dedolomitize
Very low / Specialist technical termFormal, academic, technical (Geology, Petrology, Geochemistry, Soil Science)
Definition
Meaning
The geological/geochemical process of removing magnesium from a dolomite rock or mineral, converting it back into a calcite or limestone.
In extended technical usage, it can refer to any process where dolomite (CaMg(CO₃)₂) loses its magnesium component, altering its mineralogical composition and properties.
Linguistics
Semantic Notes
A highly specific term in earth sciences. It describes a reverse of the dolomitization process. It is almost exclusively used in passive/descriptive scientific contexts (e.g., 'The rock was dedolomitized').
Dialectal Variation
British vs American Usage
Differences
No significant lexical or spelling differences. Usage is identical and confined to the same technical fields.
Connotations
None beyond its strict scientific definition.
Frequency
Extremely rare in both varieties, with equal, near-zero frequency outside of specialist literature.

Examples
By Part of Speech
verb
British English
- Acidic fluids can dedolomitise the host rock over geological time.
- The section of the quarry wall appears to be partially dedolomitised.
American English
- The hydrothermal fluids dedolomitized the carbonate sequence.
- This zone has been completely dedolomitized.
adverb
British English
- The rock reacted dedolomitisingly under the experimental conditions. (Highly contrived, demonstrates formation only)
American English
- (No standard adverbial form exists or is used.)
adjective
British English
- They studied the dedolomitised limestone facies.
- The dedolomitising process was inferred from geochemical data.
American English
- The dedolomitized rock had a different porosity.
- Evidence for a dedolomitizing fluid was found.
Examples
By CEFR Level
- (Not applicable - word is far beyond A2 level.)
- (Not applicable - word is far beyond B1 level.)
- (Very unlikely, but for context): In geology, rocks can change; for example, dolomite can be 'dedolomitized' back to limestone.
- The paleokarst features are associated with dedolomitized horizons within the carbonate platform.
- Geochemical modelling suggests that meteoric water was responsible for dedolomitizing the upper section of the formation.
Learning
Memory Aids
Mnemonic
Think: DE-DOLOMITE-IZE. To take the 'dolomite' (Mg) OUT of it (DE-). The process un-does dolomitization.
Conceptual Metaphor
Process as purification or reversal (removing a component to return to a 'purer' original state – calcite).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with general terms for 'weathering' or 'dissolution' (выветривание, растворение). It is a specific type of alteration. The Russian equivalent is 'дедоломитизация' / 'дедоломитизировать', but it's equally rare.
Common Mistakes
- Misspelling: 'dedolomize', 'dedolemize'.
- Using it as an active verb for human action (e.g., 'They dedolomitized the rock' – unlikely).
- Confusing it with 'dolomitize' (its direct opposite).

FAQ
Frequently Asked Questions
No, it is an extremely rare and highly specialized technical term used almost exclusively in geology and geochemistry.
The direct opposite is 'dolomitize' (or 'dolomitise'), which is the process of converting limestone into dolomite by adding magnesium.
It would be highly unusual and likely confusing unless you were speaking with a geologist about very specific rock alterations.
In British English: /diːˈdɒləmɪtaɪz/ (dee-DOL-uh-my-tyze). In American English: /diˈdɑːləmətaɪz/ (dee-DAH-luh-muh-tyze). The stress is on the second syllable.
