英文摘要 | Twenty-four refractory inclusions (40-230 mu m, with average of 86 +/- 40 mu m) were found by X-ray mapping of 18 ordinary chondrites. All inclusions are heavily altered, consisting of fine-grained feldspathoids, spinel, and Ca-pyroxene with minor ilmenite. The presence of feldspathoids and lack of melilite are due to alteration that took place under oxidizing conditions as indicated by FeO-ZnO-rich spinel and ilmenite. The pre-altered mineral assemblages are dominated by two types: one rich in melilite, referred to as type A-like, and the other rich in spinel, referred to as spinel-pyroxene inclusions. This study and previous data show similar type and size distributions of refractory inclusions in ordinary and enstatite chondrites. |
