Definition
Noun: 1. A mineral that is a source of rare earth elements: Gadolinite is a black or dark green mineral primarily valued for containing several rare earth elements. It consists of silicates of iron, beryllium, cerium, yttrium, and erbium.
Usage Examples
- Noun:
- The geologist identified the black crystal as gadolinite.
- This deposit of gadolinite is an important source of yttrium.
- The chemical formula of gadolinite is complex, containing multiple rare earths.
Advanced Usage
- Scientific Context: In geology and mineralogy, "gadolinite" is used to refer specifically to this mineral species. It is often discussed in the context of rare earth element (REE) deposits and mineral classification.
- The paragenesis of the gadolinite indicates a late-stage hydrothermal formation.
Variants and Related Words
- Ytterbite (n): An older, synonymous name for gadolinite, named after the village of Ytterby, Sweden, where it was first discovered.
- In early mineralogical texts, you might find gadolinite referred to as ytterbite.
Synonyms
- Mineral: While "mineral" is a general term, it can be used as a synonym in broad contexts where the specific type is understood.
- The sample contained a rare earth-bearing mineral (gadolinite).
Related Terms and Context
- Rare Earth Elements (REEs): A group of 17 chemically similar metallic elements, many of which are found in gadolinite.
- Silicate Mineral: A category of minerals, the largest and most important class of rock-forming minerals, to which gadolinite belongs.
- Type Locality: The location where a mineral was first described. For gadolinite, this is Ytterby, Sweden.
Noun
