tungstite
Very LowTechnical/Scientific
Definition
Meaning
A yellow mineral consisting of tungsten trioxide (WO₃).
A secondary mineral formed by the oxidation of tungsten-bearing ores, typically found in the oxidized zones of tungsten deposits.
Linguistics
Semantic Notes
The term is used almost exclusively in geology, mineralogy, and mining contexts. It refers specifically to the mineral form of tungsten trioxide, not to the element tungsten or its other compounds.

Learning
Memory Aids
Mnemonic
Think: TUNGSTen + -ITE (a common suffix for minerals) = TUNGSTITE, the mineral form of tungsten.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'вольфрамит' (wolframite), which is a different tungsten ore.
- The '-ite' ending reliably indicates it is a mineral name.
Common Mistakes
- Using 'tungstite' to refer to the metallic element tungsten (correct: 'tungsten').
- Misspelling as 'tungstenite' (which is a different mineral, tungsten disulfide).

FAQ
Frequently Asked Questions
No, tungstite is a relatively rare secondary mineral.
It is not a primary ore, but as a tungsten trioxide mineral, it contains tungsten and could be a source under specific circumstances.
Tungstite is typically yellow, yellow-green, or yellowish-brown.
It is found in the oxidized zones of tungsten-bearing deposits, often forming as an alteration product of primary tungsten ores like wolframite.
