My Flashcards

Definition

Meaning

A rare black or brown mineral that is a complex oxide containing yttrium, tantalum, niobium, and iron.

A mineral of the tantalite group found in granite pegmatites, historically significant in the discovery and study of rare earth elements and tantalum sources.

Linguistics

Semantic Notes

Term belongs exclusively to mineralogy/geology. It refers to a specific crystalline structure with defined chemical composition. Often mentioned in historical contexts of mineral discovery or specialized geological surveys.

Examples

By Part of Speech

adjective

British English

  • The yttrotantalite sample was catalogued.
  • An yttrotantalite crystal structure.

American English

Examples

By CEFR Level

B2
  • Yttrotantalite is a rare black mineral.
C1
  • The geologist identified the black crystalline mass as yttrotantalite, noting its high tantalum content.
  • Yttrotantalite, first described in the 19th century, is primarily found in granite pegmatites in Scandinavia.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'итроколумбит' (yttrocolumbite), a related but distinct mineral.
  • Avoid direct phonetic transliteration; the term is a borrowed international scientific term.

Common Mistakes

  • Misspelling as 'ytrotantalite' (missing one 't').
  • Confusing it with the more common 'tantalite'.
  • Incorrect pronunciation stressing the second syllable.

FAQ

Frequently Asked Questions

It has no direct commercial application. It is a mineral of interest to collectors, geologists, and researchers studying rare earth elements and tantalum ore geology.

It is found in granitic pegmatites, with historical localities in Sweden (where it was first described) and other regions like Norway, Russia, and the United States (Colorado).

Typically not significantly radioactive, as its composition (Y, Ta, Nb, Fe, O) does not usually include strongly radioactive elements. However, associated minerals in pegmatites might be.

In British English: /ˌɪtrə(ʊ)ˈtæntəlaɪt/ (IT-roh-TAN-tuh-lyte). In American English: /ˌɪtroʊˈtæntəlaɪt/ (IT-roh-TAN-tuh-lyte). The primary stress is on the third syllable ('tan').
