A fine-grained melilitic rock containing < 10% olivine.
A generally olivine-free extrusive rock composed of melilite with clinopyroxene (or other mafic minerals) usually comprising more than 90% of the rock, with minor amounts of feldspathoids and sometimes plagioclase. Ref: AGI

Mineralogy of Melilitite
Essential minerals - these are minerals that are required within the classification of this rock:
| Melilite | Ca2(Al,Mg,Fe)((Al,Si,B)SiO7) |
Non-essential minerals - these minerals are common, sometimes major components, but are not always present:
| Olivine | Equivalent to Fayalite-Forsterite Series; usually a more or less Fe-bearing forsterite. |
| Pyroxene | A petrological term for Pyroxene Group. |
