 | | In clino-amphiboles, of tremolite and hornblende type as well as in 2:1 phyllosilicates, talc, phlogopite and clintonite, this study demonstrates the importance of dimensional factors on the extent of solid solutions involving manganese. |
 | | Similarly, in trioctahedral 2:1 phyllosilicates, this study has demonstrated the possibility of occupancy of octahedral sites by manganese, replacing magnesium, and, as a minor element in the interlayer space of clintonite, replacing calcium. |
 | | In talc, the extent of the Mg2+ - Mn2+ replacement is restricted to less than twenty atomic percents, owing to dimensional constraints, concretely, a misfit between tetrahedral and octahedral layers. |
