921	LUCTR	Leucitic rock - A type of exotic crystalline igneous rock. In all known leucitic rocks the leucite occurs as phenocrysts and should be readily identifiable in hand-specimen. In the Rock Classification Scheme, this class includes tephritic-leucitite, phonolitic-leucitite, and leucitite, corresponding to the three sub-fields of field 15 on the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram.
