Subject has sediment mechanism has minerology has age has likely origin has solidification mechanism has peak temperature has parent body has composition is a kind of has origin has solidification timescale has petrology

differentiated achondrite silicates (with very few exceptions) differentiated meteorite planet or asteroid much larger than 100 km in diameter

primitive achondrite agglomeration of particles, many of which record individual, diverse histories olivine, orthopyroxene, clinopyroxene, metal with some troilite and some sodic plagioclase oldest and most primitive rock in solar system ultrametamorphism, partial melting with some melt migration less than 950 degree Celsius during its entire history since solidification asteroid smaller than 100 km in diameter often minerals not found on Earth undifferentiated meteorite meteoroid from interplanetary space or fragment dislodged from another planet, moon or planetesimal fine- to coarse-grained equigranular
