摘要: — Chondrules in the Bali-like CV chondrite Kaba and Allende-like portion of Mokoia breccia have been studied to explore relationship between hydrous alteration form phyllosilicates anhydrous resulting secondary olivine zonation, replacement enstatite by ferroan formation feldspathoids (nepheline sodalite). All chondrules experienced extensive alteration; whereas, was minor resulted only zonation. On other hand, all both alteration. Bronzite rims formed relic grains during Petrographic observations indicate that postdate feldspathoids. We conclude predated took place before accretion into parent asteroid.
