The intrusive equivalent is melilitolite.[6] When pyroxene is absent from the rock, and the accessory minerals are olivine, magnetite, leucite, kalsilite, nepheline, and perovskite, the rock is sometimes called katungite. However, more modern classification schemes avoid the term katungite and describe the rock instead as (for example) kalsilite-leucite-olivine melilitite, depending on the most abundant accessory minerals.[7] Alnöite is a melilitite devoid of glass or feldspathoids with melilite in its groundmass.[8]
