eucrite
Very LowTechnical/Scientific
Definition
Meaning
A type of achondritic stony meteorite, rich in calcium-poor pyroxene and plagioclase feldspar, believed to originate from the crust of the asteroid 4 Vesta.
In broader planetary science contexts, can refer to similar basaltic rocks found on other planetary bodies, though its strict definition relates to the specific Vestan meteorites.
Linguistics
Semantic Notes
A highly specific term in meteoritics and planetary geology. It denotes a specific class of meteorite with a known parent body (Vesta) and a distinct mineralogical composition (basaltic). Not to be confused with generic terms for stony or iron meteorites.

British vs American Usage
Differences
No spelling or pronunciation differences. Usage is identical in both varieties as it is a formal scientific term.
Connotations
None beyond its scientific meaning.
Frequency
Equally rare and technical in both varieties, used exclusively in specialised fields.

Examples
By Part of Speech
adjective
British English
- The eucritic composition was unmistakable.
American English
- The sample showed distinct eucritic characteristics.
Examples
By CEFR Level
- Scientists study meteorites called eucrites.
- The eucrite, a type of stony meteorite, likely comes from the asteroid Vesta.
- Petrographic analysis confirmed the specimen as a cumulate eucrite, indicating a complex igneous history within its parent body.
Learning
Memory Aids
Mnemonic
Think 'EU' as in Europe (but here from 'euc' for good/easy crystalline structure) + 'CRITE' like in meteorite. A well-crystallised meteorite from Vesta.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'eucaristia' (Eucharist) or 'evkalypt' (eucalyptus). It is a purely scientific term: 'эвкрит'.
Common Mistakes
- Misspelling as 'eucrate' or 'eukrite'.
- Using it as a general term for any meteorite.
- Mispronouncing the first syllable as 'oy' (like 'eureka') instead of 'you'.

FAQ
Frequently Asked Questions
Yes, as with all meteorites, they are rare finds, but eucrites are one of the more common types of achondritic (stony) meteorites in collections.
Yes, as a rock. It looks like a dark, fine-grained stone. Its specific identification requires laboratory analysis.
The etymology is from Greek 'eukritos', meaning 'easily distinguished', referring to its well-formed crystalline structure.
To scientists, yes, for the information they hold about the early solar system. They have modest monetary value in the collector's market, far less than rare gemstones or metals.
