Equilibrated Chondrite

Chondrite with minerals of uniform composition (e.g., all of the olivine grains have the same composition) due to diffusion during thermal metamorphism. Such chondrites would be petrologic type 4 (some thermal metamorphism) to type 7 (complete thermal metamorphism of chondritic material). Type 7 chondrites are also referred to as metachondrites. Type 3 chondrites are referred to a unequilibrated chondrites.
