Rutherfordine is a mineral containing almost pure uranium carbonate (UO₂CO₃). It was discovered in 1906 and is named after Ernest Rutherford. It is found primarily in the Morogoro Region of Tanzania in Africa. It has been reported in Zaire and the Northern Territory of Australia. It appears as brownish, brownish yellow, white, light brown orange, or light yellow fluorescent encrustations. It is a secondary alteration product from uraninite. It crystallizes in the orthorhombic system in translucent lathlike, elongated, commonly radiating in fibrous masses, inpulverulent, earthy to very fine-grained dense masses. It has a specific gravity of 5.7 and exhibits two directions of cleavage. It is also known as diderichite.
