monzonite
Very LowTechnical/Scientific
Definition
Meaning
A coarse-grained igneous rock composed of approximately equal amounts of plagioclase and orthoclase feldspar, with little or no quartz.
A plutonic rock of intermediate composition, typically found in intrusive igneous bodies, used in geological mapping and petrology to indicate specific magmatic conditions.
Linguistics
Semantic Notes
A highly specific term from geology and petrology. Its meaning is precise and non-figurative, used almost exclusively to classify a rock type.

Examples
By Part of Speech
adjective
British English
- The monzonitic texture was evident under the microscope.
American English
- The monzonitic phase of the intrusion was mapped.
Examples
By CEFR Level
- Rocks can have different names, like monzonite.
- The geologist identified the grey rock as monzonite.
- The quarry exposes a large body of quartz monzonite, which is valuable for construction.
- Petrographic analysis confirmed that the pluton's core is composed primarily of biotite monzonite, indicative of a specific magmatic series.
Learning
Memory Aids
Mnemonic
Link to 'mountain zone' – monzonite is a rock often found in mountain-building zones.
Conceptual Metaphor
Not applicable. The term is purely denotative.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'монсонит' (non-standard). The established geological term in Russian is 'монцонит', a direct transliteration.
- Avoid associating with the more common word 'гранит' (granite).
Common Mistakes
- Misspelling as 'monzanite' or 'monzonate'.
- Incorrectly capitalising it as a proper noun (e.g., 'Monzonite').
- Mispronouncing the second syllable with a /zoʊ/ sound (like 'zone') instead of /zə/.

Frequently Asked Questions
Monzonite contains roughly equal amounts of plagioclase and orthoclase feldspar with little quartz, while granite is rich in quartz and alkali feldspar (orthoclase).
Monzonite is found in intrusive igneous bodies worldwide, such as batholiths, stocks, and laccoliths, often in continental crust settings.
Yes, some monzonites (especially quartz monzonite) are used as dimension stone for building and decoration, similar to granite.
Yes, as a coarse-grained (phaneritic) rock, its individual mineral crystals are typically large enough to be visible without a microscope.
