Abstract
The main objective of this study was to provide a preliminary analysis of the meteorite North West Africa (NWA) 12606 recently classified as ureilite, which was found in 2018 in Morocco, to unveil the possible presence of diamonds. The preliminary analysis of the surface of a meteorite fragment by scanning electron microscopy–energy dispersive spectroscopy (SEM–EDS) and optical microscopy has shown that it mainly consisted of olivine, minor pyroxene and carbon phases possibly including carbon in the form of diamonds. The results achieved are preliminary to a further deeper study of this meteorite as the diamond origin in ureilites is still an open issue debated among the scientific community due to its significant implications for the sizes of early Solar System bodies.

摘要
这项研究的主要目的是对 2018 年在摩洛哥发现的最近归类为 ureilite 的陨石西北非洲 (NWA) 12606 进行初步分析，以揭示钻石的可能存在。通过扫描电子显微镜-能量色散光谱 (SEM-EDS) 和光学显微镜对陨石碎片表面的初步分析表明，它主要由橄榄石、微量辉石和碳相组成，可能包括钻石形式的碳。所取得的结果为进一步深入研究这颗陨石奠定了基础，因为 ureilites 中的钻石起源仍然是科学界争论的一个悬而未决的问题，因为它对早期太阳系天体的大小具有重要意义。
