Metanatroautunite
Metanatroautunite is a hydrated sodium uranyl phosphate mineral with the chemical formula Na(UO2)(PO4)·3H2O. It belongs to the autunite group of minerals and crystallizes in the monoclinic system. This mineral is typically yellow to green in color, with a vitreous to pearly luster. It has a relatively low hardness of approximately 2.5 on the Mohs scale and a specific gravity around 3.0. Metanatroautunite is radioactive due to the presence of uranium in its structure. It is classified as a nitrurite, a subgroup of the uranyl phosphate minerals, and is commonly found in uranium-rich environments.

A streak test typically reveals a white to pale yellow streak. It is often confused with other uranium-bearing minerals such as autunite and torbernite due to similar color and luster, but its distinct chemical composition and lower hardness help in differentiation.
