隐晶态葡萄石的鉴定

The identification of the cryptocrystal prehnite

隐晶态矿物鉴定是岩矿鉴定中的难题。因其为晶体与非晶质矿物的过渡相,因而不具有可鉴定的光学性质。本文根据成因矿物学分析,判定该标本中呈斜长石外貌的隐晶态矿物为葡萄石。经X射线衍射光谱和红外光谱分析得到确认。本文的意义在于:提出了成因矿物学分析方法为选择最终鉴定隐晶态矿物测试手段的新思路。

The identification of the cryptocrystal prehnite is a difficult work. Because it is a transitional phase of crystal and amorphous mineral, so, it has not identi fiable optical property. According to minerageny analysis (XRD spectrum analysis and IR spectrum analysis), it is determined that cryptocrystal mineral like pla gioclase is prehnite. The significance of the paper is to propose a new train of thought for the identification of cryptocrystal prehnite by the minerageny anal ysis method.
