Definitions
n.noun · 名词
- 1.
- ›a mineral, hydrated copper uranium phosphate, CuU2P2O12⋅12H2O, occurring in square tabular crystals of a bright-green color: a minor ore of uranium; copper uranite.
Examples
The colour is sulphur-yellow, and this enables the mineral to be distinguished at a glance from the emerald-green torbernite.
Though closely resembling the tetragonal torbernite in form, it crystallizes in the orthorhombic system and is optically biaxial.
