Our online science mall at sciencemall-usa.com is a geek gift store for the adult science enthusiast, science educator, and science researcher. Our mission is to provide science gifts, science educational products, meteorites, necklace, pendant, earrings, and fulgurite lightning sand jewelry. We also sell school geology rock and mineral specimens, rare mineral matrix specimens, pallasites, tektites, Libyan Desert Glass, fulgurite lightning sand, Lichtenberg figures, Titanic coal, school rock collections, manganese nodules, elements of the periodic table, fossils and legal historical artifacts. Rare earth rock specimens such as ancient life stromatolites (earth's earliest life), shatter cones, banded iron formation, Greenstone belt BIF banded iron formation, KT/boundary, K-Pg boundary, radioactive minerals, science art posters, prints, curio desk displays, science jewelry pendant necklace earrings, hand crafted artisan jewelry for KennedyCoJewelry, are also our specialty.
Polymetallic Manganese Nodule Deep Sea Mining Clarion-Clipperton Fracture Zone
Polymetallic Manganese Nodule Clarion-Clipperton Fracture Zone, well-defined. The picture to the left with the tag is of the back of the nodule.
Manganese nodules are the most widespread undersea mineral resource, composed mainly of manganese minerals and are found in lumps of up to about 10 centimeters in diameter.
Collection Site: Clarion-Clipperton Fracture Zone, Pacific Ocean floor
Size: 40mm H X 32mm W X 30mm D, 22 grams
Excellent mammilated specimen!
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, sodium and traces of a few others. The estimated age of these nodules is approximately 2.5 million years old. Many of the nodules that we have for sale have folds and mammilated (knobby) surfaces that are irregular to smooth in shape and size.
Our manganese nodules were obtained in a scientific materials trade with a university, in 1993. They were originally "mined" by a scientific research expedition vessel to the Pacific Ocean, in 1979, in conjunction with a major university.
This polymetallic nodule ships with a display case, Certificate of Authenticity, tag, and information about the specimen.
NOTE: Stand tag included. Cube and flat base 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 fracture zone.
Here is an opportunity to improve your scientific collection with one of the greatest geological wonders from the ocean floor.
