Polymetallic Manganese Nodules - 5 lbs bag Pacific Ocean Floor; Size from 1/4" to over an inch, various sizes.
The following elements have been demonstrated to be present: manganese, iron, silicon, aluminum, nickel, copper, cobalt, oxygen, hydrogen, barium, potassium, and titanium.
The estimated age of these nodules is approximately 2.5 million years old.
Location: Clarion-Clipperton Fracture Zone, Pacific Ocean;
The nodules can have folds and mammilated (knobby) surfaces that are irregular to smooth in shape and size. The manganese nodules were obtained in a scientific materials trade with a university, in 1993. They were originally "mined" from a scientific expedition to the Pacific Ocean, in 1979, in conjunction with a major university.
About 200-400 pieces per bag. Durably double bagged.
The bag in the picture of these nodules is 12" W X 19" L.
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 fracture zone.
Here is an opportunity to improve your scientific collection with one of the greatest geological wonders from the ocean floor.
Also ships with Certificate of Authenticity and information. Ruler not included.
