They include: manganese, iron, silicon, aluminum, nickel, copper, cobalt, oxygen, hydrogen, barium, potassium, titanium, rare earth, tellurium, and more. The estimated age of these nodules is about 3 million years old.

Our manganese nodules were obtained in a scientific materials trade with a major university.

A professional XRF elemental assay metallurgical laboratory printout analysis is included with this order. The XRF analysis is consistent with other manganese nodules coming from this region.

A great addition to any scientific collection!
