摘要
The source of elements and the modem 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 -
