摘　　要：随州陨石不透明矿物有陨硫铁、铁纹石、镍纹石、自然铜、含镍黄铜矿、铬铁矿、钛铁矿等。本文对它们进行了反光显微镜鉴定、X射线分析、反射率及硬度的测定和电子探针分析,总结了不同化学群的球粒陨石铬铁矿、钛铁矿中FeO、MgO含量变化规律。A number of opaque minerals were identified in the Suizhou meteorite, including troilite, kamacite, taenite, native copper, nickelo-chalcopyrite, chromite,ilmenite, etc. These minerals were studied using reflecting microscopy, X-ray analysis, reflectivity and hardness determination, electron microprobe, etc. Variations in FeO and MgO contents of chromite and ilmenite in different chemical groups of chondrites are summarized in this paper.
