| contents | A number of regularities of ore element accumulation in iron-manganese nodules along the profile from the Tsugaru Strait to the Wake Atoll is identified in the paper. It is shown that the ore process is enhanced to the pelagic zone: in nodules content of ore material increases and content of mineral insoluble residue decreases from near-shore areas to central parts of the ocean. Diagenetic redistribution of the elements between host sediments and nodules resulting to enrichment of the latter increases from bottom sediments of the ocean periphery to fine grained pelagic muds. At absolute enrichment by Fe, Mn, Cu, Ni, Co, Mo, W, Ti, Zr, and V (as compared to host sediments) nodules are relatively enriched in Mn group elements (Cu, Ni, Co, Mo, W) and consequently depleted in Fe group elements (Ti, V, Zr) in the direction from the periphery to the center of the ocean. The ratio of reactive forms of Fe and Mn in host sediments is a factor determining the ratio of Fe group and Mn group elements in nodules. |
