During the deformation of plagioclase two types of deformation twin-ning,albite twinning and pericline,twinning,are produced.

在所统计的９个样品内，有６个样品的钠长石双晶几率高于肖钠双晶，其余３个样品的肖钠双晶几率高于钠长石双晶。

Based on the observation under a differential interference contrast microscopy(DIC),the etching figure of faces and sections with different crystallographic significance on α-quartz twinning was studied.

对α-石英双晶上具有不同结晶学意义的晶面和切面进行了腐蚀像的微分干涉显微镜(DIC)观察与研究。

Quartz is commonly found as a six-sided, prism-shaped crystal topped by pyramid-like form, while calcite usually shows a crystal form of rhombohedron.

石英通常呈六方柱，顶上带有双锥的晶形，而方解石却常以菱形六面体形式出现。
