Macles et déséquilibre cristallogénétique

Kurze Mitteilungen

Summary

A case of twin formation (Fig. 1) in rock-salt is crystallographically studied and a structural interpretation is proposed (Fig. 2). The twinning is produced experimentally by supersaturation of sodium chloride solutions, and appears as an outstanding case of the complications in the process of crystallization caused by desequilibrium during genesis and growth.
