Definition

1. Noun:
   • A mineral: "wolframite" is a mineral consisting of iron and manganese tungstate in crystalline form. It is the principal ore of the metal tungsten.
   • A source of tungsten: The term specifically refers to the naturally occurring mineral from which tungsten is commercially extracted. It is typically found in quartz veins associated with granitic rocks.

Examples of Usage

• Noun:
  • The geologists discovered a significant vein of wolframite in the mountains.
  • Tungsten is primarily obtained by processing wolframite.

Advanced Usage

• In a geological context: The term is used precisely to describe a specific mineral with a variable composition between ferberite (iron tungstate) and hübnerite (manganese tungstate).
  • The wolframite in this deposit is particularly rich in iron content.

Variants and Related Words

• Tungsten (n): The metallic element (symbol W) extracted from wolframite.
• Ferberite (n): The iron-dominant end-member of the wolframite series.
• Hübnerite (n): The manganese-dominant end-member of the wolframite series.

Synonyms

• Tungsten ore: A more general term for minerals containing tungsten.
• No direct common synonym exists, as "wolframite" is a specific scientific term.

Related Phrases

• Wolframite series: Refers to the solid solution series between ferberite and hübnerite.
  • The specimen is part of the wolframite series, showing intermediate composition.
