Meaning and Definition
In geology, a type of rock cleavage where the alignment of minerals results from plastic flow or deformation under pressure during metamorphism.
A term in structural geology describing a penetrative planar fabric in metamorphic rocks, indicating significant strain and recrystallization where minerals have realigned parallel to the plane of shearing or flow.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Usage is identical in international geological literature.
Connotations
Neutral, purely descriptive technical term in both varieties.
Frequency
Extremely rare outside specialized geology texts or papers. Frequency is equally negligible in both UK and US general discourse.

Usage
Meaning in Context
Business
Not used.
Academic
Exclusively used in geology, petrology, and structural geology papers and textbooks to describe rock microstructures.
Everyday
Virtually never used. Would be misunderstood as a phrase related to liquids ('flow') or a split ('cleavage') in a non-technical sense.
Technical
Precise descriptor for a specific metamorphic fabric resulting from ductile deformation and dynamic recrystallization.

Common Mistakes When Using “flow cleavage”
- Using it as two separate words in a non-geological context (e.g., 'the flow cleavage of the river bank').
- Confusing it with 'rock cleavage' in general or with the everyday meaning of 'cleavage'.
- Misspelling as 'flow cleaverage' or 'flow clevage'.
FAQ
Frequently Asked Questions
No, it is an extremely specialized term used only in geology. Most native speakers will not know its meaning.
No, it is exclusively a noun phrase (a compound noun). The process is 'to develop flow cleavage'.
A planar alignment of platy or elongated minerals within a rock, formed by solid-state flow during metamorphism, often giving the rock a streaky or lined appearance.
Completely different. Diamond cleavage is about breaking along planes of atomic weakness. Geological flow cleavage is about the alignment of minerals forming a fabric within the rock, not necessarily a plane of easy breakage.
In geology, a type of rock cleavage where the alignment of minerals results from plastic flow or deformation under pressure during metamorphism.
Flow cleavage is usually technical / academic in register.
Flow cleavage: in British English it is pronounced /fləʊ ˈkliːvɪdʒ/, and in American English it is pronounced /floʊ ˈkliːvɪdʒ/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of 'flow' like taffy being stretched, and 'cleavage' like the lines that form in it. Rocks under deep earth pressure 'flow' and develop internal 'cleavage' planes.
Conceptual Metaphor
ROCK DEFORMATION IS A VISCOUS FLUID (The rock is conceptualized as a substance that can flow slowly, leaving aligned traces of its movement).
