| Abstract/Notes | Lamellar twinning is of frequent occurrence in corundum, as evidenced by rulings on the surfaces and by the well-marked pseudo-cleavages (or partings) parallel to the faces of the primary rhombohedron and also parallel to the basal plane. Distinctly developed juxtaposition and interpenetration twins would, however, appear to be rare, for only a few isolated examples have hitherto been described.There are two twin-laws for corundum crystals, the twin-plane being either r (101Ì„l) = (100) or c (0001) = (111). The former of these is the one considered in the present note. |
