This structure produces the tabular habit, the one perfect direction of cleavage, and the relative softness. It is an analogous structure to that of the phyllosilicates . Remember, this is a radioactive mineral and should be stored away from other minerals that are affected by radioactivity and human exposure should always be limited. Colors include yellow to yellow-green. Luster is vitreous or pearly to dull.
Crystals are translucent to opaque.
Crystal Habits include tabular square crystals dominated by two pinacoid faces. Also as crusts, micaceous, foliated and earthy. Almost all meta-uranocircite crystals are pseudomorphs of uranocircite . Cleavage is perfect in one direction. Fracture is uneven.
