Figure 6
Topological analysis of the nanoscopic tubules in eveslogite (Evl) and charoite (Cha) by means of a nodal representation. The topologies of the yuksporite-like tubule (Yk) (a) and charoite-like tubule (Ch) (b) in Evl, as well as the tubule in Cha (c). (d, e, f) The bands corresponding to the topologies shown in (a, b, c), respectively. (g) The topology of the titanosilicate sheet in lamprophyllite. (h) The topology of the silicate sheet in apophyllite and feldspar-group minerals. The scissors indicate the edges that have to be cut in order to transform tubules into bands. The orange circles indicate points that have to be glued together in order to transform bands back to the tubules.
