A structure hierarchy for silicate minerals: sheet silicates [PDF]

open access: yesMineralogical Magazine, 2018
AbstractThe structure hierarchy hypothesis states thatstructures may be ordered hierarchically according to the polymerisation of coordination polyhedra of higher bond-valence. A hierarchical structural classification is developed for sheet-silicate minerals based on the connectedness of the two-dimensional polymerisations of (TO4) tetrahedra, where T =
