About Leucitite
Foidites with foids (mostly leucite) constituing 60 to 90% of light-coloured constituents.
Now defined modally in the leucite-bearing rock classification in two senses:
(1) sensu lato: as a group name for all leucite-bearing rocks falling into QAPF field 15
(2) sensu stricto: as a rock falling into QAPF field 15c and consisting essentially of leucite, clinopyroxene and olivine > 10%.
