白云母(KAl_2(AlSi_3O_(10))(OH,F)_2)属于单斜晶系.对不同产地的白云母,有各种过渡金属离子渗入以取代一个AL;主要的金属离子为Fe~(2+)、Fe~(3+)及Mn~(2+)等.它们的含量决定了白云母的色泽;而金属离子的环境晶场,决定了白云母的光谱规律.由于白云母分子结构的复杂性,因而渗杂的过渡金属离子周围环境晶场的规律,一直是一个困难而有趣的课题.
Muscovite (AlSi 3 O 10) (OH, F) 2) belongs to the monoclinic system. For muscovite from different origins, various transition metal ions infiltrate to replace one AL. The main metal ions are Fe ~ ( 2 +), Fe ~ (3+) and Mn ~ (2+), etc. Their content determines the color of muscovite, while the environmental crystal field of metal ions determines the spectroscopic law of muscovite.As the muscovite molecular structure The complexity of the crystal structure of the transitional metal ions in the surrounding environment, therefore, has always been a difficult and interesting subject.
