Popis:	It is shown that experimentally observed departures from Henry's law at high dilution conditions for rare earth elements (REE) in garnet, clinopyroxene and plagioclase can be referred to stabilization in the lattice point defects. The solution process involves negative interaction parameters (−500/−3,000 cal for garnet). On the basis of the experimental data, the activity coefficients of the trace REE can be approximated by a model based on trace cation/cationic vacancy binary solid solution, taking into account association phenomena between them as well.
