金伯利岩的一系列标型矿物——石榴石、辉石、橄榄石、碳酸盐、钛铁矿等的成份和性质的研究,对于确定金伯利岩的形成条件和它的含矿(金刚石)性,具有重要的意义。铬尖晶石类也属于金伯利岩的标型矿物之列,目前对它研究得还不够:它们的分析数目不多,关于它们的物理性质、结构和类质同象类型的报导也不完全。红外谱是研究铬尖晶石类有前途的方 Studies on the composition and properties of a series of kimberlite mineral types, such as kimberlite, pyroxene, olivine, carbonate, ilmenite and the like, have been used to determine the formation conditions of kimberlite and its ore-bearing (diamond) , Of great significance. Chromium spinel also belongs to the kimberlites, which are the standard minerals of kimberlite. At present, its research on it is not enough: the number of their analyzes is small, and the reports about their physical properties, structure and isomorphism are not complete. Infrared spectroscopy is a promising method for the study of chrome spinels
