内容記述 |
Peculiar mineral aggregates detected in the nonequilibrated Yamato-82133 ordinary chondrite (H3) include regular intergrowths of hercynite and kamacite, sometimes with corundum. In addition to hercynite, kamacite, and corundum, the typical minerals of the hercynite-kamacite objects (HKO) are chrome spinels and phosphates (apatite, whitlockite, and a Ca-free Na-K analog of fillowite). HKO are most widespread in the chondrite matrix but also occur in the porphyritic pyroxene-olivine and olivine chondrules, in which HKO were detected in form of droplets. The latter stick together to produce dumbbell-shaped aggregates. Intrachondrule HKO are zoned and have magmatic textures. Their textural relationships and specific mineralogical features are indicative of the magmatic genesis of intrachondrule HKO and provide information on the composition of the parental melt. The textural identity between intrachondrule and matrix HKO and similarities in their mineral assemblages and mineral chemistries suggest their similar genesis. |
