  • composition similar to mantle and crust 
  • usually stony meteorites
  • surface nodules called chondrules
  • consist spherical aggregates of olivine/pyroxene

CARBONACEOUS CHONDRITE

  • composition similar to solar nebula
  • some have high % of water 
  • they're characterized by olivine/sepentine
  • others have poor volatile content
  • if they've undergone significant heating

ACHONDRITES

  • composition similar to terrestrial basalt
  • assumed to have origin from moon and mars   
  • do not contain chondrules
