Definition

Noun: 1. A yellow radioactive mineral: Carnotite is a specific type of mineral. It is notable for its yellow color and its natural radioactivity. 2. An ore of uranium, radium, and vanadium: Carnotite is an important source (ore) for the chemical elements uranium, radium, and vanadium, which are extracted from it.

Usage Examples

• Noun:
  • Geologists discovered a significant vein of carnotite in the sandstone.
  • The yellow color of the rock sample suggested it might be carnotite.
  • Due to its uranium content, carnotite is both economically valuable and requires careful handling.

• It is often associated with sedimentary rocks, particularly in arid regions.

Variants and Related Words

• Uraninite (n): Another important uranium ore mineral, typically black in color.
• Torbernite (n): A green radioactive mineral that is also a uranium ore.

Synonyms

• Uranium ore: This is a functional synonym describing its primary economic use, though it refers to a category of minerals, not just carnotite specifically.
