This is an exceptional, large and dense manganese nodule from the Pacific Ocean floor. It is dynamic and a complete manganese nodule. These polymetallic nodules are authigenic deposits composed principally of manganese oxides. They are enriched in Fe and Co, Ni, Cu and other elements.

They occur in all the world's oceans but are generally found in areas where the sediment accumulation rate is slow. As a result, they often form around a core material, such as a shell fragment or something else.

Size: 61mm L X 48mm W X 40mm D, Weight: 167.9 grams; Location: Clarion-Clipperton Fracture Zone, Pacific Ocean floor.

This is an absolutely premium manganese nodule for its large size! It ships with XRF analysis, tag, tag stand, and information about polymetallic manganese nodules with the Certificate of Authenticity. Acrylic display base and photo cube are not included.

This specimen was obtained directly from a scientific institution. Manganese nodules are an essential focus for possible future mining of the ocean floors.

This scientific material is Guaranteed Authentic. It was professionally and legally collected and arrives with a Certificate of Authenticity.
