On the seabed the abundance of nodules varies and is likely controlled by the thickness and stability of a geochemically active layer that forms at the seabed. Pelagic sediment type and seabed bathymetry (or geomorphology) likely influence the characteristics of the geochemically active layer. Nodule growth is one of the slowest of all known geologicalphenomena, on the order of a centimeter over several million years. Several processes are hypothesized to be involved in the formation of nodules, in

Polymetallic Manganese Nodule Deep Sea Mining Clarion

This manganese nodule came from the Pacific Ocean floor. It is an excellent mammilated specimen with very good characteristics and form. The estimated age of these nodules is approximately 2.5 million years old. Many of the nodules that we have for sale have folds and mammilated (knobby) surfaces that are irregular to smooth in shape and size.

Polymetallic nodules are roughly the size and shape of a potato and contain primarily manganese as well as nickel, copper, cobalt and iron. They can be found on the sea floor or buried in the sediment. Nodules can technically occur anywhere in the ocean but seem to be in greatest abundance on the abyssal planes around 5000m deep.

Polymetallic nodules are rounded accretions of manganese and iron hydroxides that cover vast areas of the seafloor, but are most abundant on abyssal plains at water depths of 4000-6500 metres.

Manganese Nodules and Cobalt-rich Crusts Cobalt Institute

Cobalt-rich crusts form at shallower depths (around 0.4 to 4 kilometres) than manganese nodules on the flanks and summits of seamounts (ISA, 2007). Accretion rates for cobalt-rich crusts and nodules are some of the slowest natural processes on the planet and can be as slow as one to six millimetres of growth every one million years.

Manganese nodules USGS

The existence of manganese (Mn) nodules (Figure 1) has been known since the late 1800s when they were collected during the Challenger expedition of 1873–1876. However, it was not until after WWII that nodules were further studied in detail for their ability to adsorb metals from seawater. Many of the early studies did not distinguish Mn nodules from Mn crusts.

Iron-Oxide Concretions and Nodules, 1 Some Meteorite

Hematite and magnetite are two iron oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron oxide concretions, iron oxide nodules, and ironstones are often mistaken for meteorites because their unusual shapes catch people’s attention and they are denser than most other rocks. Hematite concretions form by precipitation of iron oxide from iron rich solutions.
