nickel bloom
Very LowTechnical (Geology, Mineralogy, Chemistry)
Definition
Meaning
A hydrated nickel arsenate mineral, forming earthy, green, or pale blue crusts or coatings.
A term in mineralogy for the naturally occurring, weathered, or altered form of nickel arsenate, often found in oxidation zones of nickel ore deposits. Its characteristic appearance gives it the 'bloom' name.
Linguistics
Semantic Notes
This is a specialized compound noun naming a specific mineral. 'Bloom' here refers to a fine, powdery coating, analogous to 'flower' (a direct translation of the German 'Blüte') used in mineral names like 'iron bloom'.

Examples
By Part of Speech
verb
British English
- The ore body began to nickel-bloom after prolonged exposure.
American English
- The tailings are starting to nickel-bloom, indicating oxidation.
adjective
British English
- The nickel-bloom encrustation was carefully sampled.
American English
- They noted a nickel-bloom coating on the specimen.
Examples
By CEFR Level
- The green powder on the rock might be a mineral.
- Geologists identified a green coating on the mine walls as a nickel mineral.
- The presence of nickel bloom, a secondary arsenate mineral, is a key indicator of the oxidation zone in this deposit.
Learning
Memory Aids
Mnemonic
Picture a NICKEL coin left outside that gets a green, mouldy BLOOM on it. Nickel bloom is a green, crusty bloom on nickel-rich rocks.
Conceptual Metaphor
MINERAL COATINGS ARE BLOSSOMS / FLOWERS (as in 'flower of zinc' for zinc oxide).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'bloom' as цветение (blossoming). It is a technical term for налет, выцвет.
- Ensure the correct technical mineral name is аннабергит (annabergite).
Common Mistakes
- Confusing it with 'nickel blossom', an incorrect direct translation.
- Using it as a general term for any nickel corrosion.
- Capitalising it as a proper name (it is not).

FAQ
Frequently Asked Questions
No, it is an extremely specialized term used only in geology, mineralogy, and related fields.
In mineralogy, 'bloom' refers to a fine, powdery, often brightly coloured coating on a rock or mineral surface, resembling a dusting of powder.
Essentially, yes. 'Annabergite' is the more formal and specific mineral name, while 'nickel bloom' is a descriptive name referencing its composition and appearance.
It would be highly unusual and likely confusing unless you were specifically discussing mineral specimens with an expert.
