Growth of a polymetallic nodule from the northwestern continental margin of the South China Sea and its response to changes in the paleoceanographical environment of the Late Cenozoic
In the northern South China Sea, the accumulation of enormous quantities of terrigenous sediment during Cenozoic rendered well-developed polymetallic nodules very rare. In this study, we analyzed a polymetalli...
