Etymology

Ammoniomathesiusite is named after the ammonium cation, which is a key component of its chemical structure.

How to recognize it

Ammoniomathesiusite can be identified by its yellow to greenish color and vitreous luster. It has a relatively low hardness on the Mohs scale, though the exact value is not specified. A streak test may reveal a pale coloration, and its density is moderate. Due to its rarity and unique composition, it is often confused with other uranium and vanadium-bearing minerals, but its chemical formula and crystal system help distinguish it.

Trivia

Ammoniomathesiusite is one of the few known minerals to contain the ammonium cation as a structural component. Its complex chemical formula includes both uranyl and vanadate groups, making it chemically unusual. The mineral's tetragonal crystal system adds to its distinctiveness among uranium minerals.
