Definition of xenotime in English: xenotimenoun ˈzɛnə(ʊ)tʌɪmˈzēnə- mass nounA yellowish-brown mineral which occurs in some igneous rocks and consists of a phosphate of yttrium and other rare earth elements. Composition: native yttrium phosphate Example sentencesExamples - Textures of kyanite, xenotime and monazite, and some staurolite and biotite, indicate that peak metamorphic mineral growth occurred after D 2 deformation.
- Zircon, monazite, xenotime and white mica were extracted from the sample.
- I dutifully explained that the smoky spots were probably the result of natural irradiation caused by many tiny radioactive mineral grains, possibly monazite or xenotime.
- Other accessory minerals are apatite, zircon, monazite, huttonite and rare xenotime, uraninite and betafite.
- Pale brown to yellow xenotime and zircon are abundant as fine crystals up to 2 mm in length in many of the miarolitic granite cavities as well as in pegmatite pockets.
Origin Mid 19th century: from xeno-, apparently erroneously for Greek kenos 'vain, empty', + timē 'honour' (because it was wrongly supposed to contain a new metal).
