scolecite
Very rareTechnical/scientific
Definition
Meaning
A white, fibrous mineral consisting of hydrated calcium aluminosilicate, belonging to the zeolite group.
In geology and mineralogy, a needle-like or acicular crystal often found in cavities in volcanic rocks; a collector's mineral prized for its delicate, radiating crystal formations.
Linguistics
Semantic Notes
The term is exclusively used in mineralogy and geology. It is a hypernym within the zeolite mineral group. There is no everyday metaphorical use. The name derives from the Greek for 'worm', referring to its tendency to curl when heated.

- The geologist identified the fibrous crystals as scolecite.
- Scolecite is often found alongside other zeolites in volcanic cavities.
- The prize of the collection was a superb spray of radiating scolecite crystals on a matrix of prehnite.
- Chemical analysis confirmed the specimen was scolecite, not a similar fibrous zeolite like natrolite.

Mnemonic
SCOLEcite CURLS like a worm when heated (from Greek 'skōlēx' = worm).
Conceptual Metaphor
Not applicable; the term is a literal, technical label with no common metaphorical extensions.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'skolioz' (сколиоз - scoliosis).
- The Russian equivalent is 'сколецит' (skoletsit), a direct transliteration.
Common Mistakes
- Misspelling as 'scolocite' or 'scolensite'.
- Mispronouncing the first syllable as /skoʊl/ (like 'school') instead of /skɒl/ or /skɑːl/.
- Assuming it has a general English meaning.

FAQ
Frequently Asked Questions
Scolecite is a fibrous, white mineral belonging to the zeolite family, composed of hydrated calcium aluminosilicate.
It is typically found in cavities within basaltic and other volcanic rocks. Notable localities include India, Iceland, and New Jersey, USA.
It has no significant industrial value but is highly valued by mineral collectors for its aesthetic crystal formations, especially fine specimens from places like Pune, India.
Distinguishing it from similar fibrous zeolites like natrolite or mesolite often requires tests for crystal habit, reaction to acid, or advanced techniques like X-ray diffraction.
