Definition
Meaning
A greenish silicate mineral, typically found in igneous and metamorphic rocks.
Any member of a mineral group with a solid solution series between forsterite (magnesium silicate) and fayalite (iron silicate).
Linguistics
Semantic Notes
The name comes from its typical olive-green colour. The gem-quality variety is called peridot.

Context Usage
Business
Rare, except in mining, gemstone, or geological consultancy contexts.
Academic
Common in geology, petrology, planetary science, and materials science papers.

Virtually never used. If mentioned, it's in the context of gemstones (peridot) or a general interest in rocks.
Technical
Core term in mineralogy and igneous petrology for describing rock composition and formation conditions.
Examples
By Part of Speech
verb
British English
- This rock has been partially olivinised (rare technical term).
American English
- The magma began to olivinize as it cooled (rare technical term).
adverb
British English
- The rock fractured olivinically along the crystal boundaries (highly technical/rare).
adjective
British English
- The olivine-rich basalt was collected for study.
- They noted its distinctive olivine hue.
American English

- The olivine crystals were clearly visible.
Examples
By CEFR Level
- This green stone is called olivine.
- The dark rock contained small, shiny crystals of olivine.
- Geologists identified the sample as basalt due to its high olivine content.

Learning
Memory Aids
Mnemonic
Think of an OLIVE, which is green, and add 'INE' as in 'mine' or 'mineral'. Olivine is a green mineral.

Common Pitfalls
Translation Traps (for Russian speakers)
- Прямой перевод 'оливин' является точным. Ловушка: не путать с 'оливковым маслом' (olive oil).
Common Mistakes
- Misspelling as 'olivene' or 'oliviene'.
- Confusing it with serpentine, a green metamorphic mineral that can form from olivine.

FAQ
Frequently Asked Questions
Peridot is the gem-quality, transparent variety of olivine. All peridot is olivine, but not all olivine is of gem quality.
It is a major mineral in the Earth's upper mantle, a common constituent of many igneous rocks, and its composition helps scientists understand the conditions of rock formation.
It is common in basaltic lava flows, in some meteorites, and as a primary mineral in the mantle. Notable gem deposits are in places like Arizona, Myanmar, and Pakistan.
Its primary use is as the gemstone peridot. It is also studied for potential use in carbon sequestration due to its reaction with CO₂, and as a refractory sand.
