Polymetallic Manganese Nodule Deep Sea Mining Clarion-Clipperton Fracture Zone
This polymetallic manganese nodule is large and well formed. It is about 2/3 complete and has exceptional mammillations. It is from the Clarion-Clipperton Fracture Zone, the Pacific Ocean, and is well-defined with great features. Complete manganese nodules of this size are difficult to obtain, due to the turbulence of the "mining" process.

Manganese nodules are the most widespread undersea mineral resource, composed mainly of manganese minerals and are found in lumps of varying sizes.
Size: 65mm W X 50mm H X 40mm D, Weight: 100.8 grams
Rare metals and important elements have been found in manganese nodules discovered on various ocean floor systems throughout the world. The following elements have been demonstrated to be present: manganese, iron, silicon, aluminum, nickel, copper, cobalt, oxygen, hydrogen, barium, potassium, titanium, other rare earths and tellurium. The estimated age of these nodules is approximately 2.5 million years old.
Our manganese nodules were obtained in a scientific materials trade with a major university.
This polymetallic nodule arrives in a display case, Certificate of Authenticity, tag, tag stand and information about the specimen. Large acrylic base (should be available on Amazon) and photo cube is not included.
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.
Here is an opportunity to improve your scientific collection with one of the greatest geological wonders from the ocean floor.
