Abstract: | The source of elements and the modern sedimentary environment of the ferromanganese nodules enriched area of the North Pacific
region were analysed statistically and discussed in detail. Cluster analysis shows the area's surface sediments are mainly
brown clay and biogenic calcareous, calcsiliceous and siliceous ooze. Factor (principal component) analysis shows that the
area's trace elements (Fe, Mn, Cu, Co, Ni, Zn, Cr, etc.) mainly come through adsorption of clay minerals and secondarily from
authigenic sediments related to biochemical processes.
