文摘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 .
