterized by a complicated and polymineral composition and disseminated mineral phases. As result traditional methods of mineral diagnosis and a quantitave phase analysis are not attractive for these objects. It should be use a complex of modern analytical research methods. These methods include optical and electron microscope, X-ray spectroscopy, IR- spectroscopy, Mossbauer spectroscopy and different methods of element composition determination. In specific case these methods are complimented by a microprobe analysis and the magnetographe.
