The compositions and textures of olivines in equilibrated ordinary chondrites, C1, C2, and C3 meteorites are described. The olivines are classified by color into blue, red, or dark olivines. The characteristic features of blue olivines are examined. It is observed that the texture of the olivine: (1) forms cores in single olivine grains; (2) shows subhedral to euhedral boundaries against rim olivines; (3) rarely contains inclusions; (4) has embayments containing olivines similar to that of the rim; and (5) occurs within chondrules. The mode of formation for blue olivines, the relation between blue olivine and high temperature compounds, and modifications in the features of blue olivines are analyzed. It is noted that the olivine is a product of condensation, has been modified by additions of olivine formed from a liquid, and that these olivines represent relic grains that are similar to olivines found in cosmic particles and in cores of some deep sea particles.
