Chemical Composition: | (C. Agee, UNM) Chondrule olivine Fa12.4±6.5, Fe/Mn=41±20, Cr2O3=0.40±0.11 wt%, n=31; chondrule low-Ca pyroxene Fs3.1±1.8Wo0.7±0.8, Fe/Mn=9±3 n=10. Ferroan chondrules with pyroxenes are rare: most pyroxenes analyzed were in Mg-rich type I chondrules, hence the low Fs mean value. |
