Euxenites

Part of speech: noun

Definitions

1. A term used in mineralogy to describe crystals of a rare earth ore consisting primarily of niobate and tantalate minerals; commonly refers to a group of complex oxides found in certain igneous rocks; often studied for their distinctive chemical composition and crystal structure
2. Refers to specific silicate-bearing mineral specimens known for containing rare elements such as niobium and tantalum; identifies a type of mineral group important in geological and industrial contexts; denotes crystalline substances valued for their unique physical and chemical properties
3. Designates minerals classified by their content of heavy rare-earth elements combined with oxides of niobium and tantalum; used in scientific research and extraction of valuable metals; characterizes a group of intricate, naturally occurring earth materials with significant mineralogical interest

Etymology: The name rests on a Greek compliment. "Eúxenos" meant "friendly to strangers, hospitable," built from "eû," meaning "well," and "xénos," meaning "stranger" or "guest." The Greeks used it of a good host, someone who treated visitors well, and the word's sense of welcome is what the mineral name carries. English speakers added the mineral suffix "-ite," the standard ending for named minerals, giving "euxenite." The mineral is a complex oxide of niobium, tantalum, titanium and heavy rare-earth elements, and the group name "euxenites" covers the family of closely related minerals that share this chemistry. Mineralogists have long treated the group as intricate, since the same structure can hold many different elements in varying proportions.
