Polytypism of Micas: OD-Interpretation, Stacking Symbols, Symmetry Relations
Mica Order-disorder Polytypism Stacking symbol Symmetry
2012/2/7
From the symmetry point of view, micas may be classified as follows: those with all three octahedrally coordinated sites occupied by the same cation (homo-octahedral micas), those with only two of the...
Od-Interpretation of Kaolinite-Type Structures—I: Symmetry of Kaolinite Packets and their Stacking Possibilities
Kaolinite-Type Structures Kaolinite Packets
2012/2/14
The idealized symmetry of kaolinite-type minerals (1:1 phyllosilicates) is analysed in detail. They can be considered as OD-structures consisting of three kinds of OD-layers. Each of them, taken separ...
