In sedimentology and geology, a nodule is a small, irregularly rounded knot, mass, or lump of a mineral or mineral aggregate that typically has a contrasting composition, such as a pyrite nodule in coal, a chert nodule in limestone, or a phosphorite nodule in marine shale, from the enclosing sediment or sedimentary rock.normally, a nodule has a warty or knobby surface and exists as a discrete.

Manganese nodules an additional potential source of manganese is the ferromanganese nodules and crusts that occur on the seafloor in many parts of the world's oceans. 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. The nodules form by precipitation from lake and ground water in areas where the influx of other sediment is low.

The lake michigan nodules, with up to 22% manganese, were first found in five localities within green bay and another in lake michigan off the coast of kewaunee county (rossman and callender, 1968). The cook islands (cis) exclusive economic zone (eez) encompasses 1,977,000 km2 and includes the penrhyn and samoa basins abyssal plains where manganese nodules flourish due to the availability of prolific nucleus material, slow sedimentation rates, and strong bottom currents. Mining of manganese nodules has been… Manganese nodules 7 the geology of manganese nodules james r. Formed in oceans as a result of pelagic sedimentation or precipitation. Thus, technically speaking, they are concretions instead of nodules. Under very slow conditions of i deposition, as occur on the bottoms of the oceans, manganese precipitates as a colloid which picks up cobalt ions present in solution.
