samarskite
Very lowTechnical/Scientific
Definition
Meaning
A black or brownish-black mineral that is a source of rare-earth elements, thorium, uranium, and other metals.
In geology and mineralogy, a complex, radioactive oxide mineral found in granite pegmatites. Its discovery was historically significant in the identification of the element samarium.

Examples
By CEFR Level
- Samarskite is an important source of rare-earth metals.
- The geologist identified the black crystal as samarskite.
- Detailed analysis of the pegmatite revealed significant quantities of samarskite intergrown with fergusonite.
- Due to its radioactive nature, samples of samarskite must be handled with appropriate safety precautions.
Learning
Memory Aids
Mnemonic
SAMARskite contains SAMARIum; the mineral is named after the element it helped discover (Samarium, itself named after the mining official Vassili Samarsky-Bykhovets).

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with the city 'Samara' or the name 'Samarsky'.
- The '-ite' ending indicates a mineral, not a person or place in this context.
- It is a highly specific term with no common Russian equivalent; transliteration (самарскит) is used.
Common Mistakes
- Misspelling as 'samarskate', 'samarsite', or 'samarskite'.
- Mispronouncing the stress (stress is on the second syllable: sa-MAR-skite).
- Using it as a general term for any dark, heavy mineral.

Frequently Asked Questions
Samarskite is a black, radioactive mineral that is an important source of rare-earth elements, uranium, and thorium.
It is named after the Russian mining engineer, Colonel Vassili Samarsky-Bykhovets, who provided the first samples for study.
Yes, because it contains uranium and thorium, it is radioactive. Proper safety protocols for handling radioactive materials should be followed.
It is found in granite pegmatites, which are coarse-grained igneous rocks, often in association with other rare-earth minerals.
