Andersonite is a hydrous sodium calcium uranyl carbonate. Axelrod et al. (1951) named the mineral after Charles Anderson (1902-1990), geologist at the U.S. Geological Survey, who collected the type material.

Andersonite forms a coating on sandstone, consisting of minute rhombohedral crystals. The rhombohedral angle is so close to 90° that crystals appear very nearly cubic.
