[100] diffraction patterns, characterized by “wings,” “cusp points,” and “chords” (Baronnet and Devouard 2005), which we interpret as due to intrasector radial stacking faults. Finally, we deal with [010] longitudinal sections, to under- stand the three-dimensional (3D) polytype arrangements. The resulting 3D polytype model is used to index additional reß ec- tions in the XRPD patterns.* E-mail: mugnaioli4@unisi.it Complexity in 15- and 30-sectors polygonal serpentine: Longitudinal sections, intrasector stacking faults and XRPD satellites E.

American Mineralogist, Volume 88, pages 1809–1816, 2003 0003-004X/03/1112–1809$05.00 1809 INTRODUCTION Zinc sulfide (ZnS) crystallizes in various close-packed poly- typic structures. Cubic sphalerite and hexagonal wurtzite are the most common polytypes of ZnS. In addition to sphalerite and wurtzite there exist several other polytypic structures which are mixtures of the two basic polytypes (Smith 1955). Such transi- tion polytypes are produced by the insertion of periodic stacking faults in the cubic or hexagonal modifications. As the energy gap for the
