The topological model is applied to analyze defects associated with albite and pericline twins in plagioclase. Twin growth occurs by the motion of twinning disconnections. The same twinning disconnections are shown to produce both twins. The topological model is used to predict the atomic details of the disconnections. High-resolution transmission electron microscopy results verify the model predictions. Early work on the possibility of pseudo-twinning is also discussed.

斜长石变形孪晶缺陷

拓扑模型用于分析与斜长石中钠长石和周线孪晶相关的缺陷。孪生增长是由孪生断开的运动发生的。显示相同的孪生断开产生两个孪生。拓扑模型用于预测断开的原子细节。高分辨率透射电子显微镜结果验证了模型预测。还讨论了关于伪孪生可能性的早期工作。
