natrolite
C2Academic/Technical
Definition
Meaning
A fibrous mineral, a type of zeolite, consisting of hydrous sodium aluminum silicate.
A relatively rare tectosilicate mineral found in cavities in basaltic rocks, often appearing as acicular or needle-like crystals, and used in mineralogy and geology for classification and study.
Linguistics
Semantic Notes
Natrolite is a specific mineral species. The term is used almost exclusively within geology, mineralogy, and related scientific fields. There is no figurative or everyday usage.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)

Common Mistakes
- Misspelling as 'natralite' or 'natrolight'.
- Using it as a general term for any white, fibrous mineral.

FAQ
Frequently Asked Questions
No, natrolite is a mineralogical specimen, not a gemstone. It is valued by collectors and for scientific study, but it lacks the durability, clarity, and rarity for use in jewellery.
Natrolite is typically found in cavities within basaltic and other volcanic rocks. Notable locations include parts of Canada, Russia, Germany, and the United States (e.g., New Jersey).
The name derives from the Greek 'natron' (soda, referring to its sodium content) and 'lithos' (stone), literally meaning 'soda stone'.
It would be highly unusual and context-specific. The word is almost exclusively used by geologists, mineralogists, and rock collectors.
