    In geochemistry, compatibility is a measure of how readily a particular trace element substitutes for a major element within a mineral. Compatibility of an ion is controlled by two things: its valence and its ionic radius. [1] Both must approximate those of the major element for the trace element to be compatible in the mineral.
