本文就宇宙尖晶石的形态，化学组成及产状特征作了概要性论述，对它的成因机制作了介绍；并和地球尖晶石作比较，表明它们之间的成因和形成条件的差异，突出了宇宙尖晶石的特点，即宇宙尖晶石为陨石物质在大气氧化过程中结晶而成，无例外的都有一个较高的氧化态和高镍含量。在地质纪录中宇宙尖晶石的发现具有双重意义：它既是地外物质的标志，又反映了增生事件独特的形成环境
In this paper, the morphology, chemical composition and the characteristics of the spinel have been summarized, and the genesis mechanism of the spinel has been described. Compared with the spinel of the earth, it shows the difference of formation and formation conditions between them , Highlighting the characteristics of the cosmic spinel, that is, the cosmic spinel crystallizes from meteorite material during atmospheric oxidation without exception and has a higher oxidation state and a higher nickel content. The discovery of the cosmic spinel in geological records has dual meanings: it is not only a sign of the extraterrestrial material, but also reflects the unique formation environment of the accretion event
