Manganese nodule
Polymetallic nodules, also called manganese nodules, are mineral concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core. As nodules can be found in vast quantities, and contain valuable metals, deposits have been identified as a potential economic interest. [1] Manganese nodule Nodules on the seabed

The Nsuta Manganese Deposit — Ghana | SpringerLink
Abstract This relatively simple deposit illustrates the way manganese oxide Minerals can accumulate in a laterite profile. The manganese originated as a metamorphosed manganiferous sediment; quite unworkable in itself, but which has been concentrated on an old erosion surface, and which also carries ferruginous and aluminous laterites.

Manganese
As a result, most important manganese deposits occur in ancient marine sedimentary rocks that are now exposed on continents as a result of subsequent tectonic uplift and erosion. In many cases, other processes have further enriched these manganiferous sedimentary rocks to form some of today's highest grade ores.
