Zircon. The mineral zircon (zirconium silicate) generally occurs in nature as a crystal. Most of the naturally occurring radioactive material (NORM) found in zircon is uranium and thorium, which is created during the crystallization of the mineral from the molten host rock when it is initially formed.
