Abstract

Abstract

The oceanic cobalt-rich crusts as same as the manganese nodules, are the latent mineral product of oceanic bottom.Studying their formation will help to lock for the mineral deposits and assessment of resources.The texture and structure, matter composition of cobalt-rich crusts and the relationships between stromatolite laminae and ultramicrobes are systematically studied by the reflection light microscope and transmission electron microscope, as well as other analysis methods.It is found that cobal-trich crusts are similar to the smooth manganese nodules in stromatolite type and ultramicrobe species: The both have minima and Miniactinomyces chinesis.They have similar organogenic mechanism.It is considered that the ultramicrobes are constructors of the basic frame of oceanic cobalt-rich crusts (manganese stromatolite columns), and thus a new view on the crust's formation is advanced.
