chondritic
Definition
- 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.
Adjective
-
