摘要
本文根据前人的工作资料以及笔者的研究,探讨一些透明有色矿物在偏振光条件下的可见光光谱特征及其与成分、晶体结构、所含过渡型离子以及颜色之间的关系,进而推测矿物成因类型和岩石的合矿性。通过对不同岩类黑云母的测定说明,随着岩石化学成分的变化,其透射率值具有明显的变化规律。
Based on the previous data and authors' study, the visible spectral characteristics of some transparent coloured minerals under the polarized light are discussed and relationships between the spectral properties and the mineral compositions, crystal structures, transition ions, and colours are revealed in this paper. According to our examination, the mineral origin and ore-bearing potentiality of the rocks are. inferred. The determination of biotites in different rocks indicates that their transmissivity varies clearly and regularly with chemical compositions of the host rocks.
