thortveitite

Thân thiện

A geologist holds a sample of thortveitite in a rock collection.

Definition

Noun: A rare mineral consisting primarily of scandium yttrium silicate (Sc,Y)₂Si₂O₇. It is a significant source of the element scandium.

Usage

"Thortveitite" is a highly specific term used in the fields of mineralogy, geology, and materials science. It refers to a particular mineral species, not a general concept.

Examples

• Geologists discovered a vein of thortveitite in the pegmatite.
• The primary commercial source of scandium is the mineral thortveitite.
• Under ultraviolet light, the thortveitite sample exhibited weak fluorescence.

Advanced Usage

• In mineral classification: Thortveitite is classified as a sorosilicate (or disilicate) mineral, meaning its crystal structure contains isolated double tetrahedra of silicon and oxygen (Si₂O₇ groups).
• In economic geology: The term is used when discussing rare earth element (REE) and critical mineral deposits, as thortveitite is a carrier mineral for scandium, a valuable metal used in aerospace and high-performance alloys.

Variants and Related Words

• Scandium (n): The chemical element (Sc) for which thortveitite is a primary ore.
• Sorosilicate (n): The mineral group to which thortveitite belongs.

Synonyms

• There are no direct common synonyms for this specific mineral name. In technical contexts, its chemical formula (Sc,Y)₂Si₂O₇ may be used descriptively.
