Associate minerals include metaautunite, torbernite, phosphuranylite, saleeite, uranophane and sabugalite.
2.
Curie's systematic studies included two uranium minerals, pitchblende and torbernite ( also known as chalcolite ).
3.
It occurs associated with turquoise, chalcosiderite, cyrilovite, torbernite, libethenite, sampleite, saleeite and fluorapatite.
4.
It is especially closely associated with torbernite, but is also found amongside autunite, meta-autunite and uraninite.
5.
The chemical formula of torbernite is similar to that of autunite in which a Cu 2 + cation replaces a Ca 2 +.
6.
It is found in many minerals including uraninite ( most common uranium ore ), autunite, uranophane, torbernite, and coffinite.
7.
The number of water hydration molecules can vary between 12 and 8, giving rise to the variety of metatorbernite when torbernite spontaneously dehydrates.
8.
At other localities, francevillite is associated with duttonite, vanuralite, mottramite, carnotite, dewindtite, torbernite, uranopilite, johannite and kasolite.
9.
As torbernite is radioactive and outgases radon ( 222 Rn ), collectors are urged to take proper precautions in the handling and storage of any specimens.
10.
Uranium is found in hundreds of minerals, including uraninite ( the most common uranium ore ), carnotite, autunite, uranophane, torbernite, and coffinite.
