Sediments i enriched in base metals (shaded) overlie basalts of ocean basin. aries and in eastern Asia and Australia, where they are separated by a gap from active conver- gent plate boundaries. Iron and ferro-alloy metal deposits have not been found along those sections of convergent plate boundaries where oceanic lithosphere is juxtaposed and island arcs are ab- sent. Sedimentary strata directly overlying basalt of the Pacific Ocean basin are enriched in iron and ferro-alloy metals, in addition to base metals. Nodules containing variable percentages of manganese, copper, nickel, and cobalt are present on about two thirds of the Pacific seafloor (Fig. 4;.
