Prossima pubblicazione.

▪ Xie, D., Hirth, G., Hirth, J.P., Wang, J. (2019): Defects in deformation twins in plagioclase. Physics and Chemistry of Minerals, 46, (in press).

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.
