Moctezumite

Pb(UO2)(TeO3)2
Monoclinic IMA approved

Moctezumite is a rare uranium-bearing mineral with the chemical formula lead uranyl trioxide tellurate. It belongs to the monoclinic crystal system and is classified under the Strunz system as 4.JK.65. This mineral is characterized by its yellow to yellow-green color, vitreous luster, and relatively low hardness of approximately 3.5 on the Mohs scale. It has a specific gravity of around 6.5 to 7.0, reflecting its high density due to the presence of heavy elements like lead and uranium. Moctezumite is a member of the oxide mineral group and is notable for its radioactive properties.

Etymology

Moctezumite is named after the Aztec emperor Moctezuma, in reference to its place of discovery or cultural inspiration. The mineral was officially approved by the International Mineralogical Association (IMA).

How to recognize it

Moctezumite can be identified by its yellow to yellow-green color and vitreous luster. It has a hardness of approximately 3.5 on the Mohs scale, which is relatively soft, and a high specific gravity of 6.5 to 7.0. It does not have a distinct streak. Due to its rarity and specific chemical composition, it is often confused with other uranium-bearing minerals, but its unique combination of color, luster, and density helps in differentiation.

Trivia

Moctezumite is notable for its radioactive properties due to the presence of uranium in its structure. It is a rare mineral, with only a few known occurrences worldwide. Its chemical formula includes a combination of lead, uranium, and tellurium, making it chemically unusual among oxide minerals.
