本文利用X射线衍射仪、扫描电子显微镜等手段,研究了取自四川省铜街子某地凝灰岩和火山碎屑岩浅沼湖相堆积物夹层中的绿鳞石。对该矿物的化学组成进行的研究表明,它是一种比较典型的低镁型绿鳞石。
In this paper, X-ray diffraction and scanning electron microscopy were used to study the green scale from the lacustrine facies interlayer of tuff and pyroclastic rocks in Tongjiezi, Sichuan Province. The study of the chemical composition of the mineral shows that it is a relatively low-Mg type green scale stone.
