    Class : Carbonates, Nitrates, Borates
    Subclass : Uranyl carbonates
    Crystal System : Trigonal
    Chemistry : Na₂Ca(UO₂)(CO₃)₃ 6H₂O
    Rarity : Rare

Andersonite is a green-yellow secondary uranium carbonate which crystallizes in the oxidation zone of uranium deposits, associated with other secondary minerals of this metal (liebigite, carnotite, etc...). It was named in honor of Charles Alfred Anderson, a member of the U.S. Geological Survey, who discovered it. It is a mineral which forms small rhombohedral crystals of 1 cm at most, sometimes pseudocubic, as well as thick encrustations. This mineral has no particular use.
