The crystal structure of werdingite, (Mg,Fe)Al(Al,Fe) Si (B,Al)O, and its relationship to sillimanite, mullite, and grandidierite
Werdingite, is a borosilicate mineral newly recorded from Namaqualand, South Africa, which has a structure based on chains of AlO octahedra parallel to c, cross-linked by SiO groups, Al and Mg in five coordination, Al and Fe tetrahedra, and B triangles. The structure was solved by direct methods and...
