Abstract

The biogenic structure and biominerals in the polymetallic nodules reveal their biogenic origin. The experiment of the cation substitution capacity of synthetic 1 nm manganate suggests that chemism participates in the mineralization of the polymetallic nodules. That means the mineralization of the polymetallic nodules is two-component. After discussing the mineralization mechanism, the authors pointed out that the formation of polymetallic modules in deep-sea must meet four prerequisites: oxidative environment, very low sedimentation rate and/or hiatuses, enough nuclei, and suitable for the ultra-microbes-nodule’s builder to live.
