IUGS Definition ( QAPF Chart )

Tephritic Foidite: “A collective term for alkaline volcanic rocks consisting of foids with some plagioclase. It is distinguished from basanitic foidite by having less than 10% modal olivine. If possible the most abundant foid should be used in the name, e.g. tephritic nephelinite, tephritic leucotite, etc.”
