A fine to medium grained, extrusive or hypabyssal igneous rock consisting mainly of analcime and pyroxene (usually titanian augite).
Other feldspathoids, plagioclase, and/or olivine may be present. Apatite, titanite, and opaque oxides may be present as accessories.
On the QAPF diagram, it is a foidite consisting of >90% feldspathoids, mostly analcime, with <10% feldspars, and <90% mafic minerals.
