内容記述 |
Fine texture and chemical composition of relict olivines and pyroxenes in a chondrule in the ALH-77015 (L3) chondrite have been studied by a transmission electron microscope with an analytical mode. Dusty cores of the relict olivines have abundant fine inclusions of chromite. In addition, they show dislocations extremely high in density with the predominant Burgers vector of [001]. The dislocations are considered to have been caused by shock impact. Pyroxene grains in the same chondrule show an apparent crystallization sequence of the order of orthoenstatite, clinoenstatite and augite, which cannot be explained by a single crystallization stage. The orthoenstatite crystals are, therefore, considered to be relict. |
