Dynamic Polymetallic Manganese Nodule 105 grams XL

This is an excellent polymetallic manganese nodule that is very dynamic, large, and well-formed. It has exceptional mammillations, and the back reveals the dynamics of its internal structure. Manganese nodules of this size have a difficult time staying intact 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: 70mm H X 58mm W X 45mm D, Weight: 105 grams

Rare metals and important elements have been discovered in manganese nodules on various ocean floor systems worldwide. The following elements are present: manganese, iron, silicon, aluminum, nickel, copper, cobalt, oxygen, hydrogen, barium, potassium, titanium, other rare earth, 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 ships with a Certificate of Authenticity, tag, tag stand, and information about the specimen. Large acrylic stand and photo cube are 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 from the Clarion-Clipperton fracture zone.

Here is an opportunity to add a significant specimen to your geological collection!
