2020523Solid solution series. A solid solution series is the compositional range between endmember minerals that share the same basic chemical formula but experience substitution of elements in one or more atomic sites. This substitution occurs when an element in a mineral formula can be replaced by another of similar size and charge to make a new mineral.

Nonideality in mineral solid solutions affects their elastic and thermodynamic properties, their thermobaric stability, and the equilibrium phase relations in multiphase assemblages. At a given composition and state of order, nonideality in minerals is typically modelled via excesses in Gibbs free energy which are either constant or linear with respect to pressure and temperature.
