Abstract
Structural relationships and the effects of isomorphous substitution lead to a new interpretation of the phenomenon of metamictization for these minerals. It is proposed that many possible structures exist with about the same stability, each being favored by slight compositional differences. The metamict state is thus seen as the result of segregation into domains or microregions of different structure and/or composition.
