The observed levels of the trace metals shows a decreasing order of abundance;

Two typical micronodules have been identified in mid Ocean ridges and environments including the diagenetic micronodules and the micronodules that are precipitated from plume fallout of oxyhydroxide matter. Whereas, with distance away from the Mid Ocean ridge segments, hydrogenous and diagenetic processes dominate due to masked hydrothermal Research/Review Article
