Usage: astronomy; geology; technical

Examples

• Scientists classified the meteorite as an achondrite based on its lack of chondrules.
• The achondrite sample provided evidence of planetary differentiation in the early solar system.
• Unlike chondrites, achondrites show signs of having undergone melting and chemical separation.
• Researchers studied the achondrite to understand the composition of asteroid interiors.
• The meteorite collection included several achondrites from different parent bodies.
