1 样品编号: 129
该类样品在中国有一个响亮的名字“陨石钻石夜明珠”,但从矿物的角度,一般认为是萤石,外形也不具备陨石的特征,到底是什么要看分析结果。如果矿物组成就只是氟化钙,那就是萤石,如果里面真含有“朗斯代尔钻石”,那还真应另当别论。

Ref. Code | Compound Name | | Chemical Formula |

所检出的“铝酸锶”是一种长余辉发光材料,近十几年荧光材料的热门研究,该样品显然不像人工合成的荧光材料,也不是我们过去所说的“萤石(氟化钙)”,如果有资料证明地球上不存在天然的铝酸锶,那问题就简单了。
全岩分析中没有发现“朗斯代尔钻石”,不排除含有但浓度过低检测不出的可能。
