chondritic

Thân thiện

A meteorite sample displays a chondritic texture under the microscope.

Definition

1. Adjective:
   • Having a granular structure like that of chondrites: Describes a texture or composition that resembles the small, rounded mineral grains (chondrules) found in a specific type of stony meteorite known as a chondrite.

Usage

• The term is primarily used in geology, planetary science, and meteoritics to describe the texture of rocks or materials.
• It is a technical, scientific adjective.

Examples

• Adjective:
  • The sample was identified as chondritic due to its distinct granular makeup.
  • Scientists study chondritic material because it represents some of the oldest, most primitive solids in the solar system.

Advanced Usage

• "chondritic composition": Refers to the chemical makeup of an object (like an asteroid or meteorite) that matches the average elemental abundances found in chondrites, particularly for non-volatile elements.
  • The asteroid's chondritic composition suggests it has remained largely unchanged since the solar system's formation.

Variants and Related Words

• Chondrite (n): A stony meteorite characterized by the presence of chondrules.
  • The museum displayed a rare carbonaceous chondrite.
• Chondrule (n): A small, round granule of minerals, found in chondrites.
  • Under the microscope, the chondrules were clearly visible.

Synonyms

• Granular: Having a texture composed of grains. (Note: "Granular" is a more general term, while "chondritic" is specific to the meteoritic context.)
• Pelletal: Resembling small pellets. (Sometimes used in geological descriptions of similar textures.)

Antonyms

• Achondritic (adj): Lacking chondrules; describing meteorites or materials that have undergone melting and differentiation.
  • In contrast to the primitive chondritic meteorites, achondritic meteorites come from planetary bodies that melted.
