Ferropseudobrookite-silica mineral-albite-chondrule in the ALH-77015 chondrite (L3)

P(論文) Ferropseudobrookite-silica mineral-albite-chondrule was found in an unequilibraed (L3) chondrite (ALH-77015). This is the first finding of ferropseudobrookite in chondrite. The ferropseudobrookite exhibits a weakly zonal structure. The stability field of ferropseudobrookite suggests that the c...

Description
Summary:P(論文) Ferropseudobrookite-silica mineral-albite-chondrule was found in an unequilibraed (L3) chondrite (ALH-77015). This is the first finding of ferropseudobrookite in chondrite. The ferropseudobrookite exhibits a weakly zonal structure. The stability field of ferropseudobrookite suggests that the chondrule should have been quenched at a temperature near 1140±10℃. departmental bulletin paper
