铬尖晶石 [
gè jiān jīng shí]
[矿物] picotite
chrome spinel
- 主要的造岩矿物有橄榄石、辉石、斜长石、铬尖晶石、角闪石。
The main rock-forming minerals are olivine, chrome spinel, pyroxene, plagioclase and amphibole. 2. - 因此,铬尖晶石与辉石的共生连晶结构可以作为豆荚状铬铁矿的重要找矿标志。
Therefore, the intergrowth texture of Cr-spinel and pyroxene can be an important indicator for podiform chromite exploration. - 辉石岩中尖晶石在薄片下呈绿色,为铝含量高、铬含量低的铝尖晶石;
The spinels in pyroxenite xenoliths are aluminum spinel with higher Al content and lower Cr content and green in color in thin sections.
