摘要
本文讨论了取自黄山-太平花岗岩基-黑云母的化学成分和不同成因岩体的波谱学特征之间的关系。研究表明它们之间存在着密切关系,可能鉴定并建立黑云母中主要阳离子成分与吸收键特征以及黑云母的谱学特征,也可以用于区分不同成因的花岗岩类型。
In the study of biotite samples from the Huangshan-Taiping composite granitoid batholith in southeastern China, this paper discusses the relationship between the composition (Mg,Fe,Al dominant) and spectroscopic features of biotite from the Huangshan and Taiping rock bodies differing in genesis. The results are well correlated.The investigation shows that it is possible to determine and estimate the cation contents in the biotite in terms of some characteristic absorption bands, and the spectroscopic features of biotite may be also used to distinguish the granitoid types different in origin.
