| Abstract | The great number of (Si[2]O[5]) layer silicates is primarily due to the differences in size and charge of the cations. Anhydrous layer silicates show an increasing degree of convolution of layers with decreasing radius/charge ratio of cations, the size of cation sites between layers decreasing at the same time. This explains why 1+ cations form anhydrous layer silicates and 2+ cations of small or medium size and 3+ cations do not. In hydrous layer silicates the [ MeO(OH)] polyhedra are `effective' cations. The deviation from a plain conformation increases with increasing ratio radius/charge, from Al[4](Si[4]O[10])(OH)[8] and the bent serpentines to the ruffled ones of pyrosmalite and apophyllite. |
