On 21 January 2024, asteroid 2024BX1, discovered the three hours before, fell to Earth south of Ribbeck in the Havelland region of Germany. In this study, fragments of the Ribbeck meteorite, characterized by white and gray colors lithology, were examined for their chemical and phase compositions. The white lithology fragment exhibited a homogeneous chemical and phase structure typical of orthopyroxene, which crystallizes in the orthorhombic system. The gray lithology fragment showed a greater diversity in chemical and phase compositions. Raman spectra analysis revealed that, in addition to the pyroxenes found in the white lithology fragment, minerals from the olivine group (fayalite and forsterite) were also present, along with plagioclase and sulfur in pure crystalline form.
2024年1月21日,三小时前刚被发现的小行星2024BX1坠落在德国哈弗兰地区里贝克以南的地方。在这项研究中,对里贝克陨石的碎片进行了检查,这些碎片的岩性特征为白色和灰色,研究其化学和相组成。白色岩性碎片呈现出典型的斜方辉石的均匀化学和相结构,斜方辉石在正交晶系中结晶。灰色岩性碎片在化学和相组成上表现出更大的多样性。拉曼光谱分析表明,除了在白色岩性碎片中发现的辉石外,橄榄石族矿物(铁橄榄石和镁橄榄石)也存在,还有纯晶体形式的斜长石和硫。
