The study of pristine chondrites provides insight into nebular processes that occurred prior to the accretion of small-sized parent bodies. The interchondrule matrix of the primitive chondrite Acfer 094 is characterized by the presence of submicron-sized anhydrous crystalline aggregates embedded in a silicate groundmass that is mostly amorphous. Transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDXS) were employed to investigate the matrix of Acfer 094 and its components.

亚微米级无水结晶硅酸盐及其与 Acfer 094 基体中无定形硅酸盐的关系


对原始球粒陨石的研究提供了对小尺寸母体吸积之前发生的星云过程的见解。原始球粒陨石 Acfer 094 的软骨间矩阵的特征是存在于大多数无定形的硅酸盐基体中嵌入亚微米大小的无水结晶聚集体。采用透射电子显微镜 （TEM） 和能量色散 X 射线光谱 （EDXS） 研究 Acfer 094 的基质及其成分。
