The 11 pages that link to Isomorphous substitution, each with the reason it gives.
Silicate mineralRelated: Such substitutions let aluminum and other elements enter silicate structures.
Clay mineralRelated: Substitution creates much of the permanent negative charge on many clay-mineral layers.
MicaRelated: Substitutions within mica layers create charge that is balanced by interlayer cations.
AluminosilicateRelated: Aluminum commonly replaces silicon in tetrahedral sites, changing framework charge.
PhyllosilicateRelated: Substitutions such as aluminum for silicon create much of the layer charge.
ApatiteRelated: Apatite's anion channels allow fluorine, chlorine, and hydroxyl to substitute for one another.
Chlorite groupRelated: Substitutions among iron, magnesium, aluminum, and other cations create chlorite compositional variation.
FluorapatiteRelated: Fluoride can occupy apatite's anion sites in place of hydroxide or chloride.
BiotiteRelated: Substitutions among iron, magnesium, aluminum, and other ions create biotite’s compositional range.
EpidoteRelated: Iron substitutes for aluminium in epidote, creating compositional variation within the species.
HectoriteRelated: Lithium-for-magnesium substitution creates the charge imbalance characteristic of hectorite.
