- A variety of the mineral uraninite
- A brown to black mineral that has a distinctive luster. It consists mainly of urananite (UO2), but also contains radium (Ra). It is the main source of uranium (U) ore.
- The ore from which uranium and radium are obtained.
- A brown to black fine grained, amorphous, variety of uraninite which has a dull luster and contains small quantities of uranium. Also called pitch ore or nasturan.
- An important uranium ore mineral. It is black in color, possesses a characteristic greasy lustre and is highly radioactive.
